Subject Re: Read XML document via http with variables
Date Mon, 09 Jun 2003 09:58:12 GMT
Hello Daniel,

you probably must build the request string step by step, because the 
variable $cn would not get evaluated otherwise:

<xsl:variable name="xindiceRequestString">
 
<xsl:text>http://localhost:8080/cocoon1/mount/02288/xmldb2/02288/</xsl:text>
   <xsl:text>?xpath=course[contains(prerequisites/courseno, '</xsl:text>
   <xsl:value-of select="$cn"/>
   <xsl:text>')]</xsl:text>
</xsl:variable>

<xsl:for-each select="document($xindiceRequestString)//course">
   ...
</xsl:for-each>

1. But be aware of a problem using document():
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10203

Maybe it's better to use XInclude or CInclude or sitemap aggregation:
http://cocoon.apache.org/2.0/userdocs/transformers/xinclude-transformer.html
http://cocoon.apache.org/2.0/userdocs/transformers/cinclude-transformer.html
http://cocoon.apache.org/2.0/userdocs/concepts/sitemap.html

(If you use Cocooon 2.1 simply replace the 2.0 by 2.1.)

2. And is it really necessary to use //course. Double slashes are almost 
always very time-consuming. I would change it to a more exact XPath.

3. Is it possible to replace the server's root 
http://localhost:8080/cocoon1/ by cocoon:/ to access simply Cocoon 
without HTTP. It's only an inner request and much faster:

http://cocoon.apache.org/2.0/userdocs/concepts/sitemap.html

Regards,

Joerg
