Any errors found during parsing.
apr_xml_parser* apr_xml_parser_create ( apr_pool_t pool)

Create an XML parser

poolThe pool for allocating the parser and the parse results.
The new parser.
apr_status_t apr_xml_parser_done ( apr_xml_parser parser,

Terminate the parsing and return the result

parserThe XML parser for parsing this data.
pdocThe resulting parse information. May be NULL to simply terminate the parsing without fetching the info.
Any errors found during the final stage of parsing.
Use apr_xml_parser_geterror() to get more error information.
