Question

I’m parsing a huge word file with Test descriptions, and have a problem of scope of nodes. Word basically creates a list of paragraphs and I want to group them into a parent node. So for each node ‘A’ I want to group all the following nodes up to the next node ‘A’ into ‘A’.

How can this be done with XSL?

Example: I’ve gotten to :

<A/> <ab/> <ac/> <A/> <ab/> <ac/> 

But need:

<A> <ab/> <ac/> </A> <A> <ab/> <ac/> </A> 

Thank you!

If you mean to match all the nodes following <A>, but come before the next <A>, I think you can use something like this:

<xsl:template match='A'>   <xsl:copy>     <!-- start of range -->     <xsl:variable name='start' select='count(preceding-sibling::*) + 1' />     <!-- end of range -->     <xsl:variable name='stop'>       <xsl:choose>         <!-- either just before the next A node -->         <xsl:when test='following-sibling::A'>           <xsl:value-of select='count(following-sibling::A[1]/preceding-sibling::*) + 1' />         </xsl:when>         <!-- or all the rest -->         <xsl:otherwise>           <xsl:value-of select='count(../*) + 1' />         </xsl:otherwise>       </xsl:choose>     </xsl:variable>      <!-- this for debugging only -->     <xsl:attribute name='range'>       <xsl:value-of select='concat($start + 1, '-', $stop - 1)' />     </xsl:attribute>      <!-- copy all nodes in the calculated range -->     <xsl:for-each select='../*[position() &gt; $start and position() &lt; $stop]'>       <xsl:copy-of select='.' />     </xsl:for-each>   </xsl:copy> </xsl:template> 

For your input:

<root>   <A />   <ab />   <ac />   <A />   <ab />   <ac /> </root> 

I get (I left the ‘range’ attribute in to make the calculations visible):

<A range='2-3'>   <ab />   <ac /> </A> <A range='5-6'>   <ab />   <ac /> </A>
