How to compare two HTML file content in powershell,
I have two URLs( actual website URL and same HTML file is stored in azure storage account), these URLs need to compare and if any changes found then I need to update my storage account with new HTML.
Uploading is working fine for me. But comparison is not happening.

Do you care about what has changed? HTML is a structure. Are there changed in the HTML tags that matter or are you interested in the values within certain tags?
Or are you interested in finding out, for example, that there another inconsequential space somewhere in the HTML?
You will want to do something similar to the following:
$myVar = Compare-Object (Get-Content file1.html) (Get-Content file2.html)
Then have an if-else that does the upload if the value of $myVar is not null. i.e. if it's null the files match and nothing should be done.
I tried with the below sample, but it doesnt work for me.
(Invoke-webrequest -URI "https://www.google.com/index.html").Content > $filename1
(Invoke-webrequest -URI "https://{storage_account_url}/terms_and_conditions.html").Content > $filename2
Compare-Object (Get-Content $filename1) (Get-Content $filename2)
Try:
$filename1 = "c:\temp\file1.txt"
$filename2 = "c:\temp\file2.txt"
Invoke-webrequest -URI "https://www.w3.org/Style/CSS/Test/CSS3/Selectors/20020115/html/static/index.html" -OutFile $filename1
Invoke-webrequest -URI "https://www.w3.org/Style/CSS/Test/CSS3/Selectors/20020115/html/static/index.html" -OutFile $filename2
$result = Compare-Object (Get-Content $filename1) (Get-Content $filename2)
$null -eq $result
The result for this should be true - we are checking the same static page so it should be exactly the same - make sure you are testing against static pages and don't use the google homepage as that is not a static page - the metadata changes in each response.
