matching many numbers

"1b4c6f8" -match ("\d")

I expected 4 matches (as I do get in ‘regular’ .net) but $matches only returns one.

What is the syntax for multiple matches?

thanks!

do you want this?

([char[]]“1b4c6f8” -match “\d”).Count

No, I need the values. My actual expression is more complex. I’m scrapping an HTML document.
I want a collection of all the matches.
The simple example should produce a collection with 4 numbers

I found this tip from Keith Hill. It’s from 2007 so there may be another way by now, but this works. ([regex]’\d’).matches(“a1b2c3d4e5”) | Foreach { $.value }

That first solution posted should work, if you just get rid of the ().count:

[char[]]“1b4c6f8” -match "\d"

Thanks a million!
I have a ‘page’ of text and I’m looking for a list of ‘WINNER OF THE XXX…’ embedded in HTML
Smatches[0] contains the page.

([regex]’(WINNER&nbsp;OF.*(?=</div>))’).matches($matches[0]) | Foreach { $
.value }

This works perfect. Is there a solution that uses -match?

I don’t think so.
This is a part of the about_comparison_operators:
[quote] -Match
Description: Matches a string using regular expressions.
When the input is scalar, it populates the
$Matches automatic variable.
Example:


PS C:&gt; “Sunday” -Match “sun”
True

PS C:&gt; $matches
Name Value
---- -----
0 Sun

PS C:&gt; “Sunday”, “Monday” -Match “sun”
Sunday[/quote]
