[Expat-checkins] expat Usage CDATA node related Query

[p s]

Hi All,
I am trying to parse xml using expat and in the
process I need to get data from a CDATA node. Can some
one help me how to get data from a CDATA node. Here is
my xml

<project>
 <page name="page1">
  <segment name="seg1">
   <![CDATA[ This is page1/segment 1 ]]>
  </segment>
  <segment name="seg2">
   <![CDATA[ This is page1/segment 2 ]]>
  </segment>
 </page>
 <page name="page2">
  <segment name="seg1">
   <![CDATA[ This is page2/segment 1 ]]>
  </segment>
  <segment name="seg2">
   <![CDATA[ This is page2/segment 2 ]]>
  </segment>
 </page>
</project>

here is my C code 

void start(void *data, const char *el, const char
**attr) {
  int i;
  FILE *fp4;
  char acBuff1[50];

/* Attempt to open the dump file */
        fp4 = fopen("../tmp/mmtempfile.txt","a");

  for (i = 0; i < Depth; i++)
        fwrite(" ",1,1,fp4);
        fwrite(el,sizeof(el),1,fp4);

  for (i = 0; attr[i]; i += 2) {
    sprintf(acBuff1," %s='%s'", attr[i], attr[i + 1]);

        if(attr[i+1] == PageName)
        {
        iPage = 1;
        }
        else if(attr[i +1] == SegmentName)
        {
        iSegment = 1;
        }
        fwrite(acBuff1,30,1,fp4);
        fwrite("\n",sizeof("\n"),1,fp4);
  }
        fclose(fp4);
  Depth++;
 }  /* End of start handler */

void end(void *data, const char *el) {
        if(el == "page")
        {
        iPage =0;
        }
        else if (el == "segment")
        {
        iSegment = 0;
        }
         Depth--;
   }  /* End of end handler */

void CDATAstart(void *data)
  {
    FILE *fp2;
        char *cdata;
        fp2 = fopen("../tmp/mmtempfile.txt","a");
      if(iPage == 1 && iSegment == 1)
      {
        fwrite("This is in CDATA",16,1,fp2);
        fwrite("\n",sizeof("\n"),1,fp2);
        fwrite(cdata,sizeof(cdata),1,fp2);  <----
*** Here i need to get the data in CDATA Node **
      }
        fclose(fp2);
  }

void CDATAend(void *data)
  {
   ;
  }

void  getMessageContent1(FILE *fp3,char
*ElementName,char *segment, char *dmmDat
a)
{
        XML_Parser p = XML_ParserCreate(NULL);
  if (! p) {
    fprintf(stderr, "Couldn't allocate memory for
parser\n");
 
  }

  XML_SetElementHandler(p, start, end);
  XML_SetCdataSectionHandler(p,CDATAstart,CDATAend);

        /* Attempt to open the file */
        fp3 =
fopen("../data/MarketingMessage.xml","r");
        if(!fp3)
                return;

  for (;;) {
    int done;
    int len;

    len = fread(acBuff, 1, BUFFSIZE, fp3);
    if (ferror(fp3)) {
      fprintf(stderr, "Read error\n");
        fclose(fp3);
      exit(-1);
    }
    done = feof(fp3);
    if (! XML_Parse(p, acBuff, len, done)) {
     fprintf(stderr, "Parse error at line %d:\n%s\n",

     XML_GetCurrentLineNumber(p),
     XML_ErrorString(XML_GetErrorCode(p)));
        fclose(fp3);
   //   exit(-1);
    }
    if (done)
      break;
  }

        XML_ParserFree(p);
        fclose(fp3);
  return;

}

The gerMessageContent1 is the function where my
parsing starts with arguments as the File pointer for
xml file,variable PageName, variable SegmentName and
the pointer for storing the data in CDATA node.

I was trying this for the last 3days and wasn't
fruitfull can some one help me .

Thanks in advance
