ok then,

$po->traverse(1, $a_node_name, $function, $somedata);

the first field after traverse is 1 (traverse this node) or 0 (don't do this, threat this link as "dead")

The second field is the node name to apply

The third is an action to do when you pass through this node, you can use here as argument several functions provided with the module.

(i.e \&_changeRefKeysCB, \&_abbrevInlineImageCB, \&_changeStringCB or \&_getRefListCB)

and fourth field is the data implied in this action (i.e $im_a_list)

Hope this helps, bye

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
