PowerShell文本拆分问题：如何从TXT文件提取Brackets版本信息

Hey there! Let's get that "Release 1.11.6" string extracted smoothly. You were on the right track with Where-Object—here's how to finish the code and get exactly what you need:

Option 1: Split by Delimiter #

This is straightforward since your text uses # as a clear separator:

Get-Content -Path thisfile.txt | 
    Where-Object { $_ -match '^Brackets#' } | # Filter lines starting with "Brackets#"
    ForEach-Object { ($_ -split '#')[1] } # Split the line by # and grab the 2nd element (index 1)

Breakdown: #

• ^Brackets# uses a regex anchor (^) to ensure we only match lines that start with "Brackets#" (avoids accidental matches elsewhere in the text).
• Splitting the line with -split '#' turns it into an array like ["Brackets", "Release 1.11.6", "Path-to-Brackets"]—index 1 is your target value.

Option 2: Regex Capture Group #

If you prefer a more flexible approach (great if your formatting might vary slightly):

Get-Content -Path thisfile.txt | 
    Where-Object { $_ -match '^Brackets#(.*?)#' } | # Capture text between the first two #s
    ForEach-Object { $matches[1] } # Extract the captured group

Breakdown: #

• The regex ^Brackets#(.*?)# captures everything between the first # after "Brackets" and the next #. The (.*?) is a non-greedy match, so it stops at the first subsequent #.
• $matches[1] pulls out the content captured by the parentheses.

Quick One-Liner (if only one matching line exists) #

If you’re sure there’s only one line starting with "Brackets#" in the file, you can simplify it further:

(Get-Content thisfile.txt | Where-Object { $_ -match '^Brackets#' }) -split '#' | Select-Object -Index 1
