Thanks for the FAQ.
I figured it out myself (with a lot of help from this post, found in the
archives:
http://www.biglist.com/lists/xsl-list/archives/200408/msg00855.html)
I use the xsl for transforming Bookmark Lists to a Tree, but it could also
be useful to generate Directory Trees from Listings.
It is almost the same as the solution in the post mentioned above, except
that the path information is stored in an attribute.
BUT:
If the path attributes are unsorted, the script ends in an infinite
recursion.
I suppose this is the part, where the recursion doesn?t stop:
<xsl:with-param name="xbelflat" select="$xbelflat[starts-with(@path,
$newPath) and @path != $newPath]"/>
Does someone have an idea how I could recursive group, without sorting by
@path?
The stylesheet takes the following input and produces XBEL formatted XML
(http://pyxml.sourceforge.net/topics/xbel/)
XML:
...
<bookmark href="http://slashdot.org/"; name="Slashdot: News for nerds, stuff
that matters" path="Bookmarks/Bookmarks Toolbar Folder/"></bookmark>
<bookmark href="http://www.heise.de/"; name="heise online"
path="Bookmarks/Bookmarks Toolbar Folder/"></bookmark>
<bookmark href="http://futurezone.orf.at/"; name="ORF ON Futurezone"
path="Bookmarks/News/"></bookmark>
....
XSLT:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"

Hi list!
Does someone know a method to create a nested xml Tree
structure from file listing with paths?
