How to find xml tags in string content?

Question

I have a String content that comes from any soap XML request.

I want to I identify a specific tag <FieldName> having the value MyFieldIndicator , and from there fetch the value of the next occuring <FieldValue> .

How could I do this? Is there any library? Or which mechanisms could be used to extract those tags from a plain string?

Performance matters, so it should be as quick as possible.

Answer 1

the library dom4j is probably easiest to use and understand. You need to create a Document-Object from string and then access via iterators the tags. The documentation and examples can be fopund here

Generally u can probably use any DOM or SAX parser.

Other DOM parser : W3C, JDOM

SAX parser : JAXP

If u by any chance want to store the content into an object : try to learn JAXB
