Parsing xml stored in string

Question

I have an string encoded in xml format. So when I print it to console it will come out looking like an xml file. What I want to do is read values from this string now using java with DOM or SAX library. But I don't know how to do it because my string is not stored in a file.

can you post your xml and what values do you want to get out of it? if you can sample input and expected result would be nice — justMe, Feb 11 '13 at 15:48
How would I go about getting the root node and just the text called ADT_A01 (won't always be the same). When I try to get it I always get the tage [#text:] — zms6445, Feb 11 '13 at 15:59

For DOM, one option is to use an InputSource:

String str = "<xml>...</xml>";
DocumentBuilder builder = DocumentBuilderFactory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(str)));

You can use a similar strategy with SAX, since it supports InputSource as well.

Thanks. I have this root node Is there any way to just get the text ADT_A01 (it will not always be called ADT_A01) – zms6445 Feb 11 '13 at 15:56

If you're using the DOM, you can use `getDocumentElement()` on the `Document` object to get the root element and then on that returned `Element` object you can call `getTagName()` or `getLocalName()` if you want a non-namespaced name. – Marc Baumbach Feb 11 '13 at 16:09
