How do I find multiple email addresses in a string using Foxpro and Regex?

Hmm... it seems the function from Rgonzo1971 works well even on web pages which is probably the main goal of this question... Am I right?
LOCAL mystring, laAddr[1]
mystring = ",,"
*mystring = FILETOSTR("Contact.htm")

? ExtractEmails(mystring, @laAddr)
FOR i = 1 TO ALEN(laAddr)
  ? laAddr[i]

PROCEDURE ExtractEmails

LOCAL oRE As VBScript.RegExp, match, matches, lnCount
oRE = CreateObject("VBScript.RegExp")

oRE.Pattern = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"
oRE.Global = .T.

lnCount = 0
matches = oRE.Execute(m.lcText)
For Each Match In matches
    lnCount = m.lnCount + 1
    DIMENSION laOut[m.lnCount]
    laOut[m.lnCount] = Match.Value

RETURN m.lnCount

pls try

Sub CallMacro()
mystring = ",,"
MsgBox TestEmails(mystring)
End Sub

Function TestEmails(strText) As String
Dim oRE As Object
Set oRE = CreateObject("VBScript.RegExp")

oRE.Pattern = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"
oRE.Global = True

Set matches = oRE.Execute(strText)
For Each Match In matches
    s = s & " Position: " & Match.FirstIndex 'Position of the match
    s = s & " Word: " & Match.Value 'The actual match
    s = s & Chr(10) 'Prints a new line
    TestEmails = s
End Function

EDIT  Changed as function
FoxPro does not include RegExp natively so you'll need to use some external library. Also different RegExp implementation exists and all of them have some specific features. E-mail address pattern has also many RegExp definitions...

So your problem is not FoxPro problem but more (or less) complex task...

Do you have the e-mail pattern already? Do you have your text string sample?

Some RegExp samples are listed e.g. here:  (This web contains a link to Craig's Boyd FLL which is good. The web just runs some unspecified scripts which may cause IE to freeze...)

RegExp e-mail patterns are e.g. here:

BTW, why RegExp?  You may simplify the task: E.g. count a number of @ characters in the text and then separate the text around this characters and you have possible e-mail. Now you may validate the e-mail. etc.

Hi pcelba,

Yes, it's for web pages. Your code is what I was looking for. Rgonzo1971 code looks good, but seems like it's written in

Thank you
