Help with a regular expression

[PaulStat]

I'm wanting to scan through an xml file and store the names of tags I've found in a list

The xml tags take the format

<tag:name param1="" param2=""></tag:name>

I'm just wanting to match the first part of the tag i.e. <tag:name

I've tried writing a re pattern which is

tag_re = "([<]+)([^?]+)((?:[\s])$)"

But it doesn't return any matches, what have I done wrong?

Don't technically need regex. Can use a search method to find everything between 'x' and 'y'...

But I don't know what x and y is, as I said I don't want the entire <tag:name param1="" param2=""> just <tag:name

You'll need to loop through the text and put it all into an array to print it out. foreach etc... though I am sure if you google around for

"find substring in string" you'll find some code that does it all for you. or "all substrings in text file" something like that.

(?<=<tag[\w|\d]+(?= )

dont use any spaces in the tag names.

OK this is for javascript but what about:

\b<[a-z]+:\w+\b

so from beginning of line match < then 1 or more lowercase characters, then a : then another word, then the end of the line.

though depending on the language, can't you use the XML xpath to get what you need?
