Question

I have a sample xml file which looks like the one below:

<Root>
    <SubOne>
       <book author="george" />
       <indiv name="abc" />
       <indiv name="khh" />
       <indiv name="ioo" />
    </SubOne>
    <SubTwo>
       <indiv book author="hamle" />
       <indiv name="kok"/>
       <indiv name="ppp" />
    </SubTow>

</Root>

Is there a way in XPATH to check , if author=”george” select /Root/SubOne/indiv/@name , or if the author=”hamle”, select /Root/SubTwo/indiv/@name.
Any help is appreciated

First I noticed that your XML is not valid.

Assume that your XML is as follows.

XML:

<Root>
    <SubOne>
        <book author="george"/>
        <indiv name="abc"/>
        <indiv name="khh"/>
        <indiv name="ioo"/>
    </SubOne>
    <SubTwo>
        <book author="hamle"/>
        <indiv name="kok"/>
        <indiv name="ppp"/>
    </SubTwo>
</Root>

XPATH:

For @author='george', use this XPATH:

//*[book[@author='george']]/indiv

For @author='hamle', use this XPATH:

//*[book[@author='hamle']]/indiv

For both XPATH, to print the name use @name

JAVA:

Using Java, you need to implement this way for both xpath’s

For @author='george',

String xpath = "//*[book[@author='george']]/indiv";
NodeList nl = (NodeList) xpath.evaluate(xpath, xml, XPathConstants.NODESET);
for (int i = 0; i < nodes.getLength(); i++) {
    System.out.println(nodes.item(i).getAttributes().getNamedItem("name").getNodeValue()); 
}

For @author='hamle',

String xpath = "//*[book[@author='hamle']]/indiv";
NodeList nl = (NodeList) xpath.evaluate(xpath, xml, XPathConstants.NODESET);
for (int i = 0; i < nodes.getLength(); i++) {
    System.out.println(nodes.item(i).getAttributes().getNamedItem("name").getNodeValue()); 
}
