Only if you store it in a variable that's in scope where you want to
use it elsewhere, but...

it sounds like you just need a key:

<xsl:key name="inactiveTabByName" match="inactiveTab" use="@name"/>

then to get the @ID for a given name (say 'Email') you would use:

select="key('inactiveTabByName', 'Email')/@ID"
