I have an app that downloads thousands of XML files every night. Many of these have small errors ( they come from an encrypted source ) that Im trying to clean up before I parse them. Each file is checked line by line for noise. If I have n possible tags in a file with a different list of attributes for each, is there a regex that could be used to look for missing attributes? IE if I have <cat tail='text' meow='text'/> and <dog tail='text' bark='text'/> can I find instances of 'cat' that don't have 'meow' without discarding 'dog' entries? (assume that each line in the file is single XML statement (IE its closed)) and tags aren't nested.)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
