Subject: [Expat-discuss] Running expat without install library
Message-ID: <001301c315e2$b1b83ee0$96348c2f@ldantec>

Has anyone tried running expat without installing the library on Vx Works or Solaris 7?
(By this I mean compiling the source files directly into an executable)
If so, any hints on setting up the makefile?

I might need to encoporate Expat on a box where I am not allowed to install the libraries.

Thanks,

L.

You should be able to build expat as a static library rather than 
dynamic. When you build your executable, the necessary object code from 
the static lib will be included in the executable, and you won't have to 
install the lib.

This method is basically equivalent to compiling the expat source 
directly into your executable, but I think it'll be easier (in terms of 
modifying the makefiles or whatever).

Cheers,
dr

Just link with the .a file. It's an "archive" of object files.

Subject: [Expat-discuss] getting offsets of attributes
Message-ID: <006c01c31961$5dd1f9b0$4f5b288a@cadfael>

Hello everybody,
sometime ago I asked whether it was possible to get the offset of attributes in some way similar to XML_GetCurrentByteIndex. 
The answer was no. 
So I found my own way to do it and would like to share. I am aware that there might be better (=more efficient, more robust) ways to do that.
Basically my idea is to get the file being parsed (assuming it's in stdin), then change the pointer to stdin so it points at the beginning of the current xml element, then get the whole element tag into a string, finally find the relative offset of the attributes inside the string.
Here is the code, added to the start handler (adapted from the code I used in my program, so there might be some mistakes, though I tried looking at it carefully...).

static void
start(void *data, const char *el, const char **attr)
{

/* Meaning of variables:
   current_pos = position in xml file being parsed
   xml_byte_proc = bytes already processed 
     Basically xml_byte_proc = BUFFSIZE * (Number of BUFFERS already processed)
   element_offset = absolute offset of current element
   element_tag = contains the text of the whole current element tag
   att_info[] = array containing attributes' offsets and lengths
*/

...
current_pos = ftell(stdin);
element_offset = XML_GetCurrentByteIndex(xmlp) + xml_byte_proc;
fseek(stdin, element_offset, SEEK_SET);
j=0;
while((element_tag[j++] = getc(stdin)) != '>');
element_tag[j] = '\0';
for (j=0; attr[j]; j += 2) {
  att_info[j] = strlen(element_tag) - strlen(strstr(element_tag, attr[j]));
  att_info[j+1] = strlen(attr[j+1]);
}
/* I'm not sure it's necessary to record first current_pos in stdin and then
   restore it at the end of the processing, but I do it just to be sure... */
fseek(stdin, current_pos, SEEK_SET);

It works for my needs.
Bye,

Fabio

Subject: [Expat-discuss] Pb with & and &amp; in parsing
Message-ID: <HDEKJFAJBPBFMGLFHILOIEGLCHAA.rbinse@profileup.com>

Hi

I have a strange problem with expat and perl. I?m parsing a xml file with
things like &amp;.  After parsing, they are translated to &.

For example, with <tag1>gfgffghfh &amp; fdsfdsf</tag1> I get gfgffghfh &
fdsfdsf

And it?s the same problem with quotes
 Is there a way to deactivate that ?
Or is it an encoding problem ?

I?m using Expat 1.95.4 and perl 5.8.

There is no way of deactivating this, and this is behaviour as in specs
(http://www.w3.org/TR/REC-xml#sec-physical-struct): all recognized
entities are expanded by parser for application. So &amp; becomes &, &lt;
- <, and so on

Hi,
I want to use expat for my C++ implementation. My objective is just to parse the XML file.
The start, end and character data handlers are implemented as methods of a class. Now, I cant use the expat directly as, the function pointer forces me to include the class name while declaring.
So, the start handler declaration in expat.h should include the class name where the start handler is actually implemented. How do I tackle this. Please help me out.

Thanks & Regards,

There are a few options:

You could use global functions as handlers, and pass the object reference
through the userData parameter. The function will then use this reference
to call the actual class method.

Or, you could use one of the C++ wrappers, like Arabica.
Check out the links on http://www.libexpat.org/#wrappers.

