Subject: [Expat-discuss] XML_Parse( ) Stripping the '\r' characters from the
	XML message
Message-ID: <2979E38DD6FC6544B789C8DAD7BAFC520F918CAE@xmb-sjc-235.amer.cisco.com>

HI Folks,

 

I am facing the following problem using EXPAT's XML_Parse() API.

 

I have an XML message shown below,

 

<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n<transaction
length=\"462\"  protocolversion=\"1\">\n <CRREQ>\n<originalreq>GET
http://sjst81.cisco.com/preview.wmf HTTP/1.0\r\nUser-Agent: Wget/1.10.2
(Red Hat modified)\r\nAccept: */*\r\nHost:
sjst81.cisco.com\r\n\r\n</originalreq>\n </CRREQ>\n</transaction>\n"

 

Now after we pass this XML message to the XML_Parse API for parsing, the
output we get does not contain any '\r' characters inside any of the XML
tags. However in my case I need these characters to be still present
there after the XML Parsing.

 

Is this a known issue and is there a workaround to overcome this.

 

Any help is appreciated.

 

Thanks

Swapnil

This is correct behavior.  The line separators \r\n and \r (normally found on
Mac OS 9 and earlier) are normalized to \n.

If you want to encode the \r en the XML, you need to use a character reference:
