Howto handle libxml2 parser errors

Question

I have to use xsd (schema) validation with libxml2, I can set a callback for error-handling, for the schema-validation errors, using: xmlSchemaSetValidErrors().

But before getting to the schema-validation, I have to parse my xml, to get a xmlDocPtr e.g. with xmlParseMemory. But: What if the xml is invalid, how do I set error-handlers for getting these errors? (I don't want them to be printed to stderr) I did not find a function similar to xmlSchemaSetValidErrors for the parsing functions.

You can use xmlSetStructuredErrorFunc and xmlSetGenericErrorFunc. These set error callbacks globally, because as you've noted, there won't be any xmlDocPtr context at this point.
