Extract a value from a string

Hello,

Can you advise me what is the best way to get '123456789' from the string

HTML Code:

---

<Log xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.nrf-arts.org/IXRetail/namespace/">
<Transaction SourceSystem="1">
<RetailStoreID>999</RetailStoreID>
<RevenueCenterID>0</RevenueCenterID>
<WorkstationID>123456789</WorkstationID>
<RegisterTransactionNumber>122</RegisterTransactionNumber>
</Transaction>
</Log>

Thanks

You can use either an XmlReader object or Regex.

Using .IndexOf() would be a shorter way, but regex would probably be simpler.

try this:

vb Code:

Dim testStr As String = "<WorkstationID>123456789</WorkstationID>"
Dim rx As New Regex("(?<=<WorkstationID>)\d+(?=</WorkstationID>)")
MsgBox(rx.Match(testStr).Value)

don't forget to import regex:

vb Code:

Imports System.Text.RegularExpressions
