Re: [xsl] Suggestion for handling an endless loop

Text change in stylesheet only, so I changed this:

<xsl:stylesheet version="2.0">

to this:

<xsl:stylesheet version="1.0">

That's the entire fix. I did not change XSLT processors or any other code.

When you say you "change it to 1.0", do you mean that you change the version number in the xsl:stylesheet element, or that you change the XSLT processor you are using, or both?

I'm getting what appears to be an endless loop while running XSLT 2.0. It hangs when transforming a certain XML file, and I can watch the memory consumption rise to as much as 9 GB, and it apparently will never end. I have to force it to stop. When I change it back to XSLT 1.0, it runs fine, and when it hits the same file it hung up on with 2.0, it transforms in a second or two with 1.0. The XSLT does not use any 2.0 capabilities yet. The only change is changing 2.0 to 1.0 in <xsl:stylesheet version="2.0">.

I'm interested in methods to debug something like this. Where to look? I notice Oxygen has an XSLT profiler.

The XSLT is running under the DITA Open Toolkit version 3.3.2 (late model). I am converting an HTML-based publishing output from a much older version of the DITA OT, 1.8.5 (where the code worked). It looks like the 3.3.2 OT uses Saxon-HE-9.8.0-14.jar.
