"be consistent"

comment on

( #3333=superdoc: print w/replies, xml ) Need Help??

It seems to me that the sticking point is going to be deciding what qualifies as "pure text." Getting the content out of the XML is fairly trivial: just walk recursively through the XML file after loading it into some XML parsing module, and grab the values of the "content" keys. (I only downloaded about 0.2% of the file as a sample, but that appears to be consistent.) The simple bit of code below does that, counts the "words" in a dictionary hash, and outputs the sorted results. However, since it splits the text on whitespace, the resulting words contain a lot of punctuation, including wiki formatting. So you'll have to parse that out, and also deal with other issues: Unicode and HTML encoded characters, embedded HTML tags, "wide characters," and more.

#!/usr/bin/env perl use Modern::Perl; use XML::Simple; use Data::Dumper; my $xml = XML::Simple->new(); my $in = $xml->XMLin('wiki.xml'); my %dict; walk($in); for (sort {$a cmp $b} keys %dict){ say "$dict{$_} $_"; } sub walk { my $h = shift; for my $k (keys %$h){ if($k eq 'content'){ add_to_dict($h->{$k}); } elsif( ref($h->{$k}) eq 'HASH' ){ walk($h->{$k}); } } } sub add_to_dict { my $text = shift; for my $w (split /\s+/, $text){ $dict{$w}++; } }

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.
