Name
traverse
Synopsis
$h
->traverse(sub
, [ignoretext
])
Traverses the current element and all of its
children, invoking the callback routine
sub
for each element. The callback
routine is called with a reference to the current element (the
node), a startflag, and the depth as arguments. The start flag
is 1
when entering a node and
0
when leaving (returning to
a parent element). If the ignoretext
parameter is true (the default), then the callback routine will
not be invoked for text content. If the callback routine returns
false, the method will not traverse any child elements of that
node.
