in thread Confusion ,XML::SIMPLE with DATA:DUMPER

i have some questions left to understand this.
with twig_roots it will make me an array if more then 1 entry is presented ?
$reason->prev_siblings points to that array so the script process it one by one
what means prev_siblings ?

    twig_roots doesen't make an array, it makes a tree, with the document root as the root, and the elements listed in the hash as first children. Then the descendants of those elements compose the rest of the tree. prev_siblings means previous siblings. When you get a reason element, at that poit the tree is made of the root, with the phone elements as children, and the reason element as the last child. $reason->prev_siblings will then return the list of phone numbers. Once you're done printing them, you can get rid of them through the purge method, so they don't interfere with the processing of the next set of data.

    Does it make sense?

      yep thx, now i understand this twig_root and the rest
      thx ultibuzz