There are lots of c++ wrappers for expat on the web, just do a google
search on expat C++ Wrapper.  Here is two:

http://www.codeproject.com/soap/expatimpl.asp
http://www.oofile.com.au/xml/expatpp.html

I actually wrote my own since we are doing c++ for vse if you can belive
that!  Using inheritance worked well for me.  I wrote a c++ expat wrapper
to be used as a base class.  This base class has virtual functions for all
the different events I want to respond to.  So now all I have to do is
inherit from my base class and voila, I have a c++ class that reads xml and
functions for handling start tag, end tag, char data, etc...

Expat is so cool you can easily write all kinds of wrapper classes to fit
your needs!

Here is some sample code.

I want to use expat for my C++ implementation. My objective is just to
parse the XML file.
The start, end and character data handlers are implemented as methods of a
class. Now, I cant use the expat directly as, the function pointer forces
me to include the class name while declaring.
So, the start handler declaration in expat.h should include the class name
where the start handler is actually implemented. How do I tackle this.
Please help me out.

Thanks & Regards,

SUBHASHINI

Hi, Alan, and Hi all

I got your C++ class for expat. But I have a problem.
I can't compile a project from the source in my Visual C++.
That's because the expat itself is in C. If I try to compile it
in C++, many compatibility issues arise.

Do you (Alan) have a working project in Visual C++, all , C++,
with the source code of expat and your C++ class ?
If you have, I would definitively appreciate to receive a copy of it.

Thanks

Try this.

Note you must go into project setting in VC++ 6.0 and change:

1. On the C++ tab, change Additional Include Path to point to directory
that contains expat.h.
2. On the Link Tab, change Additional Librarry Path to point to directory
that contains libexpat.lib.
3. Make sure libexpat.dll is in your path.

Again, this code is a very very light wrapper.

We did this on purpose because we like the flexibility of expat, but wanted
an easier interface to use with c++.

Hi Alan, hi all

Thanks the project you sent.
But however working, that's not what I was looking for.

I wanted a full-from-source-code project in C++ to work in Visual C++.
That's because I quite often use unix and g++ as well.
I would like to use the same source when using unix.
It would be very good to have a set of source files that
are easy to compile and use.

That is, I want a working VC project that does not rely on a binary library.
Expat does come with source code. But as I told you,
Expat is written as a tricky C (not C++) code.
For example: The source code of Expat includes *.c.
C++ compilers won't accept the Expat C code as C++ (due to those tricks).
I tried to "fix" the expat source, to make it fit for C++,
but there are too many tricks, so I got confused.

So, however having the expat source code, I still do not have
a working C++ set of sources that if compiled produce the
desired effect. That's what I'm looking for.
I wonder if you or anyone can help me on that.

Thanks in advance

But, if you want to have expat cooperate with C++ by means of VC++, why
not use static linkage to *.lib file and access it through number of
wrappers? VC++ knows how to link to *.objs in C-originated *.lib and call
its functions, AFAIK gcc for sure must have that "feature".

So, solution I prefer is to compile or download static LIB and tell linker
to use it. It does _is_ external binary library, but is not any, after
linker produces an exe. U have flexibility of expat written in "tricky C",
avail to C++ and no DLL/so tossing around - that's what tiggers like best
:)

... I would like to join to Sergio. This feature was available in
expat v. 1.1 (it's C source was platform independent and simple to
incorporate into any other source code, C++ in my case). Of course I
can understand why running configure script is needed for all
demanding applications but as it is now I prefer to use the "obsolete"
version 1.1.

Would it be possible to add "platform independent configuration" to
expat?

There are lots of c++ wrappers for expat on the web, just do a google
search on expat C++ Wrapper.  Here is two:

http://www.codeproject.com/soap/expatimpl.asp
http://www.oofile.com.au/xml/expatpp.html

I actually wrote my own since we are doing c++ for vse if you can belive
that!  Using inheritance worked well for me.  I wrote a c++ expat wrapper
to be used as a base class.  This base class has virtual functions for all
the different events I want to respond to.  So now all I have to do is
inherit from my base class and voila, I have a c++ class that reads xml and
functions for handling start tag, end tag, char data, etc...

Expat is so cool you can easily write all kinds of wrapper classes to fit
your needs!

