Avoiding redeclaration for transactions in Xquery

Avoiding redeclaration for transactions in Xquery

Given:
let $name := '751-1500'
return xdmp:node-delete(doc(concat('/', $name, '.xml'))//foo);
let $name := '751-1500'
return xdmp:node-delete(doc(concat('/', $name, '.xml'))//bar);
let $name := '751-1500'
return xdmp:node-delete(doc(concat('/', $name, '.xml'))//baz);
How can I avoid having to redeclare $name?
