Aside from continuing the line at the foreach instead of the { ?

Would this site help? [https://regex101.com/](https://regex101.com/)

You could do something like this

```
cls
$input = @'
temp1.txt: file not found \xyz\ not found \123\
temp2.txt: text \ABC\ is here
temp2.txt: NUM \999\ yes \FIRST\
'@ -split "`r`n"

$input | ForEach-Object {
    $file = ($_ | Select-String -Pattern "^(.*?):").Matches.Groups[1].Value
    ($_ | Select-String -Pattern "\\.*?\\" -AllMatches).Matches.value | ForEach-Object {
        [pscustomobject]@{
            File = $file
            Path = $_
        }
    }
}
```

**Results:**

```
File Path   
---- ----   
temp1.txt \xyz\  
temp1.txt \123\  
temp2.txt \ABC\  
temp2.txt \999\  
temp2.txt \FIRST\
```

You should use the pre tags to format your code so it is readable.

Get-Content is for getting the content of an item, not a variable. Additionally [pscustomobject] is not a variable, it is a way to create a custom powershell object.

The result of this code

```
$input = "D:\Temp\all.txt"
$output_file = "D:\Temp\del.txt"
Get-Content $input |
 ForEach-Object {
    $file = ($_ | Select-String -Pattern "^(.*?):").Matches.Groups[1].Value
    ($_ | Select-String -Pattern "\\.*?\\" -AllMatches).Matches.value |
     ForEach-Object {
        [pscustomobject]@{
            File = $file
            Path = $_
        }
     }
}
```

Is custom object being generated that contain the data you desire. Those object are sent to the pipeline and then take the Out-Default when the pipeline end with no other out alternative provide. If you want to output those object to a file, you just specify that in the pipeline.

For Example to output to a text file

```
$input = "D:\Temp\all.txt"
$output_file = "D:\Temp\del.txt"
Get-Content $input |
 ForEach-Object {
    $file = ($_ | Select-String -Pattern "^(.*?):").Matches.Groups[1].Value
    ($_ | Select-String -Pattern "\\.*?\\" -AllMatches).Matches.value |
     ForEach-Object {
        [pscustomobject]@{
            File = $file
            Path = $_
        }
     }
} | Out-File -FilePath $output_file
```

Or to output to a CSV file

```
$input = "D:\Temp\all.txt"
$output_file = "D:\Temp\del.txt"
Get-Content $input |
 ForEach-Object {
    $file = ($_ | Select-String -Pattern "^(.*?):").Matches.Groups[1].Value
    ($_ | Select-String -Pattern "\\.*?\\" -AllMatches).Matches.value |
     ForEach-Object {
        [pscustomobject]@{
            File = $file
            Path = $_
        }
     }
} | Export-Csv -Path $output_file -NoTypeInformation
```
