Question

I am searching through a large codebase in Eclipse, using its RegEx search functionality. I need to find <script> tags that do not have a src attribute. I am new to RegEx, but have been able to hack something together:

^.*(^<script(?!.*src).*)$

This matches the tags I am looking for, but only if there is nothing on the line before the <script> tag. If there are spaces or anything, it doesn’t match.

Matches Correctly:

<script type="text/javascript">

Does Not Match:

      <script type="text/javascript">

How can I modify my expression so that it matches in any part of the line?

I’ve also tried prepending ^, \s*, [ ]*, and (?x) with no success.

Answer 1

Safe way would be to use regex pattern (<script\b(?![^>]*\bsrc=)[^>]*>)
