In my XML document the parser for XPath version 1.0 i.e. Sax6.5.5 works fine if your root document has this type of format:

<odva_cip_output_root>

However as soon as you add a schema and a namespace to this the XPath ceases to parse or find correct XML tags at all!

<odva_cip_output_root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.odva.org/schemas/ODVAcip.xsd"
xsi:schemaLocation="http://www.odva.org/schemas/ODVAcip ODVAoutput.xsd">

I need XPath and the parser for transformations to work with a schema and name space defined. Any ideas what is going on?

Hi,

This is a common issue that people encounter when they are using XPath with documents that contain default namespace declarations. The name tests without a prefix test for elements in no namespace. To test for elements in a namespace you need to declare the namespace bound to some prefix and use that prefix to qualify the element names.

Hi George,

My StyleSheet Code is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" indent="yes"/>


<xsl:template match="/">
<html>
<body>
<center><h1>Ethernet I/P Performance Test Results</h1></center>
<xsl:apply-templates select="//ethernet_ip_device_communication_report" mode="Match_ALL"/>
</body>
</html>
</xsl:template>


<xsl:template match="device_information" mode="Match_ALL">
<h2>Device Information </h2> 
Manufacturer <xsl:value-of select="manufacturer"/> 
Device Name <xsl:value-of select="product_name"/> 
Model Number <xsl:value-of select="serial_number"/> 
Short Description <xsl:value-of select="product_name"/> 
Firmware Version <xsl:value-of select="major_revision"/> 
</xsl:template>

</xsl:stylesheet>

My XML code partial is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="ODVAoutput.xsl"?>

<odva_cip_output_root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.odva.org/schemas/ODVAcip.xsd"
xsi:schemaLocation="http://www.odva.org/schemas/ODVAcip ODVAoutput.xsd">

<ethernet_ip_device_communication_report>
<device_information>
<vendor_id>23422</vendor_id>
<manufacturer>Acme Widgets, Inc.</manufacturer>
<device_type>12</device_type>
<product_code>3000</product_code>
<major_revision>1</major_revision>
<minor_revision>1</minor_revision>
<serial_number>W3000-01-001</serial_number>
<product_name>Distributed I/O Block</product_name>
</device_information>

I am not certain where the prefix needs to be for the parser to recognize the XML tag names with regards to a prefix namespace.
