Hi Joe,
Your suggestion about getLength() brings to mine attention the
following behavior of unmodified JDK:
If we slightly modify a TestFunc class [1] in such manner:
public static Node test( NodeList list ) {
Node ret = list.item(0);
System.err.println(list.getLength());
return ret;
}
And add more elements to in.xml:
<input1><seq-elem1>inp1_1</seq-elem1><seq-elem1>inp1_2</seq-elem1><seq-elem1>inp1_3</seq-elem1></input1>
The test will fails:
2
Transformation completed. Result:<?xml version="1.0"
encoding="UTF-8"?>inp1_2
Exception in thread "main" java.lang.RuntimeException: Incorrect
transformation result
at XSLT.main(XSLT.java:49)
As you can see the length of 2 is incorrect value and the 'inp1_1'
element is ignored. But If we do another one change to test function -
first get the length() and then get the item:
public static Node test( NodeList list ) {
System.err.println(list.getLength());
Node ret = list.item(0);
return ret;
}
The test will pass:
3
Transformation completed. Result:<?xml version="1.0"
encoding="UTF-8"?>inp1_1
This behavior tells that item() method incorrectly caches the nodes
(The method called first - do the caching). But the caching of nodes
is done in correct way by getLength() function, but its according to
the test results. Currently, I'm trying to understand why it's working
in such way in a view of source code.

Hi Aleksej,
Looks like the getLength() method has the same problem.

Hi Everyone,
There is a bug [1] in JAXP about transformation of one-item sized
node list:
When the length of nodelist which is passed to a XSLT extension
function is 1, the node gotten from the node list becomes null.
New test illustrates this issue [2]. Full webrev with proposed fix
can be found here: [3].
