Finding the node value in XML

[praveen kumar]

Hello,

I have xml file in the format(where "<" replaced with < and ">" replaced with > format and '"' replaced with "

I am a newbie to java program

Now my problem is to find the value of a particular node?,
so how can I parse this xml to find the vale of a node.

---XML FILE---
<transmission_info>
<mechanism value="fax"/>
<fax_info>
<transmit_info>
<faxno value="11111111"/>
<cover_text value="Please process this order in a timely manner."/>
<retries value="3"/>
<wait value="300"/>
</transmit_info>
</fax_info>
</transmission_info>

-----END-------

For example say: Find the vale of (fax no) from the above XML.

Unless you want to create your own parser technology, you are most likely looking for SAX, or DOM.

SAX and DOM work differently but will serve your need.

There are free implementations of these parsers. Try find in apache website.

Also, Java has JAXP, which is an API for SAX, DOM and others.

The XML classes in Java 1.4 and 1.5 can do this, no need to get another library. There are plenty of tutorials on the web.
Unless your XML input document is huge, parsing into a DOM Document will be the simplest approach.

Praveen, there's a set of useful examples at the Java Developer's Almanac on how to use the DOM API, for example.
