I do not what is the Probelm

an Example

xml with xsl

XML, XSLT and XPATH Syntax (Toggle Plain Text) 
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <?xml-stylesheet type="text/xsl" href="process.xsl"?>
  3. <ProcessData>
  4. 	<SessionBeginTime>2009-07-14 13:24:28.218</SessionBeginTime>
  5. 	<ServerResponse>
  6. 		<Code>226</Code>
  7. 		<Text>226 Transfer OK</Text>
  8. 	</ServerResponse>
  9. 	<DocumentList>
  10. 		<DocumentId>dev4206:80f4cb:12279c825a4:176f</DocumentId>
  11. 		<DocumentId>dev4206:80f4cb:12279c825a4:1773</DocumentId>
  12. 		<DocumentId>dev4206:80f4cb:12279c825a4:1776</DocumentId>
  13. 	</DocumentList>
  14. 	<Prev_NotSuccess_Adv_Status>Primary document is null</Prev_NotSuccess_Adv_Status>
  15. </ProcessData>

xsl

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output indent="yes" method="html"/>
	<xsl:template match="/">
		<html>
			<xsl:apply-templates select="ProcessData"/>
		</html>
	</xsl:template>
	<xsl:template match="ProcessData">
		<table border="solid 3px">
			<tr>
				<th>DocumentList Nr.</th>
			</tr>
			<xsl:apply-templates select="//DocumentId"/>
			<tr>
				<td>
               <!-- here is the count command-->
					<xsl:value-of select="concat('Summe  : ',count(//DocumentId))"/>
				</td>
			</tr>
		</table>
	</xsl:template>
	<xsl:template match="DocumentId">
		<tr><td><xsl:value-of select="position()"/></td>
			<td>
				<xsl:value-of select="."/>
			</td>
		</tr>
	</xsl:template>
</xsl:stylesheet>

then will be create a Html page

XML, XSLT and XPATH Syntax (Toggle Plain Text) 
  1. <html>
  2.   <table border="solid 3px">
  3.     <tr>
  4.       <th>DocumentList Nr.</th>
  5.     </tr>
  6.     <tr>
  7.       <td>1</td>
  8.       <td>dev4206:80f4cb:12279c825a4:176f</td>
  9.     </tr>
  10.     <tr>
  11.       <td>2</td>
  12.       <td>dev4206:80f4cb:12279c825a4:1773</td>
  13.     </tr>
  14.     <tr>
  15.       <td>3</td>
  16.       <td>dev4206:80f4cb:12279c825a4:1776</td>
  17.     </tr>
  18.     <tr>

What do you mean? How are you using your browser to get the count. Can you show us your stylesheet?

Hi,
Am not using any stylesheet here. I'm working on Gentran Integration Suite and the xml file which I've given is the file generated from Gentran server. I want to get DocumentId count in developing one of the Business Process(BP), so I tried externally to find the count(Pls check below), but couldn't. To my surprise count(//DocumentId) worked well in the server. But I don't know why it's not working with the below code. Could please help me. Thanks in Advance...

// Sample HTML file
<code>
<html>
<body>
<script type="text/javascript">
function loadXMLDoc(fname)
{
var xmlDoc;
// code for IE
if (window.ActiveXObject)
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null);
}
else
{
alert('Your browser cannot handle this script');
}
xmlDoc.async=false;
xmlDoc.load(fname);
return(xmlDoc);
}
xml=loadXMLDoc("/home/miracle/Desktop/ProcessData.xml");
path = "count(//DocumentId)"

// code for IE
if (window.ActiveXObject)
{
var nodes=xml.selectNodes(path);

for (i=0;i<nodes.length;i++)
{
document.write(nodes[i].childNodes[0].nodeValue);
document.write("<br />");
}
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
var nodes=xml.evaluate(path, xml, null, XPathResult.ANY_TYPE, null);
var result=nodes.iterateNext();

while (result)
{
document.write(result.childNodes[0].nodeValue);
document.write("<br />");
result=nodes.iterateNext();
}
}
</script>
</body>
</html>
</code>

// Here is XML file generated by Gentran server
