Removing XML node using Java

Question

I want to remove XML node from XML based on jQuery result. I have XML like this:

<?xml version="1.0" encoding="UTF-8"?>
<list>
    <member name="James">
        <friendlist>
            <friend>0001</friend>
            <friend>0002</friend>
            <friend>0003</friend>
        </friendlist>
    </member>
    <member name="Jamie">
        <friendlist>
            <friend>0003</friend>
            <friend>0002</friend>
            <friend>0001</friend>
        </friendlist>
    </member>
    <member name="Katie">
        <friendlist>
            <friend>0001</friend>
            <friend>0003</friend>
            <friend>0004</friend>
        </friendlist>
    </member>
</list>

I want to remove complete <member> tag whose name is equal to 'james' so that XML should look like this

<?xml version="1.0" encoding="UTF-8"?>
    <list>

        <member name="Jamie">
            <friendlist>
                <friend>0003</friend>
                <friend>0002</friend>
                <friend>0001</friend>
            </friendlist>
        </member>
        <member name="Katie">
            <friendlist>
                <friend>0001</friend>
                <friend>0003</friend>
                <friend>0004</friend>
            </friendlist>
        </member>
    </list>

I am using following code to get node and delete it but getting same XML as an output. It is not deleting XML node instead giving same XML.

So, how to use xQuery and remove XML node from XML?

General approach: Deserialize (parse) the XML into an object, traverse the object and remove the elements you need to, then serialise back to XML. There are any number of libraries you can use to do this. Look up DOM and SAX parsers. — Dan Temple

"I am using following code [...]". Which code? I don't see any. — Seelenvirtuose

Hi,Dan Temple Can you provide some link or example then it would be more clear to me — Deepali Singh

Are you sure that you mean Java, as you mention jQuery, which is actually JavaScript. — adamretter

Yes , I am sure as I am using java parser to parse xml and using jquery to extract a node(reach a node). — Deepali Singh

I do things like this with XMLBeam:

public class RemoveNode {
    public interface Projection {
    @XBDelete("/list/member[@name='{0}']")
    Projection removeMember(String name);
}

    public void main(String[] args) {
    Projection projection = new XBProjector(Flags.TO_STRING_RENDERS_XML).io.file("yourfile.xml").read(projection.class);
    System.out.println("Before:"+projection);
    System.out.println("After:"+projection.removeMember("james");
    }
}

Not sure if reading the XML from a file meets your setup. But there are several ways to create projections (from IOStream, Resources, DOM Nodes, Strings...)
