This solution isn't quite what I was looking for. It is close but it isn't
setup to set a property from a XML file value. The 2nd answer points to MSI
Extensions which is 2 years old and has a TON of other actions in the library.
What I am looking for is an extension or action that does this
<Property Id="MY_PROPERTY" Secure="yes" Value="0">
<util:XmlSearch Id="MySearch" File="MyXMLFile.XML"
XPath="substring-before(substring-after(/Root/node/node[\[]1[\]]/@Value,".bp"),".xml")"/>
</Property>
Where Value = "d26s30c198.bp41441001.xml"
And MY_PROPERTY would equal "41441001"
