Question

this works:

<a>apple</a>

node match {
  case <a>{contents}</a> => "It's an a: "+ contents
  case _ => "It's something else."
}

---

how can i modifiy this example, so that it only matches a node with a tag “a” and attribute id=2:
something as follows:

<a id="2">apple</a>

node match {
  case <a id="2">{contents}</a> => "It's an a: "+ contents
  case _ => "It's something else."
}

but this does not compile.

Here is one way to do it:

node match {
  case a @ <a>{contents}</a> if (a \ "@id").text == "2" => "It's an a: " + contents
  case _ => "It's something else."
}
