I have an XML document similar to the following:

<DataInformation xmlns:a="http://www.me.com/ASettings"
xsi:type="a:Stuff1">
<a:Name>Matt</a:Name>
<a:TN>555-5555</a:TN>
</DataInformation>

<b:Name>Bob</b:Name>

</DataInformation>

What I would like to do is take all the namespaces and throw them in
the garbage! For example, I want to remove the xmlns attribute from
the Data node, I want to remove all the "a" and "b" prefixes from all
the nodes, etc. I want the final outcome to look like the following:
<DataItems>
<Data>
<DataInformation type="Stuff1">
<Name>Matt</Name>
<TN>555-5555</TN>
</DataInformation>
</Data>
<Data>
<DataInformation type="Stuff2">
<Name>Bob</Name>
<TN>555-6666</TN>
</DataInformation>
</Data>
</DataItems>
I am using C++ and Microsoft's xml implementation (DOM). I have no
choice but to use the raw Microsoft interfaces.
Does anyone have a good idea of how to do this?
XSLT is good for such tasks, the following stylesheet throws out all
namespace prefixes from element and attribute nodes:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" />
<xsl:template match="/">
<xsl:copy>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="@* | node()" />
</xsl:element>
</xsl:template>
<xsl:template match="@*">
<xsl:attribute name="{local-name()}"><xsl:value-of select="."
/></xsl:attribute>
</xsl:template>
<xsl:template match="text() | processing-instruction() | comment()">
<xsl:copy />
</xsl:template>
</xsl:stylesheet>
The transformation is done with a JavaScript and MSXML 4 as follows (I
know you asked about C++ but I have never used MSXML with C++ thus I
hope you will be able to translate the JavaScript into C++):
var sourceDocument = new ActiveXObject('Msxml2.DOMDocument.4.0');
sourceDocument.async = false;
sourceDocument.preserveWhiteSpace = true;
sourceDocument.validateOnParse = false;
var loaded = sourceDocument.load('test20040408.xml');
if (loaded) {
var xslDocument = new ActiveXObject('Msxml2.DOMDocument.4.0');
xslDocument.async = false;
loaded = xslDocument.load('test20040408Xsl.xml');
if (loaded) {
var resultDocument = new ActiveXObject('Msxml2.DOMDocument.4.0');
sourceDocument.transformNodeToObject(xslDocument, resultDocument);
resultDocument.save('whatever.xml');
}
}
While I tested I have seen that the transformtion is not quite doing
what you want as you also seem to want to remove any "prefixes" in
attribute values so you need to change the stylesheet to use the
following template for attribute nodes:
<xsl:template match="@*">
<xsl:attribute name="{local-name()}">
<xsl:choose>
<xsl:when test="contains(., ':')">
<xsl:value-of select="substring-after(., ':')" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="." />
</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:template>
