let string = "The problem is, if the page contains a PDF linked to another page (not my own website), example https://othersite.example.com/whatever.pdf, it becomes https://othersite.example.com/whatever_SPANISH.pdf which isn't valid on other people's sites. I want to ignore offsite links and only change URLs on my site.
So what I would like to do is look for the string: https://example.com/documents/en/whateverfilename.pdf and pull that file name out and change it to https://example.com/documents/es/whateverfilename_SPANISH.pdf (Switching the en to es and also appending the _SPANISH to the end of the PDF filename.
";
let substitution = "$1es$2_SPANISH.pdf";
// result will be a String with the substituted value
let result = regex.replace_all(string, substitution);
println!("{}", result);
}
