Cannot find JDOM node through xpath after clone

I have a xml document, and I use JDOM to parse it and use XPATH API provided by JDOM to find some element, it works well.

Example: <person> <info name="gg" age="0" hobby="hi" /> </person>

Through API:

XPath.selectSingleNode(baseElement,"//*[local-name()='info");

I can get the correct info.

Then I try to clone a new baseElement with baseElement.clone().

After that, if I try:

XPath.selectSingleNode(baseElementClone,"//*[local-name()='info");

I got nothing.

The only diff I can image is that after clone, it will lose the parent info. But I dont why it will affect the search result.

Pls let me know if you think the question is unclear.

BTW, my JDOM version is 1.0
