Dan Harvey commented on WODEN-113:
----------------------------------
I have researched into ways of finding the line number inside Woden and found
that model XML object models try and stay away from linking to the structure of
the document. With DOM it is possible using a sax handler as Lawrence suggested
to add line numbers to the elements as we process them or create a look up
table. There is probably also a similar way to do this with OM.
Another way of possibly doing this would be to provide an XPath, possibly
inside an XPointer to reference an XML document as well, to the element you
want to address inside. This may not be so useful for raw output but if
Eclipse, for example, could parse these out of debug messages or exceptions and
directly link to it this would be quite a powerful, and far more elegant, way
to do it.
One other issue I found is the current way Woden sometimes passes arguments to
auxiliary functions to parse prevents the context of the XMLElement from being
know so its hard to link an error to a location, getWSDLFromLocation() for
example for an embedded wsdl20 document. A way of sorting this out would be to
pass exceptions back up out of these functions to be caught higher up, or pass
the context XMLElement down to be referenced in the case of errors.

> The ErrorInfo interface has methods to return the line and column number of
> the WSDL element or attribute in error, but currently these always return
> zero. This behaviour needs to be implemented. For the DOM implementation of
> Woden, maybe consider subclassing the SAX parser object and extending it to
> capture this information during parsing. Perhaps stored in a separate
> collection, keyed by element qname.
