使用 powershell 提取 zip 文件，读取文件，然后提取标签之间的值

Question

I am pretty new to scripting and I have been stuck on this problem.

I want to extract a zip file and in that zip file there is a xml file called file.xml which I need to extract information from.

The file is huge and I only need to extract info between two tags.

<Report name="result\_many fail" summary="20" yes=19 no="1" finished=20> 

I need to extract information between the tags name and finished and save it to a txt file. The txt file should look like this:

name result_many fail, summary 20, yes 19 , no  1, finished 20

The problem is that it unzips to the right destination folder but it doesn't save anything into the result.txt file. My txt file is always empty.

This is my code:

echo "unzipping file..."
powershell C:\path_to_zip_file -Destinationpath C:\path_to_to_destination_folder;
$Path = “C:\path_to_to_destination_folder\file.xml;”
Select-Xml -XPath '//Report[@finished]').Node.InnerText;
Set-Content -Path 'C:\path_to_to_destination_folder\result.txt'

@echo "done"

Could someone help me out?

Leaving aside incidental aspects of your question (seemingly calling from cmd.exe , the broken attempt to extract a ZIP archive, lack of a file argument to Select-Xml , lack of input to the Set-Content cmdlet):

$file = 'C:\path_to_to_destination_folder\file.xml'
(Select-Xml '//Report[@finished]' $file).
  Node.Attributes.ForEach({ $_.Name + ' ' + $_.Value }) -join ', ' |
    Set-Content -Path C:\path_to_to_destination_folder\result.txt
