In a XML file with 100 lines of code, there is one string with a specific pattern that I want to find and write into a new text file.
What the string contains is unknown and can vary, but the pattern is the same. For example:
12hi34
99ok45
Those have in common that the length is 6 and element:
0-1: integers
2-3: characters
4-5: integers
Is there a way to use Powershell and write a script that can find the string that fit the pattern and export it in a text file?
I'm new to Powershell and scripting. Tried to Google the problem and stumbled upon Select-String, but that doesn't solve my problem. Hope some of you can guide me here. Thanks.
Edit: The string is outside the root element as some "free text". It is not a traditional XML file.
Assuming there's only one token of interest in the file, and that the letters are limited to English letters 'a' through 'z':
(Get-Content -Raw in.xml) -replace '(?s).*(\d{2}[a-z]{2}\d{2}).*', '$1' > out.txt
Note:
If no matching token is found, the input file's entire content is written to out.txt.
On Windows PowerShell > produces UTF-16LE ("Unicode") files by default (in PowerShell Core it is UTF-8 without a BOM); pipe to Set-Content out.txt -Encoding ... instead to create a file with a different encoding.
Get-Content -Raw reads the entire input file as a single string.
The -replace operator uses regular expressions (regexes) for matching - see this answer for more information.
(?s) at the start of regex makes . match newlines too.-creplace for case-sensitive matching.Collected from the Internet
