fess crawler can be find WebDav URL?

(from github.com/nactac)
I’m trying to search WebDAV on apache.
Crawler succeed to get first page like a below.
I hope crawler appends child dir “BuildTools” and “src” to child urls, but didn’t so.

debug log
DEBUG Storing child urls: []
was shown.

<?xml version="1.0"?><?xml-stylesheet type="text/xsl" href="/svnindex.xsl"?>
<!DOCTYPE svn [
  <!ELEMENT svn   (index)>
  <!ATTLIST svn   version CDATA #REQUIRED
                  href    CDATA #REQUIRED>
  <!ELEMENT index (updir?, (file \| dir)*)>

<svn version="1.8.10 (r1615264)"
  <index rev="39165" path="/Applications/FpScan" base="SPL-Series">
  <updir href="../"/>
  <dir name="BuildTools" href="BuildTools/" />
  <file name="build.bat" href="build.bat" />
  <file name="readme.txt" href="readme.txt" />
  <dir name="src" href="src/" />

It is because of this page is not html?
Is needed to parse after load svnindex.xsl?

It’s not WebDAV problem.
Fess does not transform it by XSLT.

Thank you for your answer.

So in this case, is there no way to reference sub directories?

I solved this problem by apache WebDav setting.
I published another URL of same directories with no SVNIndexXSLT setting for fess crawler.
