Refactor EL expressions in JSPs

Question

I have many JSP files with EL expressions of the form ${foo.bar.baz.phleem1}, ${foo.bar.baz.phleem2} etc. (the first two or three segments are equal). To reduce EL lookups I am in the process of refactoring these pages:

Source:

<c:out value="${foo.bar.baz.phleem1}" />
<c:out value="${foo.bar.baz.phleem2}" />
<c:out value="${foo.bar.baz.phleem3}" />

After refactoring:

<c:set var="baz" value="${foo.bar.baz}" />
<c:out value="${baz.phleem1}" />
<c:out value="${baz.phleem2}" />
<c:out value="${baz.phleem3}" />

I know I can do most of this with searching / replacing, but it feels unsafe as it ignores code structure.

Is there any support for this type of refactoring in either Eclipse or IntelliJ Idea?

Maybe you can use the nxml-mode in emacs. (i don't tested it) There are some functions like nxml-up-element. I bet you can create a powerful macro. But i think its more easy to grep the code and do it manually.
