→fn:tokenize
===fn:tokenize===
If no separator is specifiedas second argument, a string will be tokenized at whitespace boundaries:
<pre class="brush:xquery">
fn:tokenize(" a b c d") (: yields "a", "b", "c", "d" :)
</pre>
===fn:trace===
The second argument can now be omitted:
<pre class="brush:xquery">
fn:trace(<xml/>, "Node: ")/node() (: yields the debugging output "Node: <xml/>" :),
fn:trace(<xml/>)/node() (: returns the debugging output "<xml/>" :)
</pre>
