This code sample specifies the 'xmlerror= message' option in the xmlparse call. This will store the parsed XML for XML documents that are valid XML, and store a parsed XML error message element for documents that are not valid XML.
insert xmlxfsTab(filename, content) select 'ParsedDir/'+filename, xmlparse(content option 'xmlerror = message') from xmlxfsTab -------------- (4 rows affected)
The following code sample applies the xmlextract built-in function on parsed data and gets the list of non-XML data, along with exception message information.
select filename, xmlextract('/xml_parse_error', content)
from xmlxfsTab
where '/xml_parse_error' xmltest content and filename like 'ParsedDir%'
----------------
Or with xmlrepresentation builtin
select filename, xmlextract('/xml_parse_error', content)
from xmlxfsTab
where xmlrepresentation(content) = 0
and '/xml_parse_error' xmltest content
filename
