I have build a xml interface for a java application. I parse the xml
files using dom parser, get the data and pass it to the java
application. I know that DOM builds a in memory tree of the xml file.
Will this degrade the performance of my application. Will it be
better to use a SAX parser instead?

Depends on the size of your file. If you have a large
file, it will. In any case, SAX is more efficient but
not appropriate in many cases. Have you considered

Depends on the size of your file. I highly recommend you SAX to parse
XML in Java

I've been building application  to read XML files, i was using JDOM
which was fine for small XML file, then when it's a huge one i had
OutOfMemory problems.

Then i changed to SAX, and i have no problems at all. It maybe a
little bit trickier to map the element, especially if it is a very big
XML file  with dupicates element names. But it's definitely worth it.

Alot more efficient than DOM, for sure.

Currently i'm trying to write and read XML file
using java  and i'm using SAX parser. I need help in
two things,
1) How can i travel through the nodes of the the XML
2) How can i write attributes in XML tags.
for example <Name sex="male">......</Name>
