Java – how to parse XML documents?

I have XML documents in variables (not in files) How to store data in it? I don't have any other files. I put it in my source code When I use

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(XML);

(XML is my XML variable), I received an error

java.io.FileNotFoundException: C:\netbeans\app-s7013\<network ip_addr="10.0.0.0\8" save_ip="true"> File not found.

Solution

Read XML into stringreader, wrap it in inputsource, and pass it to documentbuilder:

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(xml)));
