Need to copy all nodes, attributes, and namespaces

juaniux · October 21st, 2004, 07:59 PM

I am using xsl:copy to make a copy of an xml document, but I need to add a namespace to a "monkey" element, in addition to whatever namespaces it already has.

How can I ensure all "monkey" elements have an added namespace?

The standard way is to create a basic copying stylesheet and then add specific templates to match any special nodes. When you say add a namespace do you mean that previously the element was in no namepsace and now it must be? In that case something like this:

Code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="node()|@*">

    <xsl:copy>

      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <!--
    Templates to match nodes that need changing go here
  -->
  <xsl:template match="monkey" xmlns:new="http://myNewNamespace">
    <new:monkey>
      <xsl:apply-templates select="node()|@*"/>
    </new:monkey>
  </xsl:template>
</xsl:stylesheet>

Otherwise post a small sample of your before and after xml.

I had the top part (standard copy) exactly the same as the one you suggest, but my node matching template was a little different. Basically I needed to insert a namespace of my own, while copying whatever namespace it already had.

You suggest:

<xsl:template match="monkey" xmlns:new="http://myNewNamespace">
    <new:monkey>
      <xsl:apply-templates select="node()|@*"/>
    </new:monkey>
  </xsl:template>
</xsl:stylesheet>

I had:

<xsl:template match="monkey">
    <monkey xmlns:new="http://myNewNamespace">
      <xsl:apply-templates select="node()|@*"/>
    </monkey>
  </xsl:template>
</xsl:stylesheet>

This latter part almost worked, but one of the namespaces' value was empty. I don't know why it wouldn't copy the namespace completely.

What does the <new:monkey... do?

Can you show what you mean?

Creates a new element, monkey in the namespace referred to by "new" prefix.

Mmm...I reloaded the xml and xsl and ran the transformation again, and it now works. It copies everything and inserts the new namespace in the node I specified.

If you had to name three tools for this task that come to mind, which would they be? Commercial and open source. I used Stylus, and I'm not sure I like it.
