Conditional Regular Expression in VBA - regex

Question

I am parsing multiple HTML files using RegEx in Excel VBA (i know not the best thing to do) but I have this case which can either be - Scenario 1:
<span class="big vc vc_2 "><strong><i class="icon icon-angle-circled-down text-danger"></i>£51,038</strong> <span class="small">(-2.12%)</span></span>
or could be - Scenario 2:
<span class="big vc vc_2 "><strong><i class="icon icon-angle-circled-up text-success"></i>£292,539</strong> <span class="small">(14.13%)</span></span>
If the class ends in danger, I want to return -51038 and -2.12%
If the class ends in success, I want to return +292539 and 14.13%
The code I have been using for the second scenario and works fine is:
Sub Test()
With CreateObject("VBScript.RegExp")
.Global = True
.MultiLine = True
.IgnoreCase = False
.Pattern = "<i class=""icon icon-angle-circled-up text-success""></i>([\s\S]*?)<"
sValue = HtmlSpecialCharsDecode(.Execute(sContent).Item(0).SubMatches(0))
End With
sValue = CleanString(sValue)
End sub
Function HtmlSpecialCharsDecode(sText)
With CreateObject("htmlfile")
.Open
With .createElement("textarea")
.innerHTML = sText
HtmlSpecialCharsDecode = .Value
End With
End With
End Function
Function CleanString(strIn As String) As String
Dim objRegex
Set objRegex = CreateObject("vbscript.regexp")
With objRegex
.Global = True
.Pattern = "[^\d]+"
CleanString = .Replace(strIn, vbNullString)
End With
End Function

All you need to do is add some more capturing groups with "or" conditions in them. In your case, you want the group (success|danger) (also (up|down) based on the examples). Then, instead of just checking the only submatch, check for the conditions that you put in your pattern:
Dim regex As Object
Dim matches As Object
Dim expr As String
expr = "<i class=""icon icon-angle-circled-(up|down) text-(success|danger)""></i>(.*?)</.*\((.*)%\)<.*"
Set regex = CreateObject("VBScript.RegExp")
With regex
.Global = True
.MultiLine = True
.IgnoreCase = False
.Pattern = expr
Set matches = .Execute(sContent)
End With
Dim isDanger As Boolean
If matches.Count > 0 Then
isDanger = (HtmlSpecialCharsDecode(matches.item(0).SubMatches(1)) = "danger")
sValue1 = HtmlSpecialCharsDecode(matches.item(0).SubMatches(2))
sValue2 = HtmlSpecialCharsDecode(matches.item(0).SubMatches(3))
End If
If isDanger Then
'Was "danger"
Debug.Print -CLng(CleanString(sValue1))
Debug.Print -CDbl(sValue2)
Else
'Was "success"
Debug.Print CLng(CleanString(sValue1))
Debug.Print CDbl(sValue2)
End If
