It's essentially a recursive grouping problem. (Yes, I have seen these
before!) In XSLT 2.0 you can solve it like this:
<xsl:template name="g">
<xsl:param name="files" as="element(file)*"/>
<xsl:param name="level" as="xs:integer"/>
<xsl:for-each-group select="$files"
group-adjacent="tokenize(@path, '/')[$level]">
<folder name="current-grouping-key()">
<xsl:call-template name="g">
<xsl:with-param name="files" select="current-group() except ."/>
<xsl:with-param name="level" select="$level + 1"/>
</xsl:call-template>
</folder>
</xsl:for-each-group>
</xsl:template>
I haven't tried to distinguish folders from files here, I leave that as an
exercise for the reader (perhaps best done in a second pass).
A 1.0 solution is beyond my concentration powers at this time on a Friday
evening.

Subject: [xsl] Tree from directory listing
Hi list!
Does someone know a method to create a nested xml Tree
structure from file
listing with paths?
eg.
...
<file name ="f1.xyz" path="/test/"/>
<file name ="f2.xyz" path="/test/folderInFolder/"/>
<file name ="f3.xyz" path="/test/folderInFolder/"/>
<file name ="f4.xyz" path="/test/folderInFolder2/"/>
<file name ="f5.xyz" path="/test2/folderInFolder3/"/>
...
to
<folder name="test">
<folder name="folderInFolder">
<file name="f2.xyz"/>
<file name="f3.xyz"/>
</folder
<folder name="folderInFolder2">
<file name="f4.xyz"/>
</folder
<folder name ="test">
<folder name="folderInFolder3">
<file name="f5.xyz">
</folder>
</folder>
Maybe anyone solved a similar problem?
