PowerShell RegEx match all possible matches

Question 1

I have the following script which includes some RegEx to capture specific information on this site.

$Top40Response = Invoke-WebRequest -UseBasicParsing -Uri 'https://www.radioinfo.com.au/knowledge/chart'

$Top40Response.Content -match '<td\Wclass="twRank">[\s\S]+artist">([^<]*)'
$matches

$Top40Response = Invoke-WebRequest -UseBasicParsing -Uri 'https://www.radioinfo.com.au/knowledge/chart'

$Top40Response.Content -match '[\s\S]+artist">([^<]*)'

$matches

This is matching the last ‘artist’. What I want to do is make this so it will run through and match every artist on this page in order top to bottom.

Question 2

PowerShell’s -match only returns first match. You have to use Select-String with -AllMatches parameter or [regex]::Matches.

Select-String:

$Top40Response = Invoke-WebRequest -UseBasicParsing -Uri 'https://www.radioinfo.com.au/knowledge/chart'

$Top40Response.Content |
    Select-String -Pattern '<td\s+class="artist">(.*?)<\/td>' -AllMatches |
        ForEach-Object {$_.Matches} |
            ForEach-Object {$_.Groups[1].Value}

$Top40Response = Invoke-WebRequest -UseBasicParsing -Uri 'https://www.radioinfo.com.au/knowledge/chart'

$Top40Response.Content |

Select-String -Pattern '(.*?)<\/td>' -AllMatches |

ForEach-Object {$_.Matches} |

ForEach-Object {$_.Groups[1].Value}

[regex]::Matches:

$Top40Response = Invoke-WebRequest -UseBasicParsing -Uri 'https://www.radioinfo.com.au/knowledge/chart'

$Top40Response.Content |
    ForEach-Object {[regex]::Matches($_, '<td\s+class="artist">(.*?)<\/td>')} |
        ForEach-Object {$_.Groups[1].value}

ForEach-Object {$_.Groups[1].value}
