A simple program to CRUD node and node values of xml file

I am not looking for an exact attribute or and exact node text. Example

<Items>
  <book>
    <title> Beginning Java </title>
  </book>
   <book>
    <title> Beginning ASP </title>
  </book>
  <book>
    <title> Beginning Java </title>
  </book>
  <book>
    <title> Advance Java </title>
  </book>
  <book>
    <title> Advance ASP </title>
  </book>
</items>

What I want to be able too is find all books that has “Beginning” in the title or “Advance” in the title. Sort of wild type search. What do I need, XPATH? Either ASP.NET or PHP code will help.

I am doing this to write a utility to remove broken links in iTunes music library on MAC.

Thank you

Edit: Help needed with the actual XML
I am searching based on the in front of “Location” key. Never came across such an XML which has and .

Thanks again

In terms of XPath (1.0) which ASP.NET and PHP support with the normal installations you can use /Items/book[contains(title, 'Beginning') or contains(title, 'Advance')]. Note that XML node names and therefore XPath expressions are case-sensitive, your sample is not well-formed XML as it has a start tag <Items> but an end tag </items>.

As for code to remove nodes with ASP.NET, try along the following lines:

XmlDocument doc = new XmlDocument();
doc.Load("input.xml");
XmlNodeList booksToRemove = doc.SelectNodes("/Items/book[contains(title, 'Beginning') or contains(title, 'Advance')]");
for (int i = booksToRemove.Length - 1; i >= 0; i--) {
  booksToRemove[i].ParentNode.RemoveChild(booksToRemove[i]);
}
doc.Save("output.xml");
