Pulling xml attributes with java

[jimmybambino]

Can someone tell me how I would pull an attribute value from a xml element if I had a value of another attribute within that same element? I need to do this with java. Can you help?

Thanks

I'm sorry, my question wasn't worded in the most clear manner. For example, if I had this:

<Root>
<Element attr1 = &quot;value1&quot; attr2 = &quot;value2&quot;/>
<Element attr1 = &quot;anothervalue1&quot; attr2 = &quot;anothervalue2&quot;/>
</Root>

and I wanted to search for the element that had the attr2 attribute value of &quot;value2&quot; and need to return the value of the attr1 attribute. Can you do this in Java? I'm not sure if this is more clear. I hope so.

If you mean return the String from attr1 after finding the Element using attr2 as a filter, yes.

Are you parsing the XML into a DOM tree? If so you would perform an XPath query using //Element[@attr2=’value2’]

Then cast the returned Node to an Element and return it’s getAttribute(“attr1”);
