Yet another one RegExp request

[mjolnirmarkiv]

Hello,

Have been thinking about this for a while, so decided to seek for help.

I have the following string: "...<tag>1</tag>...<tag>2</tag>...<tag>3</tag>...", which I need to test if all text within <tag> matches certain criteria, e.g. it's a number "\d+". The trick is 1) I need the entire match to fail if only one instance of the text between <tag> doesn't match "\d+"; 2) I need the string to match if there's no <tag>.

E.g.:

- "...<tag>1</tag>...<tag>2</tag>...<tag>3</tag>..." matches.
- "...<tag>a</tag>...<tag>2</tag>...<tag>3</tag>..." fails.
- "..." matches.

Thanks!

This?

Local $aTest = [ _
    "...<tag>1</tag>...<tag>2</tag>...<tag>3</tag>...", _
    "...<tag>1</tag>...<tag></tag>...<tag>3</tag>...", _
    "...<mytag>""1""</mytag>...<yourtag></yourtag>...<ourtag>3</ourtag>...", _
    "...nothing important here...", _
    "...<tag>a</tag>...<tag>2</tag>...<tag>3</tag>..." _
]

For $s In $aTest
    ConsoleWrite($s & (StringRegExp($s, '<tag>\D*</tag>') ? ' fails' : ' matches') & @LF)
Next

Not quite, actual criteria I need to check is ".*?(.*?\)" i.e. "text text (text text)", I've replaced it with "\d+" for the simplicity. You inverted criteria with "\D*", so I'm not sure how I can do the same with ".*?(.*?\)".

But you gave me an idea, this works: "<tag>(?(?=[^<]+?\h\([^<]+?\))(*FAIL)|(*ACCEPT))</tag>"... unless there're easier ways to do it?

mjolnirmarkiv, could you give us some examples of matching and not matching strings ?

Sorry

Here're couple of examples of matched strings:

text <‍tag>text (text)<‍/‍tag> text <tag>text (text)</tag> text.
text text text text text.

And here's failed string:

text <‍tag>text<‍/‍tag> text <tag>text (text)</tag> text.

In other words, no words in brackets within <tag> = fail.

 

But nevermind, jchd gave me an idea, so I consider this one closed. Following regexp should work: "<tag>(?![^<]+?\h\([^<]+?\))" -- I just need to invert its logic.

You have zero width white spaces Joiners in your strings.  I dont know how much that will muck up the water, but a stringstripws may be helpful wont do anything, maybe delete all the 8205s from an ascii array or stringreplace?

boththose, yeah, I know, I've included "\x{200d}" in the regexp.
