Re: question about parsing XML using Xerces

[legolas wood]

Thank you for reply.
I looked at Xpath API, but it just return an string  as the result of 
evaluation.
while I need it to return a NodeList or something similar to it.

imagine that i want to pars something like :

<Student-Names>
    <name>ABC</name>
    <name>BBC</name>
    <name>CBC</name>
    <name>ACB</name>
</Student-Names>
 
<Teacher-Names>
    <name>ABC</name>
    <name>BBC</name>
    <name>CBC</name>
    <name>ACB</name>
</Teacher-Names>
.....


If i apply the Xpath API,  will it return a NodeList of  all element
inside  

<Teacher-Names>  


thanks
