Title Test Details Pattern Title
Expression
(\[[Ii][Mm][Gg]\])(\S+?)(\[\/[Ii][Mm][Gg]\])
Description
easy when you want to allow your users to post images, but in a controlled way. I used it like this (in php): $text = preg_replace("/(\[IMG\])(\S+?)(\[\/IMG\])/is", "<a href=\"\\2\" target=\"_blank\"><IMG SRC=\"\\2\" align=\"center\" height=\"100\" border=\"0\"></a>",$text); so whenever they use [img]http://www.foo.com/bleh.jpg[/img] it will be converted to <a href="http://www.foo.com/bleh.jpg" target="_blank"><IMG SRC="http://www.foo.com/bleh.jpg" align="center" height="100" border="0"></a> so you get a 100 pixels high picture, and when they click on it it opens in a new window... (to prevent users from posting huge pictures and stuff)
Matches
[IMG]http://bleh.jpg[/IMG] | [ImG]bleh[/imG] | [img]ftp://login:pass@bleh.gif[/img]
Non-Matches
<img src="bleh.jpg">

Title Test Details Pattern Title
Expression
<[a-zA-Z]+(\s+[a-zA-Z]+\s*=\s*("([^"]*)"|'([^']*)'))*\s*/>
Description
Matches a valid &quot;empty&quot; tag (has trailing slash). Note, if you run it against a string such as &lt;img src=&quot;test.gif&quot; alt=&quot;&lt;hr /&gt;&quot;&gt; it will indeed return a match. But, the match is not at character 1 like you'd suspect, but rather it's matching the internal &lt;hr /&gt;. If you look at the source of this tag (http://concepts.waetech.com/unclosed_tags/) you'll find a whoe suite of regex's for matching html tags. Using them you could feasibly step though a document and avoid this mismatch as the outer tag would match *in totality* and you'd completely skip this inner match.
Matches
<img src="test.gif"/>
Non-Matches
<img src="test.gif"> | <img src="test.gif"a/>

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
Non-Matches
src=&quot;../images/image.tif&quot; | src=&quot;cid:value&quot;

Description
This pattern can intercept img like < img src="src1" alt="alt1"> or < img alt="alt1" src="src1"> or < img src="src1"> or < img src="src1" width=3 height=4> then values of src can be found in $5 or $8, the value of tag alt can be found in $3 or $10.

Title Test Details Extract "src" attr from EMBED tag (for Flash)
Expression
(?<=<embed\s[^<>]*?src\s*?=\s*?\x22)[^<>]*?(?=\x22[^<>]*?>)
Description
This pattern will extract the "src" attribute of an EMBED tag. I created it for extracting the URI of an Adobe Flash animation from some HTML, but of course it would work for more general purposes. Don't forget to turn on case insensitivity.
Matches
In &lt;embed src="somefilename.swf" width="550" height="400"&gt; matches "somefilename.swf"
Non-Matches
Doesn't match the surrounding HTML.

Title Test Details Script Block Parser
Expression
<script(?:(?:.*(?<src>(?<=src=")[^"]*(?="))[^>]*)|[^>]*)>(?<content>(?:(?:\n|.)(?!(?:\n|.)<script))*)</script>
Description
This one enables you to parse well-formed script tags to get both the src value and the block content, if specified. I'm using this one in some AJAX where I get script blocks back in a text reponse and need to parse them and add them to the DOM so they get processed.
Matches
<script type="text/javascript" src="Test.js"></script>
Non-Matches
<script src=Test.js></script>

Title Test Details Detect Javascript
Expression
<script.*/*>|</script>|<[a-zA-Z][^>]*=['"]+javascript:\w+.*['"]+>|<\w+[^>]*\son\w+=.*[ /]*>
Description
Matches any opening or closing script tags, inline javascript: tags, inline on<function> (ex: onClick) tags. MATCHES: <a href="javascript:alert('test0');"> <a href='javascript:alert("test1");'> <a href="#" onClick="alert('test2');" /> <script language="javascript" src="somewhere.js"> <script language="javascript" src="somewhere.js" /> <script> </script>
Matches
<a href="javascript:alert('test0');"> or <a href="#" onClick="alert('test');" /> etc...
Non-Matches
This should not appear because in javascript: you can use the < operator or the > operator.

Title Test Details Capture HTML Tags
Expression
<font[a-zA-Z0-9_\^\$\.\|\{\[\}\]\(\)\*\+\?\\~`!@#%&-=;:'",/\n\s]*>
Description
This expression will capture font tags(or any other HTML tag if you change the word font in the expression) with parameters and stop at the closing font tag bracket. The only keyboard characters it will not find between the starting and ending bracket are additional brackets. So for example if you are looking for image tags it will not find <img src="..." alt=">My Picture<"> due to the nested brackets. When I allowed nested brackets like this the expression did not always return only the tag I was looking for. Sometimes it returned additional tags at the end so I suggest staying away from brackets in alt text and anywhere else you may be allowed to do it.
Matches
<font color="#006666">, <font face="arial" style="font-size: 11pt">
Non-Matches
<font, </font>, <font <>

Title Test Details Identify relative urls
Expression
(src|href|action)\s*=\s*('|"|(?!"|'))(?!(http:|ftp:|mailto:|https:|#))
Description
After hitting little snags through the years here is a [WIP] for replacing relative links. Notice that it considers whitespace between the src,href and the equal sign, it also considers the links may not have any quotes around them. It negates urls that start with http,ftp,link anchors, https and mailto.
Matches
href=" src = "pa href='../
Non-Matches
href="mailto: href="mailto: src='ftp:
