Is there a way to use Select-String to print the line number and the matched value (not the line)? - powershell

Question

I am using powershell to search several files for a specific match to a regular expression. Because it is a regular expression, I wan't to only see what I have programmed my regex to accept, and the line number at which it is matched.
I then want to take the matched value and the line number and create an object to output to an excel file.
I can get each item in individual select string statements, but then they won't be matched up with each other
Select-String -Path $pathToFile -Pattern '(?<={\n\s*Box\s=\s")14\d{3}(?=",)' |
Select LineNumber, Matches.Value
#Will only print out the lineNumber
Select-String -Path $pathToFile -Pattern '(?<={\n\s*Box\s=\s")14\d{3}(?=",)' |
Foreach {$_.matches} | Select value
#Will only print matched value and can't print linenumber
Can anyone help me get both the line number and the matched value?
Edit: Just to clarify what I am doing
$files = Get-ChildItem $directory -Include *.vb,*.cs -Recurse
$colMatchedFiles = #()
foreach ($file in $files) {
$fileContent = Select-String -Path $file -Pattern '(?<={\n\s*Box\s=\s")14\d{3}(?=",)' |
Select-Object LineNumber, #{Name="Match"; Expression={$_.Matches[0].Groups[1].Value}}
write-host $fileContent #just for checking if there is anything
}
This still does not get anything, it just outputs a bunch of blank lines
Edit: What I am expecting to happen is for this script to search the content of all the files in the directory and find the lines that match the regular expression. Below is what I would expect for output for each file in the loop
LineNumber Match
---------- -----
324 15
582 118
603 139
... ...
File match sample:
{
Box = "5015",
Description = "test box 1"
}....
{
Box = "5118",
Description = "test box 2"
}...
{
Box = "5139",
Description = "test box 3"
}...

Answer 1

Example 1
Select the LineNumber and group value for each match. Example:
$sampleData = #'
prefix 1 A B suffix 1
prefix 2 A B suffix 2
'# -split "`n"
$sampleData | Select-String '(A B)' |
Select-Object LineNumber,
#{Name="Match"; Expression={$_.Matches[0].Groups[1].Value}}
Example 2
Search *.vb and *.cs for files containing the string Box = "<n>", where <n> is some number, and output the filename, line number of the file, and the number on the box = lines. Sample code:
Get-ChildItem $pathToFiles -Include *.cs,*.vb -Recurse |
Select-String 'box = "(\d+)"' |
Select-Object Path,
LineNumber,
#{Name="Match"; Expression={$_.Matches[0].Groups[1].Value -as [Int]}}
This returns output like the following:
Path LineNumber Match
---- ---------- -----
C:\Temp\test1.cs 2 5715
C:\Temp\test1.cs 6 5718
C:\Temp\test1.cs 10 5739
C:\Temp\test1.vb 2 5015
C:\Temp\test1.vb 6 5118
C:\Temp\test1.vb 10 5139
Example 3
Now that we know that we want the line before the match to contain {, we can use the -Context parameter with Select-String. Example:
Get-ChildItem $pathToFiles -Include *.cs,*.vb -Recurse |
Select-String 'box = "(\d+)"' -Context 1 | ForEach-Object {
# Line prior to match must contain '{' character
if ( $_.Context.DisplayPreContext[0] -like "*{*" ) {
[PSCustomObject] #{
Path = $_.Path
LineNumber = $_.LineNumber
Match = $_.Matches[0].Groups[1].Value
}
}
}
