Subject RE: DO NOT REPLY [Bug 12235] New: - [PATCH] XPathTransformer
Date Tue, 03 Sep 2002 00:11:28 GMT
Hi,

For the record, I would say it is very easy in XSL.  This was from the original
bug report:

<map:parameter name="include" value="/manual/s1[@title='{1}']"/>

To get this with xsl you could simply:

<xsl:apply-templates
  select="document($book_param)/manual/s1[@title=$section_title_param]"/>

Now, the problem might be that the book is too large... (probably not for Saxon,
though)

best,
-Rob
