'Pure regex solution to remove entire text after a certain part of text (in a plist file)

I've looked through all sorts of questions here, but couldn't find an answer to mine. I want to remove the entire text that follows a particular text part. Not within a string, but really the whole following text!

Here’s an example of a plist (it's really just a simple example. Normally the plist is much longer, but this should have no relevance for the question or answer):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>WFWorkflowActions</key>
    <array>
        <dict>
            <key>WFWorkflowActionIdentifier</key>
            <string>is.workflow.actions.comment</string>
            <key>WFWorkflowActionParameters</key>
            <dict>
                <key>WFCommentActionText</key>
                <string>Comment</string>
            </dict>
        </dict>
    </array>
    <key>WFWorkflowClientRelease</key>
    <string>3.0</string>
    <key>WFWorkflowClientVersion</key>
    <string>1030.14</string>
    <key>WFWorkflowIcon</key>
    <dict>
        <key>WFWorkflowIconGlyphNumber</key>
        <integer>59771</integer>
        <key>WFWorkflowIconStartColor</key>
        <integer>463140863</integer>
    </dict>
    <key>WFWorkflowImportQuestions</key>
    <array/>
    <key>WFWorkflowInputContentItemClasses</key>
    <array>
        <string>WFAppStoreAppContentItem</string>
        <string>WFArticleContentItem</string>
        <string>WFContactContentItem</string>
        <string>WFDateContentItem</string>
        <string>WFEmailAddressContentItem</string>
        <string>WFGenericFileContentItem</string>
        <string>WFImageContentItem</string>
        <string>WFiTunesProductContentItem</string>
        <string>WFLocationContentItem</string>
        <string>WFDCMapsLinkContentItem</string>
        <string>WFAVAssetContentItem</string>
        <string>WFPDFContentItem</string>
        <string>WFPhoneNumberContentItem</string>
        <string>WFRichTextContentItem</string>
        <string>WFSafariWebPageContentItem</string>
        <string>WFStringContentItem</string>
        <string>WFURLContentItem</string>
    </array>
    <key>WFWorkflowMinimumClientVersion</key>
    <integer>900</integer>
    <key>WFWorkflowMinimumClientVersionString</key>
    <string>900</string>
    <key>WFWorkflowTypes</key>
    <array>
        <string>NCWidget</string>
        <string>WatchKit</string>
    </array>
</dict>
</plist>

I want to remove everything including and after:

</array>
    <key>WFWorkflowClientRelease</key>

All line breaks/new lines must be kept.

The result would then look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>WFWorkflowActions</key>
    <array>
        <dict>
            <key>WFWorkflowActionIdentifier</key>
            <string>is.workflow.actions.comment</string>
            <key>WFWorkflowActionParameters</key>
            <dict>
                <key>WFCommentActionText</key>
                <string>Comment</string>
            </dict>
        </dict>

I even found a way to find a solution, but for that I had to remove all new lines, which is not desired. I first used \n. Than I replaced </array><key>WFWorkflowClientRelease</key> with lrtxplqw and then removed everything after and including lrtxplqw with lrtxplqw.*$. In this very awkward way I managed to have everything removed including and after lrtxplqw. But the solution is not satisfactory, because the line breaks/new lines all have to be kept.

I would also be happy to remove the first part, which would be:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>WFWorkflowActions</key>
    <array>

The final result would look like this:

<dict>
            <key>WFWorkflowActionIdentifier</key>
            <string>is.workflow.actions.comment</string>
            <key>WFWorkflowActionParameters</key>
            <dict>
                <key>WFCommentActionText</key>
                <string>Comment</string>
            </dict>
        </dict>

You may use

^[\s\S]*?<array>|</array>\s*<key>WFWorkflowClientRelease</key>[\s\S]*

See the regex demo.
