( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Monks,

I just started with XML::Twig and I like it. But I need recursion during my parsing process. Whenever I call parse(...) or parsefile(...) inside a twig_handler everything works fine but the following line is printed out separately:

calling depth after parsing is finished at /usr/lib/perl5/vendor_perl/5.8.6/i686-linux/XML/Parser/Expat.pm line 474

Is there a way to avoid this message? Turning off -w did not do it. I see that it has got something to do with Expat but having taken a closer look to the specified .pm files did not help. Below there is a code snippet for better understanding:

#!/usr/bin/perl -w use strict; use XML::Twig; my $t = XML::Twig->new( twig_handlers => { child => \&onChild } ); $t->parse('<node id="17"><content>foo bar</content><child file="19.xml +" /></node>'); sub onChild { my ($t, $child) = @_; my $atts = $child->atts; $t->parsefile($atts->{file}); }


The file "19.xml" exists and its content does not matter. There is no further recursion in that file.
Thank you.

reading between the lines is my real pleasure

  • 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.
