Java中的Xpath筛选器仅重新带回第一个值结果

Question

I'm new here and to make it short i have this problem. I want to get all values of the Child's that have an attribute"@name='Priority' as an list and i dit this:

    XPathExpression expr = xpath.compile ("//*[@name='Priority']");
        NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
         System.out.println("Found " + nl.getLength() );
            for(int i = 0; i < nl.getLength(); i++) {
                System.out.println("Priority:" + xpath.compile("//*[@name='Priority']").evaluate(nl.item(i)));
                System.out.println("==================");
            }

my XML structure here

  <INSTANCE id="obj.43200" class="Car" name="Car-43200">
        <ATTRIBUTE name="Position" type="STRING">NODE x:15.5cm y:7cm w:1.5cm h:1cm index:69</ATTRIBUTE>
        <ATTRIBUTE name="External tool coupling" type="STRING" />
        <ATTRIBUTE name="Direction" type="ENUMERATION">Horizontal</ATTRIBUTE>
        <ATTRIBUTE name="Priority" type="INTEGER">40</ATTRIBUTE>
     </INSTANCE>

but when i execute the Java Code in eclips i get this:

    Found 9
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================
Priority:40
==================

it brings me only the first result as the end result for all other 8 XPath filter results. It should be like this for exmp:

     Found 2
Priority:40
==================
Priority:5

and so on...

What could I do? Thanks in advance :)

Answer 1

based on the given xml content and java code, output as following

Found 1
Priority:40
==================

i have a no idea about your xml content. please try with this

XPathExpression expr = xpath.compile ("//*[@name='Priority']");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
System.out.println("Found " + nl.getLength() );
for(int i = 0; i < nl.getLength(); i++) {
    System.out.println("Priority:" + nl.item(i).getTextContent());
    System.out.println("==================");
}
