XML Parsing - XPath expression trying to access xml elements inside second for loop

Question

I have an XML file that I am trying to parse and store as objects so that I can persist them.

<key>Playlists</key>
<array>
    <dict>
        <key>Name</key><string>Library</string>
        <key>Master</key><true/>
        <key>Playlist ID</key><integer>1806</integer>
        <key>Playlist Persistent ID</key><string>29E12A03204E0722</string>
        <key>Visible</key><false/>
        <key>All Items</key><true/>
        <key>Playlist Items</key>
        <array>
            <dict>
                <key>Track ID</key><integer>1234</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1282</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1694</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1558</integer>
            </dict>
       </array>
    </dict>
    <dict>
        <key>Name</key><string>Music</string>
        <key>Playlist ID</key><integer>2687</integer>
        <key>Playlist Persistent ID</key><string>29E12A03204E072C</string>
        <key>Distinguished Kind</key><integer>4</integer>
        <key>Music</key><true/>
        <key>All Items</key><true/>
        <key>Playlist Items</key>
        <array>
            <dict>
                <key>Track ID</key><integer>1234</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1282</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1694</integer>
            </dict>
            <dict>
                <key>Track ID</key><integer>1558</integer>
            </dict>
       </array>
    </dict>

I'm having trouble accessing the second array. It keeps displaying track Id's from the first array in every playlist.

It is doing this for all the playlists I am trying to display.

Could anyone help me with this?

Change

NodeList tList = (NodeList)x.evaluate("/plist/dict/array/dict/array/dict", root, XPathConstants.NODESET);

to

NodeList tList = (NodeList)x.evaluate("array/dict", dict, XPathConstants.NODESET);

That doesn't seem to work. Still showing the same numbers in every playlist. – ariella123 Dec 06 '15 at 22:11
