Saxon

Reported by Nicolas Houillon:

Hi,

I encountered a really weird problem when using an entity resolver with the parser used to read files loaded with the document() function.

I use document() to load a bunch of files that i want to merge, which worked fine until the url in their doctype declaration ceased to work.

As i can't change the original xml files i wrote an entity resolver and supplied it to the parser used by saxon with System.setProperty("javax.xml.parsers.SAXParserFactory", "org.test.TempSAXParserFactory");.

Now, the weird part is that my entity resolver is called on half the document() calls, while the other half fail as if it wasn't there at all (first call works, second fails, third works, fourth fails, etc...).

I made an example to illustrate the problem, that i'm attaching to the post, you can run it with mvn test.

Expected result would be :

I tried with saxon-HE versions 9.4.0.7 and 9.5.0.2 from maven repository, with similar results.
