Your title says XML, but that text is not valid XML. If you are open to solutions other than a regex... Getting a list of XML elements in a document Re: Retrieving a List of XML Tag Names from Given File	[reply]

Tags? Are you using the right terminology? You asked for the following output: `my @tags = ( '<text>', '<Find>', '</text>', '<find>', );` [download] I'm guessing that's not what you want, but I'd rather not guess what you want wrong, so I'll wait for clarification. PS — That's not valid XML.	[reply] [d/l]

That is not even remotely like valid XML, but anyway... You can try this (ignoring CDATA sections, but including other weird stuff, like the XML declaration): `@tags = grep defined, $xml =~ /<!--.?-->\|(<(?>[^"'>]+\|'[^']'\|"[^"]" +)>)/sg;` [download] And of course, you'll have some cleaning up to do now, because the output is very coarse. As a first step into parsing this content, you can use the above regexp in split: `@tokens = split /<!--.?-->\|(<(?>[^"'>]+\|'[^']'\|"[^"]")>)/s, $xml;` [download] which will return a list of text and tags. Comments will be thrown away.	[reply] [d/l] [select]

To echo what others are saying ... this is clearly an XML file, so you want to use an XML package. There are several of these. There are “simple parsers,” and there are also much more sophisticated ones ... including packages that let you write (industry standard) “XPath expressions” that can search an entire XML structure for you, with no special coding (on your part) at all. “`TMTOWTDI`™” ... and the choice is yours.
