Which in turn allowed me to fine-tune the xpath statement. I have it working now, somewhat anyway. (I suspect the page may simply be too complex to pull out *exactly* what I want, but I'm getting closer at least.)

Greetings, and question
Hello all, just getting up to speed on Cocoon, and finding it all quite fascinating. No doubt I'll have many more questions in the coming months. Anyway, today's question is on xpath. I'm trying to customize the HTML Generator 'scraper' example to extract bits from a given HTML page. Now, I have rudimentary knowledge of xpath syntax, but not enough I guess because I'm stuck. Here's a sample of the HTML to be scraped: --- table width=100% border=0 bis t=pr f=p020326.htm tr td nowrap align=right valign=top 26 Mar 2002 nbsp; /td td valign=top Financial Stability Forum holds its seventh meeting (a href=p020326.htmRead/a) /td /tr /bis bis t=pr f=p020318.htm tr td nowrap align=right valign=top [snip] /td /tr /bis Etc. -- The bis... stuff is used by another, non-XML process, but it seemed to me it should be a no-brainer to write an xpath argument that would pull out between the bis /bis and transform them. However, it isn't. Can anyone point me in the right general direction here? - Brent Eades, Almonte, Ontario http://www.almonte.com http://www.bankofcanada.ca - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Greetings, and question
Brent, if you want to process the nodeset enclosed in the bis element, you could just try this: xsl:template match=/ xsl:element name=page xsl:apply-templates/ /xsl:element /xsl:template xsl:template match=bis xsl:element name=biselement xsl:copy-of select=./ /xsl:element /xsl:template But this is plain XSLT matching, nothing to do with XPATH. BTW, I've noticed your HTML is NOT XML-compliant, which will cause problems to XSLT: mind !
