Extract namespace attribute from elements of xml

Question

There is XML file (shown below). I wonder how can I extract namespaces (xmlns attribute) from AppHdr and Document elements using MSXML6.0 parser. I can express path to namespace attribute of AppHdr as "Messages/ :AppHdr/namespace:: ", but it works in xPath 2.0 and above. If I try send xsl with such path (Messages/ :AppHdr/namespace:: ) to msxml6.0 it returns error.

    <?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" encoding="utf-8">
    <xsl:template match="Messages/*:AppHdr/namespace::*">
        <xsl:copy>
            <xsl:value-of select="."/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

msxsl.exe error

Can anybody suggest the right view of xpath-expression?

XML file:

Answer 1

If you want to know in what namespace the AppHdr element is, you can use:

<xsl:value-of select="namespace-uri(/Messages/*[local-name()='AppHdr'])"/>

---

Note that the expression:

/Messages/*[local-name()='AppHdr']/namespace::*

will select all namespaces that are in-scope for the AppHdr element - and in XSLT 1.0 the xsl:value-of instruction will return the string-value of only the first node of the selected node-set.
