I want to ignore space, tab, return charactors

[kanghao]

//1)<Root> <A>a</A><B>a</B></Root>
//2)<Root><A>a</A><B>a</B></Root>
Node n = XPathAPI.selectSingleNode(domDoc, "//Root");
System.out.println(n.getFirstChild().getNodeName()); // 1)#text 2)A

The ouput is different depending on the space, tab,return or other charactors.
I want to get number 2) no matter what the charactor is in.
Thanks.

See what happens if you use this instead:

Node n = XPathAPI.selectSingleNode(domDoc, "//Root[b]/*[1][/b]");
System.out.println(n.getNodeName());

Yes it works.
what 's the predicate, [1]?

 

[CubeE101]

[1] = 1st object in node-set
[2] = 2nd, etc...
[last()] = last object
