Extracting specific data from a string with regex and Powershell

Question

I want to extract from this string

blocked-process-report process id=\"process435d948\" taskpriority=\"0\" logused=\"0\" waitresource=\"RID: 7:1:

Answer 1

The quick and dirty:

$found = $string -match '.*spid="(\d+)".*'
if ($found) {
    $spid = $matches[1]
}

where $string is your above mentioned string. This would match any string that has spid="somenumberhere", and make the number into a matched group, which you can extract using $matches[1].

Answer 2

Save that as, say $string.

Then do

$string -match 'spid="(\d+)"'

If there is a match, the value you want will be in $matches[1]
