I have done something like this with the IPSV taxonomy using XQuery, I
suspect that the general premise holds though.
Basically you need a recursive function that checks for the existence of
a child node, if the child node exists then the function should call
itself passing in that child node as the argument to operate on, and so
on...
In XSLT, you would use a template that call's itself
In XQuery this looks like this (included for illustrative purposes only)
-
declare function local:processNode($node as node()) as node()*
{
<tr>
<td>{node-name($node)}</td>
</tr>,
(: process children :)
for $child in $node/child::node()
return local:processNode($child)
};
for $node in /TopTag/TaxonomyEntries/TaxonomyNode return
local:processNode($node)
So XSLT would be something like this perhaps (untested, and written off
the top of my head, so the syntax may need tweaking) -
<xsl:template name="processNode">
<xsl:parameter name="node"/>
<tr>
<td><xsl:value-of select="{node-name($node)}"/></td>
</tr>
<xsl:for-each select="$node/child::node">
<xsl:call-template name="processNode">
<xsl:with-parameter name="node" select="."/>
</xsl:call-template>
</xsl:for-each>
</xsl:template>
<xsl:for-each select="/TopTag/TaxonomyEntries/TaxonomyNode">
<xsl:call-template name="processNode">
<xsl:with-parameter name="node" select="."/>
</xsl:call-template>
</xsl:for-each>

Hi
Does anybody know how do you process nodes within a tag that are nested to
an undefined depth.
I have a tag structure that looks like this:
<TaxonomyEntries>
- - -<TaxonomyNode> (1 to infinity)
- - - - - -<Description />
- - - - - -<TaxonomyNode /> (0 to infinity)
- - -<TaxonomyNode>
<TaxonomyEntries>
And I have some XML that looks like this:
<TopTag>
<TaxonomyEntries>
<TaxonomyNode name="Arbitrary Name"> -----Top Level Node
<Description>any description</Description>
<TaxonomyNode name="another name">
<TaxonomyNode name="yet another name">
<Description>any description</Description>
<TaxonomyNode name="and yet another name">
<Description>any description</Description>
</TaxonomyNode>
</TaxonomyNode>
</TaxonomyNode>
</TaxonomyNode>
<TaxonomyNode name="Arbitrary Name"> -----Top Level Node
<Description>any description</Description>
<TaxonomyNode name="another name">
<Description>any description</Description>
</TaxonomyNode>
</TaxonomyNode>
</TaxonomyEntries>
</TopTag>
I need to apply a stylesheet (XSL v2.0) to this XML to create a Table in
Word so that each Top Level TaxonomyNode is in a separate Table Row and
the children and childrens-children are all nested accordingly with their
descriptions displayed.
<w:tbl>
<w:tblPr>
<w:tblGrid>
<w:tr>
<TaxonomyEntries>
<w:tr>
<w:tc>
<w:p>
<TaxonomyNode name="Arbitrary Name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
<TaxonomyNode name="another name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
<TaxonomyNode name="yet another name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
<TaxonomyNode name="and yet another name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
</TaxonomyNode>
</TaxonomyNode>
</TaxonomyNode>
</TaxonomyNode>
</w:p>
</w:tc>
</w:tr>
<w:tr>
<w:tc>
<w:p>
<TaxonomyNode name="Arbitrary Name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
<TaxonomyNode name="another name">
<Description>
<w:r>
<w:t>any description</w:t>
</w:r>
</Description>
</TaxonomyNode>
</TaxonomyNode>
</w:p>
</w:tc>
</w:tr>
</TaxonomyEntries>
<w:tbl>
Could any one give me some pointers on how to achieve this nesting. It
seems to me that some sort of recursion is in order but I'm not sure how
to implement it when there is no fixed depth to the nesting i.e there is
no break-out parameter.
Hopefully
Andy
