Checking if parent node has specific child

Question

I need to find the parents in an XML file which contain a specific tag, and then need to parse the strings from those parents and their children into a Java object, or array (could also use some advice on the best way to store the XML info as strings).

<task>
    <task id=483492>
    <project id=484383>
        <date>2003/23/03</date>
    <name> project name example </name>
</task>
<task>
    <task id=483492>
    <name> task name example </name>
</task>
<task>
    <task id=483492>
    <project id=484383>
        <date>2003/23/03</date>
    <name> project name example </name>
</task>
<task>
    <task id=483492>
    <project id=484383>
        <date>2003/23/03</date>
    <name> project name example </name>
</task>
<task>
    <task id=483492>
    <name> task name example </name>
</task>

So, if a <task> parent has a <project> child, I need to put the data from each <task>'s children into some kind of list/array/object.

Thanks in advance everyone.
