java - Parsing XML, skip certain tags -

i next mkyong's great tutorial on how parse xml in java, have situation need read tags within area. e.g.

<?xml version="1.0"?> <company> <staff id="1001"> <firstname>yong</firstname> <lastname>mook kim</lastname> <nickname>mkyong</nickname> <salary>100000</salary> </staff> <staff id="2001"> <firstname>low</firstname> <lastname>yin fong</lastname> <nickname>fong fong</nickname> <salary>200000</salary> </staff> <changes> <staff id="2001"> <firstname>low</firstname> <lastname>yin fong</lastname> <nickname>fong fong</nickname> <old_salary>175000</salary> <new_salary>200000</salary> </staff> </changes> </company>

in tutorial uses nodelist nlist = doc.getelementsbytagname("staff"); retrieves of staff, including 1 under <changes>. how can disregard <staff> tags under <changes>?

thanks

using dom parser not best need. using xpath queries should better. (api)

for exemple :

documentbuilderfactory dbf = documentbuilderfactory.newinstance(); documentbuilder db = dbf.newdocumentbuilder(); document doc = db.parse(new file("test.xml")); xpath xpath = xpathfactory.newinstance().newxpath(); string look = "/company/staff"; //read nodelist using xpath nodelist nodelist = (nodelist) xpath.compile(expression).evaluate(doc, xpathconstants.nodeset);
