[jdom-interest] How to remove a child by specifying the value of an attribute?

[Benjamin Kopic]

Have a look at Jaxen (http://www.jaxen.org/), which is compatible with JDOM.
You can specify an XPath expression to filter on and then detach the element
from the tree.

You might use something like this:

Document myDoc = saxBuilder.build();
XPath xPath = new JDOMXPath("*/[value1='17']");
Element bbbToRemove = xPath.selectSingleNode(myDoc);
bbbToRemove.detach();


I hope this helps, but make sure that you read the documentation first.
