WIX Installer remove entry from XmlConfig element - wix

Question

How to delete the "DrawListAddin" from this list with WIX XmlConfig ?
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfString xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema- instance">
<string>ExplorerAddin</string>
<string>DrawListAddin</string>
<string>MyDataAddin</string>
</ArrayOfString>
Result should look like this
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfString xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema- instance">
<string>ExplorerAddin</string>
<string>MyDataAddin</string>
</ArrayOfString>
i try multiple settings but nothing work .. the last version looks like this. Searching for the correct item and than remove it. The XML file gets modified but no changes.
<util:XmlConfig Id='XmlSettingsRemove'
On="install"
File='[E3D31_INSTALL_DIR]DesignAddins.xml'
Node='element'
Action='delete'
VerifyPath="//*[\[]text() [\[]contains(.,'DrawListAddin')[\]][\]]"
ElementPath="//ArrayOfString"
Sequence='1'
/>
this code bring an error message that the node could not be found but the "/.." at the end explicit selects the parent correct
<util:XmlConfig Id='XmlSettingsRemove'
On="install"
File='[E3D31_INSTALL_DIR]DesignAddins.xml'
Node='element'
Action='delete'
VerifyPath="/ArrayOfString/string[\[]text()[\[]contains(.,'DrawListAddin')[\]][\]]"
ElementPath="/ArrayOfString/string[\[]text()[\[]contains(.,'DrawListAddin')[\]][\]]/.."
Sequence='1'
/>

just for review .. here is the solution with a embedded script .. i put some placeholder into the code like "DO_SOME_HERE" ..
<CustomAction Id="UnInstallUIFileSetProperty" Property="UnInstallUIFileExec" Value="[PLACE_YOUR_PATH_TO_XML_FILE_HERE]" />
<CustomAction Id="UnInstallUIFileExec" Script="vbscript" Execute='deferred' Impersonate='no' Return='ignore'>

on error resume next
c=Session.Property("CustomActionData")
n=c+"ADD_THE_XML_FILENAME_HERE"
Set x = CreateObject("Microsoft.XMLDOM")
x.async = False
x.load(n)
Set r = x.documentElement
Set l = r.getElementsByTagName("string")
For Each e In l
if InStr(e.text,"ENTER_SEARCHTEXT_HERE") then
e.ParentNode.removeChild(e)
end if
Next
if err.Number<>0 then
res=MsgBox("remove of addin failed: "+n)
else
x.Save(n)
end if

</CustomAction>
