We have a script that we are using that I believe is using regular
expressions (which I am very unfamiliar with) to pull data from a web page
source. The data is temperatures,
but if the temperatures are below zero, the minus sign is not pulled even
though it is on the website, just the number is pulled.

I have copied and pasted what I believe to be the relevant portions on the
VBA below, but if needed, I can post the entire script.

Many thanks!

For Each c In rng
sURLdate = Format(c.Value2, "yyyy/m/d")
c.Offset(0, i + 1).Value = RegexMid(myStr, sURLdate, "bl gb")
c.Offset(0, i + 2).Value = RegexMid(myStr, sURLdate, "br gb")
c.Offset(0, i + 3).Value = RegexMid(myStr, sURLdate, "class=gb")
Next c

*****Below is the expression referenced above

Private Function RegexMid(s As String, sDate As String, sTempType As String)
As String
Dim re As Object, mc As Object
Set re = CreateObject("vbscript.regexp")
re.IgnoreCase = True
re.MultiLine = True
re.Global = True
re.Pattern = "\b" & sDate & "/DailyHistory[\s\S]+?" & sTempType & "\D+(\d+)"

If re.test(s) = True Then
Set mc = re.Execute(s)
RegexMid = mc(0).submatches(0)
End If
Set re = Nothing
End Function
