This situation can be handled fairly easily using recursion to match opening and closing quotes.
I don't know if the regular expression engine in the text editor TextMate is the same as the one in Sigil. But the following regular expression will find a string consisting of an entire html element in TextMate.
<\?xml[^>]+>|<!DOCTYPE(?:[^\]]*]>|[^>]*>)|<[^/ >]+[^>]*/>|<(?<tagname>[^/ >]+)[^>]*>(?<!/>)(?<html>[^<]|<[^/ >]+[^>]*/>|<(?<tagname>[^/ >]+)[^>]*>(?<!/>)\g<html>*</\k<tagname+0>>)*</\k<tagname+0>>
example: take the following string of text.
<p>This is an <i>example</i> paragraph.</p><p>This is a second paragraph.</p>
If the cursor is at the beginning of the text, the regular expression will match
<p>This is an <i>example</i> paragraph.</p>. If the cursor is after the first < and not after the second <, it will match
<i>example</i>. If the cursor is after the second <, it will match
<p>This is a second paragraph.</p>
In other words, it matches the first opening html tag encountered with its appropriate closing tag. But it will only work on properly formatted html. For example, in this improperly formatted html string
<p>This is the first paragraph<p>This is the second paragraph</p>
it will not match the first paragraph because the first closing tag </p> is missing.
The regular expression can handle tags that close themselves like <p/> or <div/> or <link href="my.css" type="text/css" rel="stylesheet"/> or <a name="chap4" id="chap4"/>.
