VB.NET: Extract Xml attribute related to symbol

Say i have these Xml tag...

Code:

---

<book title=”Harry Porter  page="1_9”>
    <new id=”100”>China News</new>
    <new id=”101”>Street paper</new>
    <new id=”0”>none</it>
    …….
    <new>….</new>
  </book>

---

how do i exactly extract the 1 and 10 separately from "1_9"

Now i am using substring to extract 1 and 9, it works well...

But if the 9 becomes 10 (double digits), it will have exception if i have to loop the Xml and send the maxpage to the server...

Code:

---

page = xdoc.SelectSingleNode("//book/@page").Value.Substring(0, 1)
maxPage = xdoc.SelectSingleNode("//book/@page").Value.Substring(2, 1)

---

Thanks

Use the underscore to parse the string into the 2 components, i.e.

VB Code:

Dim value as String = xdoc.SelectSingleNode("//book/@page").Value
      Dim page As String = value.Substring(0, value.IndexOf("_"))
      Dim maxPage As String = value.Substring(value.IndexOf("_") + 1)
