How to convert list of scala Xml elements to single scala Elements?

Question

So I have

val list:List[Any];
def toElement(a:Any):scala.xml.Elem;

And I want to write somthing like

val result = <span> {list.map(toElement).toElem} <span>

Answer 1

If I've understood you correctly, I think what you're after may be something like this:

// List of different types
val list: List[Any] = List("one", 2, "three", 4:Long)

// Conversion function for type 'Any' - (note .toElem or .toXml isn't a
// member of 'Any' - so that's why we need to create this)
def toElement(a: Any): scala.xml.Elem = <hello>{ a.toString }</hello>

// Usage example
val result = <span>{ list.map( toElement(_) ) }</span>    

But I guess it really depends on what type of objects you're expecting in the list, and what sort of XML elements you want them to end up looking like.

Just an idea...

val list:List[Any] = List(1, 2, "test", 3.5)

def toElement(a:Any):scala.xml.Elem = {
  scala.xml.Elem(null, a.toString, scala.xml.Null, scala.xml.TopScope)
}

val result = <span> { list map toElement } </span>

results in

<span> <1></1><2></2><test></test><3.5></3.5> </span>
