Parsing a String representation of XML

From a String like

<TestData Identifier=\"Test\" requiredAttribute=\"Present\"></TestData> <TestData Identifier=\"Test1\" requiredAttribute=\"Present1\"></TestData> <TestData Identifier=\"Test2\" requiredAttribute=\"Present2\"></TestData> <TestData Identifier=\"Test3\" requiredAttribute=\"Present3\"></Te开发者_JAVA百科stData>

whats the best way to get the values of the attributes requiredAttribute i.e (Present,Present1,Present2...)

You can look into JAXB unmarshalling. Check out this page for more details, it should point to what you need

For basic XML parsing like this, I've found NanoXML @ http://nanoxml.cyberelf.be/ to be about the easiest and mostlightweight.

Working with XML in Java send you down a long road to pain if you start using all the other libraries.

That's not XML - but you could do it with regex or by converting it to XML and parsing it out. The latter is probably more expensive. It depends on what the actual test data is and your requirements for it.
