[Resolved] RegEx Help
I've never worked with Regular Expressions in VB, but am pretty good with it in PHP.
What I need to do is get rid of <font>text here</font>, no matter what "text here" is.
In VB, the expression would be something like "/<font>(.*)</font>/", but that doesn't seem to work in VB.
Also, when I distribute this application, what files will I have to include for the Reg Expression Library?

This is what I'm trying:
VB Code:
Option Explicit
Private Sub cmdConvert_Click()
Dim strHTML As String
Dim regEx As RegExp
Set regEx = New RegExp
regEx.IgnoreCase = True
regEx.Global = True
strHTML = txtHTML.Text
strHTML = Replace(strHTML, "<html>", "", , , vbTextCompare)
strHTML = Replace(strHTML, "</html>", "", , , vbTextCompare)
regEx.Pattern = "<font>(.*)</font>"
strHTML = regEx.Replace(strHTML, " this was replaced ")
rtfDisplay.Text = strHTML
Set regEx = Nothing
End Sub
And it seems to replace all instances, but it only shows " this was replaced " once, instead of for all occurances?

Anybody? 
I really just need to know how to access the wildcards. In PHP, "\\1" would access the value of the first wildcard in the replacement, but that doesn't work here.
I've searched the forums and the web, but haven't found anything.

can you use RegEx in vb6 then?  cuz i've used it in vb.net / C# / javascript , but i've never heard of it being used in vb6 and i cant seem to find a way to reference it. if you are trying to convert a html file to a text file ( minus the html ) you can use Doument.documentelement.InnerText

Yes, you can use it in VB6. No, I am not trying to do that.

To use it in VB6, you must include a reference to Microsoft VBScript Regular Expressions 5.5 (or 1.0).
Then use code similar to what I have posted above.

You are missing one small thing (?) mark.
Code:
regEx.Pattern = "<font>.*?</font>"

Thanks. I ended up just doing a series of replaces, but I'll probably try to hook up the expressions again later, if I continue the project.
