    <p>I am officially declaring myself as dumb !!! I'm quite good with regex but the javascript regex is getting on my nerves:</p> <p>I have following html string:</p> <pre><code>htmlString = '&lt;div class="aa"&gt;TextOne&lt;/div&gt;&lt;ul&gt;&lt;li&gt;one&lt;/li&gt;&lt;/ul&gt;'; </code></pre> <p>I need to get all that is inside the UL element based on the text that is inside the aa class div.</p> <p>I tried the following:</p> <pre><code>textItem = 'TextOne'; ulRegex = new RegExp('&lt;div class="aa"&gt;'+textItem+'&lt;/div&gt;&lt;ul&gt;(.*)&lt;/ul&gt;', "igm"); ul = ulRegex.exec(htmlString); </code></pre> <p>While writing this question i discovered an error (one tiny extra character) in my regex that didn't let it match but for all those looking for something specific - javascript / regular expression / html string / html substring - its working fine.</p> <p><strong>Edited</strong></p> <p>I'm thankful for all the additions to this - but there is one additional aspect i'm using regex - being that i am matching a text item which i am getting through a variable first for the regex pattern.</p> <p><strong>Solution</strong></p> <p>Having received a few hints and suggestions i came up with the following which may help someone else as well:</p> <pre><code>htmlString = '&lt;div class="aa"&gt;TextOne&lt;/div&gt;&lt;ul&gt;&lt;li&gt;one&lt;/li&gt;&lt;/ul&gt;'; textItem = 'TextOne'; tempdiv = $('&lt;div/&gt;'); tempdiv.html(htmlString); ul = tempdiv.find('div.aa:contains('+textItem+')').next('ul'); $('#res').append(ul); </code></pre> <p><a href="http://jsfiddle.net/sdXpJ/" rel="nofollow">http://jsfiddle.net/sdXpJ/</a></p> <p>The next ul is important because that solves the issue regarding nested ULs and any other regex based solution where i couldn't match a first level UL (having internal one or more Uls).</p>

    1. CODon't parse HTML with Regex, you might be able to make it work but don't go that route. Use an XML/HTML parser instead.

    2. COI'm confused a little bit. It seems you have a "working" regex. One small detail, use `.*?` instead of `.*` to match ungreedy. There is no need to use the `m` modifier. Also don't forget to add some `\s*` for sake of completeness

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
