Re: Applying transforms to parent nodes based on child

However, now I want to also strip the tags from the parent of the node
with style='strip'.

Just a soot from the hip: modify your template to match
elements which have a child with an appropriate attribute.
Note that your spec is somewhat incomplete, it's not
quite obvious what should happen to siblings of elements
with a style="strip" attribute. The template will strip
them too:
         <xslt:template match="*[*/@style='strip']">
                 <xslt:value-of select="."/>
         </xslt:template>
This should work for your sample XML.
