Trying to avoid looping entirely might not be possible. I don't see anything in Win32::OLE that would help uniquely identify an object, and that would be required to avoid looping.

You could put limits on your looping (depth, time, number of objects visited, etc). Doing a breadth-first traversal (rather than a depth-first traversal) will make it easier to produce good results while adding limits.

sub depth_first { my ($n) = @_; for ($n->children()) { depth_first($_); } } sub breadth_first { my @todo = @_; while (@todo) { my $n = shift(@todo); push @todo, $n->children(); } }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • 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.
