Best way to use content from one file in another?

["Joe D. Williams" <jo...@mindspring.com>]

I would like a menu that displays links to all files within a given
directory. The director generator can do this, but I would like to use each
file's "title" element rather than the file's "filename" attribute.

CInclude? XInclude?

I can use the document() function in an XSL to do this, but that seems
inefficient.

Suggestions?

You're right, you can use the xpathdirectorygenerator. My first attempt to
do something alike (listing files and describe it by some element in that
file) was also the cinclude transformer:

    <map:generate type="directory" src="data/{1}">
         <map:parameter name="depth" value="1"/>
    </map:generate>    // this gives me just the dir:file/dir:directory like
below, without the description/xpath
    <map:transform src="set_the_includes.xsl"/>
    <map:transform type="cinclude"/>
    // then style it to create links with description

afterwards I replaced it with this (shorter way):

    <map:generate type="xpathdirectory" src="data/{1}">
         <map:parameter name="xpath" value="/description"/>
         <map:parameter name="xmlFiles" value="\.x.*$"/>
    </map:generate>
    // then style it to create links with description

 This gives me:
<dir:file name="article2.xml" lastModified="1057183738609" date="03.07.03
00:08" size="234">
    <dir:xpath query="/description">
      <description>My second article!</description>
    </dir:xpath>
  </dir:file>Just look into the userdocs that come with the cocoon, under
generators its all there!Kind regards,Jan

CInclude or Xinclude are the best choices here. There seems to be a
caching-issue with using the document()-function.

I havent noticed any performance issues between Cinclude and Xinclude, but
Xinclude implements a standard, and also supports the Xpointer
specification, allowing you to specify directly the title-element of the
included file.

There is also an XPathDirectoryGenerator, allowing you to peek into the
files at generator-level, but I haven't looked at it yet.
