How to parse the same xml file multiple times?

[komal mangtani]

My code looks like this :

for (int i=0; i<2; i++) {
                        java.io.StringReader inString = new StringReader(MsgHeader);
                        DOMParser parser = new DOMParser();
                        InputSource in = new InputSource(inString);
                        parser.setFeature("http://xml.org/sax/features/namespaces", true);
                        parser.parse(in);
}
 

It works. However,  I do not want to create StringReader and InputSource in every iteration.

If I put them outside the loop, I got "org.xml.sax.SAXParseException: The root element is required in a well-formed document" after the first parsing.

I added inString.reset() after the first parsing, and got the following error java.io.IOException: Stream closed
         at java.io.StringReader.ensureOpen(Unknown Source)
         at java.io.StringReader.reset(Unknown Source)
         at FileParser.execute(FileParser.java:352)
         at FileParser.main(FileParser.java:388)

Does any one know how the stream got closed ? Is it possible to reopen it without create a new StringReader?
