XML parser

I was looking at a tutorial

http://www-128.ibm.com/developerworks/education/xmljava/xmljava-2-13.html

see , the parsers has been developed in many languages ....java,c++,perl,python etc

suppose, I am writing a java program .

i want to use a parser to parse my XML .

can i use a parser made ofpython?

If so, howcomplex it is to use it in a java program ?

by complexity i mean , whether there would some JNI call involved or not .

or it would be as easy to use any XML parser made in java because of the W3C specification .

In other words ,

C++ developer should use C++ parser.

JAVA developer should use JAVA parser

Python developer should use Python parser.

is it necessary ? do we have to follow this rule ?

Any input ?
