Title Test Details Pattern Title
Expression
<[^>]*>
Description
HTML Pattern Matching PLEASE HELP /&lt;[^&gt;]*&gt;/ig The above pattern is only successful when html tag are simple (they don't include any javascript). This mean that the pattern will fail if something like this is within the tag &lt;input type=button value=test onclick='if(n.value&gt;5)do_this();'&gt;. It will not match the entire open n close sign. How do you write a pattern that will pass all these tag so that the pattern will match from the open to the close sign and not when it just see a &gt; within a '' or &quot;&quot;. &lt;input type=button onclick='if(n.value&gt;5)do_this();'&gt; not this &lt;br&gt; &lt;input type=button onclick=&quot;n&gt;5?a():b();&quot; value=test&gt; not this &lt;br&gt; &lt;input type=button onclick=&quot;n&gt;5?a(\&quot;OK\&quot;):b('Not Ok');&quot; value=test&gt; not this &lt;br&gt; &lt;input type=button onclick='n&gt;5' value=test onmouseover=&quot;n&lt;5&amp;&amp;n&gt;8&quot; onmouseout='if(n&gt;5)alert(\'True\');else alert(&quot;False&quot;)'&gt; not this &lt;br&gt; Any help would be greatly appreciate. Thanks a whole lot. Logan

Title Test Details Pattern Title
Expression
src[^&gt;]*[^/].(?:jpg|bmp|gif)(?:\&quot;|\')
Description
This expression will return the src (source) property of an image tag &lt;IMG&gt;. The source returned is limited to the file extensions supplied. It doesn't matter if the image is prefixed with '../' or 'http://..blah' or 'drive\path' or nothing. This expression could be modifed to return other sources or for the tags (ie &lt;BGSOUND&gt;, &lt;SCRIPT&gt;, etc.) depending on the file extensions given. I needed this to replace the source of images in a HTML page when I wanted to save the page to a local drive and keep the images intact. If anybody could modify this further to include only the &lt;IMG&gt; tag, I would appreciate the effort.
Matches
src=&quot;../images/image.jpg&quot; | src=&quot;http://domain.com/images/image.jpg&quot; | src='d:\w

Description
This RE and MatchEvaluator will remove everything from inside HTML font tags EXCEPT the color declaration. (For ex: allow users to upload HTML content to site without their font tags overridding the font styles set in the CSS, except for the ability to change the font color for special emphasis.) This works with color declarations using single quotes, double quotes, no quotes, color-names (red, black), Hex colors (#669933), and inline Style declarations inside a font tag. Does not work with inline Style declarations inside other tags like DIV, SPAN, or P (although it could be expanded to include those as well).
Matches
&lt;font size=5 color=black face=Arial&gt; | &lt;font style=&quot;font-family:arial;color:red&quot;&
Non-Matches
&lt;DIV style=&quot;font-family:arial;color:red&quot;&gt; | &lt;SPAN style=&quot;color:red&quot;&gt;
