Parsing the SOAP Message as String

Question

I have a SOAP message as a String and need to parse it in Java. I receive an XML file containing the data and the signature of the XML data content as a separate XML part of the same soap message The following is a sample SOAP Message(is not a valid xml) i receive:

I want entire SOAP Envelope, XML containing the data and the XML containing the Signature & Fingerprint as separate DOMs. — cannot_mutably_borrow, Jan 15 '13 at 04:31

The first part is to extract valid (from XML perspective) fragments from your text.

You will have to do the first part manually (= write your own code) or if you are lucky you may find a library which will do it for you.

The second part - feed those fragments to the DOM parser you use.

do you know any such library? – cannot_mutably_borrow Jan 21 '13 at 11:24
@Younis Shah No, I don't. If I were to need it, I would write some helper myself. – Alex Kreutznaer Jan 21 '13 at 16:43

Use a multi-line regular expression to pull out <ackowledgements*.</ackowledgements>and another to pull out <nl:Signature.*<\nl:Signature> and feed those two strings into your dom parser of choice - for an example of how to do that, see In Java, how do I parse XML as a String instead of a file?

i could have tried that, but the problem is in the first part: i dont know what `XML root tag` i will get from a SOAP Message. I can get `` tag or any other root tag. this will however work for the second part, though. – cannot_mutably_borrow Jan 21 '13 at 11:23
your root tag will be the first one after so you use a regex to pull out the whole and parse that, then pull out the 1st childof Body from your dom model which will give you your root. – Steve Atkinson Jan 21 '13 at 18:50
