    copied!<p><strong>The end aim</strong>... to retrieve a group of DIVs with specific attributes/values and update the element type and manipulate the attribute and value...</p> <p>I'd like to use RegEx to test the following <strong>scenario</strong> (I believe is correct based on the above aim)</p> <ul> <li>for each opening DIV</li> <li>that contains an <code>attribute-to-check</code> attribute <ul> <li>The attribute may or may <em>not</em> be the first attribute</li> </ul></li> <li>that has a value containing <code>value-contains</code> <ul> <li>The value may or may <em>not</em> be the first value in the attribute (allowing for future extensions)</li> </ul></li> <li>find <strong>its</strong> closing DIV <ul> <li>This DIV itself may contain other DIVs - <strong>including</strong> other DIVs that will also be matched</li> </ul></li> </ul> <p>So what have I <strong>tried</strong>? ...Using the test script:</p> <pre><code>&lt;p&gt;test1&lt;/p&gt; &lt;DIV attribute-to-check='notvalid'&gt; test2 &lt;/DIV&gt; &lt;p&gt;test3&lt;/p&gt; &lt;DIV attribute-to-check='value-contains:2012-12-12' class='test4'&gt; test5 &lt;/DIV&gt; &lt;p&gt;test6&lt;/p&gt; &lt;DIV attribute-to-check='value-contains:2012-01-01' class='asd'&gt; test6 &lt;/DIV&gt; &lt;p&gt;test7&lt;/p&gt; </code></pre> <p>I've got as far as the following RegEx...</p> <pre><code>&lt;?DIV.*?attribute-to-check='value-contains:.*?&gt;(.*?)&lt;/DIV&gt; </code></pre> <p>BUT this brings back </p> <pre><code>string 1: "&lt;DIV attribute-to-check='notvalid'&gt;test2&lt;/DIV&gt;test3&lt;DIV attribute-to-check='value-contains:2012-12-12' class='test4'&gt;test5&lt;/DIV&gt;" string 2: "&lt;DIV attribute-to-check='value-contains:2012-01-01' class='asd'&gt;test6&lt;/DIV&gt;" </code></pre> <p>I suspect it's bringing back <code>test2</code> in string1 as this has an opening div with the attribute-to-check <em>but</em> the value is notvalid? so I'm wondering if I'm getting the first DIV then any number of characters until it locates <em>any</em> other <code>attribute-to-check='value-contains:</code> and then the closing DIV after that? </p> <p>I am struggling to navigate from this point and would appreciate any helpers from the community :)</p> <p>Thanks Dylan</p>
