Regex with hyperlinks ActiveDocument.Range and Format - regex

Question

I have seen several other StackOverflow posts such as this one:
How to Use/Enable (RegExp object) Regular Expression using VBA (MACRO) in word
on using regular expressions in Microsoft Word with VBA using the Microsoft VB script Regular Expressions 5.5 Reference.
That helped me prepare the following, which I use in Word to highlight US Dollar amounts:
Sub dollarHighlighter()
Set regExp = New regExp
Dim objMatch As Match
Dim colMatches As MatchCollection
Dim offsetStart As Long
offsetStart = Selection.Start
regExp.Pattern = "\$([\,\d{1,3}]*(?:\.\d{2})?)"
regExp.Global = True
Set colMatches = regExp.Execute(Selection.Text) ' Execute search.
For Each objMatch In colMatches ' Iterate Matches collection.
Set myRange = ActiveDocument.Range(objMatch.FirstIndex + offsetStart,
End:=offsetStart + objMatch.FirstIndex + objMatch.Length)
myRange.FormattedText.HighlightColorIndex = wdYellow
Next
End Sub
While this works as expected on a list of dollar amounts within text (for the most part - among its imperfections the regex is intentionally a bit loose) it does not work as anticipated when there are hyperlinks present in the Word document.
In that instance, there appears to be a shift in offset of the highlighted characters in a somewhat unpredictable manner. I assume this is because there is a lot of new xml/css in the document.xml source file.
Ultimately, my overarching questions is, can I use regex to highlight word document contents even if it contains hyperlinks? Is it an offset question or should I run the regex on the compressed xml, re compress and reopen for better results? As when I test various regex variations on the source code, I get the anticipated results, but not when formatting what would be the Word range.
I have also asked this here: https://social.msdn.microsoft.com/Forums/en-US/3a95c5e4-9e0c-4da9-970f-e0bf801c3170/macro-for-a-regexp-search-replace?forum=isvvba&prof=required but realize it was an ancient post...
Per question below, here are some possibly helpful links:

Temporary Workaround: As suggested below Word's Wildcard find is fast if you do not stack the loops. try this:
Sub Macro2()
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
Selection.Find.Replacement.highlight = True
With Selection.Find
.Text = "$[0-9,]{1,}"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = True
.MatchCase = False
.MatchWholeWord = False
.MatchAllWordForms = False
.MatchSoundsLike = False
.MatchWildcards = True
End With
Selection.Find.Execute Replace:=wdReplaceAll
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
Selection.Find.Replacement.highlight = True
With Selection.Find
.Text = "$[0-9,]{1,}.[0-9]{2,3}"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = True
.MatchCase = False
.MatchWholeWord = False
.MatchAllWordForms = False
.MatchSoundsLike = False
.MatchWildcards = True
End With
Selection.Find.Execute Replace:=wdReplaceAll
End Sub
which basically gets all the dollar amounts highlighted. That said, complex expressions like matching a variety of date formats could get messy, but i suppose it is all possible doing them one step at a time.

Answer 1

I had not touched VBA for years but I guess it's like bicycling.
Anyways, here is a sub that should help you out. It's based on Cindy Meister sound recommendation and fills the gap between Regex and Wildcard Find using a collection of match patterns for optional parts.
First, the Wildcard matches: $[0-9,]{1,} and $[0-9,]{1,}.[0-9]{2}
It's not that different after all, isn't it? However, to take the optional fraction part into account I have to use two patterns.
And here's the routine:
Sub WildcardsHighlightWords()
Dim Word As Range
Dim WildcardCollection(2) As String
Dim Words As Variant
WildcardCollection(0) = "$[0-9,]{1,}"
WildcardCollection(1) = "$[0-9,]{1,}.[0-9]{2}"
Options.DefaultHighlightColorIndex = wdYellow
'Clear existing formatting and settings in Find
Selection.Find.ClearFormatting
Selection.Find.Replacement.ClearFormatting
'Set highlight to replace setting.
Selection.Find.Replacement.Highlight = True
'Cycle through document and find wildcards patterns, highlight words when found
For Each Word In ActiveDocument.Words
For Each WildcardsPattern In WildcardCollection
With Selection.Find
.Text = WildcardsPattern
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = True
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = True
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
Next
Next
End Sub
It should be easy to extend or modify this approach if needed.
This highlithts the Dollar amounts as desired on my end:
Note: The separator in the quantifier {n,m} is not the same in all localizations, e.g. it's {n;m} in the German version.
