Re: [xml] Memory leak using xmlSchemaParse()

[Barbara PHILIPPOT <barbara philippot camptocamp com>]

Thanks for your answer!

Actually, I've found the problem and a way of avoiding it. The function 
was called with : 
XML_SchemaValidation("http://path/schema.xsd",my_xml_file);
and the error in valgrind is due to the connection to http (even if the 
schema is correctly loaded and the program executes well). So if I copy 
the schema locally on my computer, there aren't any more memory leaks.
So I can use my application without error :-) but apparently, there are 
memory leaks when loading a file via http. (I used XmlInitParser() once 
at program startup and called once xmlCleanupParser() at the end and 
since valgrind didn't point out an error in my program, the error may 
come from the library)

Anyway, thanks for your help!

Best regards,

Barbara
