info.plist - xmlstarlet does not return specified node

I am attempting to parse an info.plist (for an iOS app) using xmlstartlet. I'm doing this in OSX on a MacBook Pro. Here is my info.plist:

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

    <string>needs access to the calendar</string>

    <string>needs access to bluetooth</string>
    <key>UIStatusBarStyle</key>
    <string>UIStatusBarStyleLightContent</string>

    <key>XSLaunchImageAssets</key>
    <string>Resources/Media.xcassets/LaunchImages.launchimage</string>
</dict>
</plist>

Here is my xmlstarlet command:

xmlstarlet sel -t -m "/plist/dict[key='CFBundleVersion']" -v string ./Info.plist

Here is the output:

Any ideas why it's returning all 'string' nodes at that level?

Solution

You're matching dict and getting the value of string so it's returning all the strings in dict.

The check to see if there is a key element with the value CFBundleVersion doesn't do anything other than only select the dict if that's true.

Try selecting the key itself and then getting the value of the first following-sibling string...

xmlstarlet sel --net -t -m "/plist/dict/key[.='CFBundleVersion']" -v "following-sibling::string[1]" ./Info.plist

This will return:
