| I have no idea how to do this with AHK, but this site lets you create RSS feeds for websites that don't offer feeds. |

| You could UrlDownloadToFile the web page, then, assuming there is some sort of identifier around the info you are looking for, pull the text from the file with a RegExMatch or something? |

1. Do a View Source of the webpage
2. Search your target text in the source
| Code: | <p class="MsoNormal" style="MARGIN: 0pt"><a name="OLE_LINK4"></a><a name="OLE_LINK3"></a><a name="OLE_LINK1"><span style="mso-bookmark: OLE_LINK3"><span style="mso-bookmark: OLE_LINK4"><font face="Arial" size="3"><span style="FONT-SIZE: 12pt; FONT-FAMILY: Arial">A303; A36, M4, A419, A338, A346, A30, A354, A342, A360, A350, B390, A429, B4040, Swindon and Trowbridge areas.</span></font></span></span></a></p>
<span style="mso-bookmark: OLE_LINK4"></span><span style="mso-bookmark: OLE_LINK3"></span><span style="mso-bookmark: OLE_LINK1"></span>
<p class="MsoNormal" style="MARGIN: 0pt; TEXT-ALIGN: center" align="center"><font face="Arial" size="3"><span style="FONT-SIZE: 12pt; FONT-FAMILY: Arial"> </span></font></p>
|
3. Find the smallest unique html before and after your target, then use something like this:
| Code: | ; BEWARE! Both RegEx and AHK need certain escape sequences!
;
; http://www.autohotkey.com/docs/commands/_EscapeChar.htm
; http://www.autohotkey.com/docs/misc/RegEx-QuickRef.htm
;
before := "4""><font face=""Arial"" size=""3""><span style=""FONT-SIZE: 12pt; FONT-FAMILY: Arial"">"
after := "<"
; "(.*)" is regex for: return anything in match variable as array
pattern := before . "(.*)" . after
URLDownloadToFile, http://www.safetycameraswiltshire.co.uk/mobile.asp, %A_ScriptDir%\html.tmp
FileRead, aFile, %A_ScriptDir%\html.tmp
RegExMatch(aFile, pattern, match)
MsgBox % match1 |
disclaimer: not tested, but should work

To prevent having to escape and thus easier changable in the future, you can use this: (not tested)
| Code: | | pattern := "\Q" . before . "\E(.*)\Q" . after . "\E" |
