[xslt] error handling

[Raphael Vallazza <raphael caronte net>]

hi :)

i'm implementing a libxslt module for php and i've got problems with
error handling.

i have a structure like this:

struct xslt_processor {
	xmlParserCtxtPtr xml_ctx;
	xmlParserCtxtPtr xslt_ctx;
	xsltStylesheetPtr xslt_stylesheet;
 char *last_error;
}

xslt_processor->last_error should contain the concatenated errors (if
there where some ;) caused by parsing xml_ctx, xslt_ctx and the
stylesheet. This way i can call a function like
xslt_error(xslt_processor), that returns the last error of the
xslt_processor.

Is there a way to solve this problem? I with xsltSetGenericErrorFunc and
xmlSetGenericErrorFunc, but it didn't solve the problem.

thanx for your help,
raphael
