Hey
rodneyHAlright fella....right your question is a little confusing for a number of reasons. I understand now that you want to know the values with the ? Character placeholders but there are issues with any forum member answering your question.
Firstly you keep mentioning that you need to identify the container datatype, and you give an example like pet=tiger so it appears youre trying to identify a group name and individual values for that, but we (forum members) would not know this, this would be part of your requirement (like an xml schema....xml schemas often have the file extension of .xsd. an xml instance is posted to a listening webservice and the xml instance is then compared/validated against the xml schema (.xsd file) to ensure the file is formatted correctly and the values populating the elements and elements' attributes are correct...e.g. has correct length, datatype (string, or numeric, etc.) content pattern, etc.
The xml that youve copied into your post has a number of errors in it so i can youve edited it, but on top of that, it looks like the content of a schema file, rather than an xml instance (which is the payload you submit to the web service).
Going back to your example pet=tiger.....if you publish your schema file we would be able to build a wellformed and valid xml instance (payload) for you, we might be able to determine the group/individual values for you, but we'd need that detail at the very minimum and it depends om how detailed the schema is before anyone could do that.
Hope this helps a little
Cheers,
