Get path (windows style) from any type of text (error message, e-mail corps ...), quoted or not. THIS IS THE SINGLE LINE VERSION ! If you want understand how it work or edit it, go https://regex101.com/r/7o2fyy Relative path are not supported The goal is to catch what "Look like" a path. See the limitations UNC path and prefix path like //./], [//?/] or [//./UNC/] are allowed some url path like [file:///C:/] or [file://] are allowed Catch path quoted with ["] and [']. But these quotes are include with the catch Quoted path is not concerned by limitations Limitations : (only unquoted path) [dot] and [space] is allowed, but not in a row [dot+space] or [space+dot at end of file name isn't catched INSIDE A NAME FILE (or last directory if it is a path to a directory) : [comma] is not supported (it stop the catch) after a first [dot], any [space] stop the catch after a [space], catch is stoped if next character is not a [letter], [digit] or [-] so, double [space] stop the catch Compatibility compatible PCRE, PCRE2 AutoHotkey : don't forget to escape "%" in "`%" /!\ Powershell and .Net /!\\ : this regex need some modification to be interpreted by powershell. You have to replace each (?&CapturGroupName) by \k. Use this powershell code to do this replacement : ` $powershellRegex = @' [Put here the regex to replace (?&CapturGroupName) with \k] '@ -replace '\(\?&(\w+)\)', '\k' ` This example code must return : [Put here the regex to replace \k with \k]

Description

Capture parts of SCORM 2004 TIMEINTERVAL format

Format

P[yY][mM][dD][T[hH][nM][s[.s]S]]

where:

  • y: The number of years (integer, >= 0, not restricted)
  • m: The number of months (integer, >=0, not restricted)
  • d: The number of days (integer, >=0, not restricted)
  • h: The number of hours (integer, >=0, not restricted)
  • n: The number of minutes (integer, >=0, not restricted)
  • s: The number of seconds or fraction of seconds (real or integer, >=0, not restricted). If fractions of a second are used, SCORM further restricts the string to a maximum of 2 digits (e.g., 34.45 – valid, 34.45454545 – not valid). The character literals designators P, Y, M, D, T, H, M and S shall appear if the corresponding non-zero value is present. Zero-padding of the values shall be supported. Zero-padding does not change the integer value of the number being represented by a set of characters. For example, PT05H is equivalent to PT5H and PT000005H.

Example

P1Y3M2DT3H indicates a period of time of 1 year, 3 months, 2 days and 3 hours PT3H5M indicates a period of time of 3 hours and 5 minutes
