Find a string between html tags in Powershell

Question

I'm trying to write a Powershell script that will pull out a string between two HTML tags within an HTML file. I don't know what the value will be, but I know what tags need to be searched. Additionally, I know that the tags do not always appear at the start of a line (i.e., they can be in the middle of a line of text). Finally, I also know that the tags and the string between them will never break across a line.

I have the path of the file stored in a variable

$filePath = "C:\Path\file.html"

I'm trying to find any value between <h6> and </h6> and store those values in an array.

Try

$myarray = gc $filepath | 
% { [regex]::matches( $_ , '(?<=<h6>\s+)(.*?)(?=\s+</h6>)' ) } | 
select -expa value

This remove starting and trailing spaces if any. If you need also this spaces remove \s+ from the regex pattern

Perfect! After posting this I played more with my regex and I almost had it like you have. One last question: What does the select -expa value do?

@EustaceMonk You can try the command without pipe to select -expa value and then try with pipe to select value to understand the difference. testing it is better than my english ;)

I don't see a difference between using select -expa value and leaving that completely off. I do see the difference when using just select value.

@EustaceMonk Without pipe to select -expa value retuns all matchinfo. pipe to select value return an array of pscustomobject. pipe to select -expa value return an array of string