Here is some sample code.

thanks

I'm getting the error : "junk after document element". I've looked through archives and see it usually comes up when there are multiple roots or text after the root element. I don't think this is the case here. I'm parsing two files each with different definitions - the first parses fine but it
doesn't seem to matter what I take out of the second it doesn't parse. I did see mention in the archives of a problem parsing subsequent XML files delivered by socket - here they are read off disk. Here is the second file :

<?xml version="1.0"?>
<!DOCTYPE apptasks[
	<!ELEMENT send_ani_dnis_name EMPTY>
	<!ELEMENT send_iscp_params EMPTY>
	<!ELEMENT return_itag_params EMPTY>
	<!ELEMENT task (send_ani_dnis_name?, send_iscp_params?, return_itag_params?)>

I'm calling XML_ParserFree() after parsing the first file and XML_ParserCreate() before. The parsing of both files is done in the same thread but in a different scope using C++ (C version of expat I believe).

the case here. I'm parsing two files each with different definitions - the first parses fine but it
doesn't seem to matter what I take out of the second it doesn't parse. I did see mention in the
archives of a problem parsing subsequent XML files delivered by socket - here they are read off
disk. Here is the second file :

<?xml version="1.0"?>
<!DOCTYPE apptasks[
<!ELEMENT send_ani_dnis_name EMPTY>
<!ELEMENT send_iscp_params EMPTY>
<!ELEMENT return_itag_params EMPTY>
<!ELEMENT task (send_ani_dnis_name?, send_iscp_params?, return_itag_params?)>
<!ATTLIST task task_id NMTOKEN #REQUIRED>
]>

<apptasks>
<task task_id="101">
<send_ani_dnis_name/>
</task>
<task task_id="102">
<send_iscp_params/>
</task>
<task task_id="103">
<send_iscp_params/>
<return_itag_params/>
</task>
</apptasks>

I'm calling XML_ParserFree() after parsing the first file and XML_ParserCreate() before. The parsing
of both files is done in the same thread but in a different scope using C++ (C version of expat I
believe).

I couldn't see anything wrong with your code.

Does this happen always with the second file you parse, not matter which file?
Or is it always the same file? Have you checked the file for extra characters at the end?

You could also try this:
...
  if(XML_Parse(p, buf, len, len == 0) == XML_STATUS_ERROR)
...

Thanks for your help Karl. Using your suggestion stopped the error and pointed to the real problem. For reasons beyond my ken I had shadowed the done variable so it was changing value with each loop - mea culpa not expat.

I should have caught this. Well, at least we know now. ;-)

We are actually quite proud (knock on wood !!!) that we haven't
received any real bug report (for a programming error) in a long time.

Do not to treat the input as string. This gives
problems if there a re null bytes, like in a UTF-16 encoding.
Just follow the examples in the docs and demo programs that
come with Expat.

Your main problem is that you're treating your file as a C string, which 
may not be a correct assumption. You're in C++, so use fstreams. Try 
something like this:

void parse (std::istream& data) {
   /* ... setup ... */
   char buffer[256];
   while (!data.eof()) {
     a_Data.read(buffer, 256);
     XML_Status status =
       XML_Parse(parser, buffer, data.gcount(), data.eof() ? 1 : 0);
   }
   /* ... error handling ... */
}

Cheers,
dr

Thanks for the response. The problem is solved. But I see that the character handler is called more than once even though I have just one block of word in between my tags. The consecutive calls to character handler do not have any text associated with them.

If there are line breaks, Expat will have to normalize them,
which interrupts the character handler callbacks. So you
should see line breaks in those calls that you consider empty text.

Subhashini,

I didn't receive the full text of your reply to my post (only the part 
quoted in Karl's reply) but here's what I tend to do:

>>Thanks for the response. The problem is solved. But I see that the character handler
>>is called more than once even though I have just one block of word in between my tags. 
>>The consecutive calls to character handler do not have any text associated with them.

You'll get multiple character callbacks in a number of instances. Line 
breaks are one such case, entity normalization and CDATA blocks also 
cause this. What I tend to do in my own code is coalesce the multiple 
character callbacks into one (with logic like "keep adding to my string 
until I get some other callback"), and pass the resulting complete 
string on to my application.

Hope this helps,
Dan
