Looking for JDOM2 XPath examples

I am using JDOM2 for the first time and I am looking for some XPATH based examples. Ex: My XML looks as follows ``` <Root> <Parent id="1"> <Child id="1" /> <Child id="2" /> <Child id="3" /> </Parent> <Parent id="2"> <Child id="1" /> <Child id="2" /> <Child id="3" /> </Parent> <Parent id="3"> <Child id="1" /> <Child id="2" /> <Child id="3" /> </Parent> </Root> ``` My background is .NET & XPATH traversing is very easier with System.XML I am working on a (new to) Java application where I need to use XML. I am planning to use JDOM2. I want to use DOM parsing and not SAX. I am looking for some examples on how to use XPATH with JDOM2. Ex. How can I navigate to an element let's say `"/Root/Parent[@id='2']/Child[@id='3']"` Can you guys give me some examples? I searched but I couldn't find one for JDOM2
