Regular expression

[Mark Schonewille]

Hi Paolo,

This works:

      put empty into mySource
      put empty into myStart
      put empty into myEnd
      put matchText("xxxxxx src='HTTPWEB' width='3845' height='334'  
xxxxx","src='([a-zA-Z0-9 ]+)'",mySource)
      put matchChunk("xxxxxx src='HTTPWEB' width='3845' height='334'  
xxxxx","src='([a-zA-Z0-9 ]+)'",myStart,myEnd)
      put mySource & cr & myStart & comma & myEnd

Best,

Mark
