Java Xpath if else Sentence

I have some problems when I use If Sentence inside a For to delete some nodes in a XML document, because I don't understand why my counters become to 0 after put the If Sentence:

public static void main(String[] args) throws Exception {
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    Document document = dbf.newDocumentBuilder().parse(new File("input3.xml"));


    XPathFactory xpf = XPathFactory.newInstance();
    XPath xpath = xpf.newXPath();

    XPathExpression expres = xpath.compile("//TNMS/TPaths/TPath[Topology/LayerSet/NonTerminatedLayers/Layer='RS64']");
    NodeList PathsCount = (NodeList) expres.evaluate(document, XPathConstants.NODESET);

    System.out.println("Inicia el Borrado:");

    for (int i = 0; i < PathsCount.getLength(); i++)

    {

    System.out.println(i);

    XPathExpression exprueba = xpath.compile("/TNMS/TPaths/TPath[1]/Topology/LayerSet/TerminatedLayers");
    NodeList Count = (NodeList) exprueba.evaluate(document, XPathConstants.NODESET);
    System.out.println("Hay " + Count.getLength());
    int countvar = Count.getLength();

    XPathExpression expression = xpath.compile("//TNMS/TPaths/TPath[Topology/LayerSet/NonTerminatedLayers/Layer='RS64']");
    Node b13Node = (Node) expression.evaluate(document, XPathConstants.NODE);
    b13Node.getParentNode().removeChild(b13Node);

    }

I see next in the output:

Inicia el Borrado:
0

Hay 0

1

Hay 1

2

Hay 1

3

Hay 0

<?xml version="1.0" encoding="UTF-8" standalone="no"?><TNMS>
    <TPaths>

    </TPaths>
</TNMS>BUILD SUCCESSFUL (total time: 0 seconds)

But when i agree the If sentence:

public static void main(String[] args) throws Exception {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        Document document = dbf.newDocumentBuilder().parse(new File("input3.xml"));


        XPathFactory xpf = XPathFactory.newInstance();
        XPath xpath = xpf.newXPath();

        XPathExpression expres = xpath.compile("//TNMS/TPaths/TPath[Topology/LayerSet/NonTerminatedLayers/Layer='RS64']");
        NodeList PathsCount = (NodeList) expres.evaluate(document, XPathConstants.NODESET);

        System.out.println("Inicia el Borrado:");

        for (int i = 0; i < PathsCount.getLength(); i++)

        {

        System.out.println(i);

        XPathExpression exprueba = xpath.compile("/TNMS/TPaths/TPath[1]/Topology/LayerSet/TerminatedLayers");
        NodeList Count = (NodeList) exprueba.evaluate(document, XPathConstants.NODESET);
        System.out.println("Hay " + Count.getLength());
        int countvar = Count.getLength();

        if (countvar == 1){

        XPathExpression expression = xpath.compile("//TNMS/TPaths/TPath[Topology/LayerSet/NonTerminatedLayers/Layer='RS64']");
        Node b13Node = (Node) expression.evaluate(document, XPathConstants.NODE);
        b13Node.getParentNode().removeChild(b13Node);

        }

        }

the output is the next:

    Inicia el Borrado:
0

Hay 0

1

Hay 0

2

Hay 0

3

Hay 0

and the erase is failed.

Any ideas?
