Question

I need to parse a lot of html files in order to know which ones contain specific text within title tag.

Let’s suppose that titles are

file1.htm
<title>100 text other text</title>
file2.htm
<title>text 100 text other text</title>
file3.htm
<title>text 1000 text other text</title>
file4.htm
<title>text one hundred text other text</title>

Following my example I need to find files name that contain 100 or one hundred, that is files 1,2 and 4.

My problem is that I don’t know how to write regular expression

gci "c:\my_folder" | ? {$_.extension -eq ".htm"} | 
select-string -pattern '<title>*100*</title>' |
Select-Object -Unique Path

Please note, if this may be important for regexp, that title tag is not at the beginning of a row but in the middle.
Thanks in advance.

Answer 1

This should do it.

^.*<title>(.*(100|one\shundred)[^0].*)?</title>.*$
