how to parse an xml file in javascript

[anandraj123]

Hai,

I want to parse an xml document in javascript.
There are many source codes available in internet but i found
all those are hard code ones.

Want exactly i want is i want to validate the xml file using some DTD or
schema then i want to retrieve the data because
there may be some tags are optional.

For one record it may exists for some record is may not exists.

thanx in advance.
