Question How to deal with the node with ns

Hello there,

Recent I met the problem to deal with the element with ns, what does "ns" mean here. I supposed it means namespace, like
<ns0:PO xmlns:ns0="http://HelloWorld.POSchema"></ns0>
When I tried to use XSLT to read this node and the children node under it, it cannot be right.

The input XML like:
<?xml version="1.0" encoding="utf-8" ?>
<ns0:PO xmlns:ns0="http://HelloWorld.POSchema">
And my XSLT code are below:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var s0 userCSharp" version="1.0" xmlns:ns0="http://HelloWorld.InvoiceSchema" xmlns:s0="http://HelloWorld.POSchema" xmlns:userCSharp="http://schemas.microsoft.com/BizTalk/2003/userCSharp" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <xsl:template match="PO">
    <Number><xsl:value-of select="PO_Number"/></Number>
    <xsl:element name="Invoice">
      <xsl:element name="Number">
        <xsl:value-of select="PO_Number"/>
      <xsl:element name="TotalPrice">
        <xsl:value-of select="Total"/>
      <xsl:element name="Number2">
        <xsl:value-of select="PO_Number2"/>
      <xsl:element name="Number3">
        <xsl:value-of select="PO_Number3"/>
      <xsl:element name="InvoiceRoot">
        <xsl:element name="InvoiceRoot1">
          <xsl:value-of select="PORoot/PORoot1"/>
        <xsl:element name="InvoiceRoot2">
          <xsl:value-of select="PORoot/PORoot2"/>
        <xsl:for-each select="PORoot/POChild/POChild1">
            <xsl:when test=". = null"></xsl:when>
                  <xsl:value-of select="POChild1"/>
                  <xsl:value-of select="POChild2"/>
And the output XML cannot be viewed in IE since it said error.

So my questions are:
1. What is "ns"?
2. How to deal with the XML element with ns;
3. In the XSLT file, what are the attributes of the stylesheet mean?

Hopefully I have described my questions clear..

Thank you all in advance for any help!

There are many tutorials on namespaces and XSLT: this one here


looks as if it might be around the right level for you.
