      cssdiff - generate a difference summary of two .css files

      cssdiff [cssfile 1] [cssfile 2]

      This  man  page  is  taken from an older CRM114 version.  It is provided as a convenience to Debian users and may not be up-to-date.  If you
      would like to update it, please send appropriate patches to the Debian bug tracking system.

      cssdiff is a special-purpose utility to measure the distance between the classes represented by cssfile1 and cssfile2.  The  summary  result
      output  tells  how  many  features  were in each of the .css files, how many features appeared in both (balanced overlap), how many features
      appeared only in one (or unbalanced overlaps), and how often the feature set of one .css file strictly dominated the feature set of  another
      .css  file.  This set of metrics provides an intuitive way to determine the similarity (or dissimilarity) of two classes represented as .css
      files.  When using the CRM114 spamfilter, it can be used to find out how easy it will be for CRM114 to differentiate spam from nonspam  with
      your .css files.  cssdiff prints a report like e.g.

         Sparse spectra file spam.css has 1048577 bins total
         Sparse spectra file nonspam.css has 1048577 bins total

         File 1 total features            :      1605968
         File 2 total features            :      1045152

         Similarities between files       :       142039
         Differences between files        :      1279964

         File 1 dominates file 2          :      1463929
         File 2 dominates file 1          :       903113

      Note that in this case there's a big difference between the two files; in this case there are about 10 times as many differences between the
      two files as there are similarities.

      There are no options to cssdiff.

      Note that cssdiff as of version 20040816 is NOT capable of dealing with the CRM114 Winnow classifier's  floating-point  .cow  files.  Worse,
      cssdiff  is  unaware of it's shortcomings, and will try anyway. The only recourse is to be aware of this issue and not use cssdiff on Winnow
      classifier floating point .cow format files.

Mojo::DOM::CSS - CSS3 selector engine SYNOPSIS
use Mojo::DOM::CSS; # Select elements from DOM tree my $css = Mojo::DOM::CSS->new(tree => $tree); my $elements = $css->select('h1, h2, h3'); DESCRIPTION
Mojo::DOM::CSS is the CSS3 selector engine used by Mojo::DOM. SELECTORS
All CSS3 selectors that make sense for a standalone parser are supported. "*" Any element. my $all = $css->select('*'); "E" An element of type "E". my $title = $css->select('title'); "E[foo]" An "E" element with a "foo" attribute. my $links = $css->select('a[href]'); "E[foo="bar"]" An "E" element whose "foo" attribute value is exactly equal to "bar". my $fields = $css->select('input[name="foo"]'); "E[foo~="bar"]" An "E" element whose "foo" attribute value is a list of whitespace-separated values, one of which is exactly equal to "bar". my $fields = $css->select('input[name~="foo"]'); "E[foo^="bar"]" An "E" element whose "foo" attribute value begins exactly with the string "bar". my $fields = $css->select('input[name^="f"]'); "E[foo$="bar"]" An "E" element whose "foo" attribute value ends exactly with the string "bar". my $fields = $css->select('input[name$="o"]'); "E[foo*="bar"]" An "E" element whose "foo" attribute value contains the substring "bar". my $fields = $css->select('input[name*="fo"]'); "E:root" An "E" element, root of the document. my $root = $css->select(':root'); "E:checked" A user interface element "E" which is checked (for instance a radio-button or checkbox). my $input = $css->select(':checked'); "E:empty" An "E" element that has no children (including text nodes). my $empty = $css->select(':empty'); "E:nth-child(n)" An "E" element, the "n-th" child of its parent. my $third = $css->select('div:nth-child(3)'); my $odd = $css->select('div:nth-child(odd)'); my $even = $css->select('div:nth-child(even)'); my $top3 = $css->select('div:nth-child(-n+3)'); "E:nth-last-child(n)" An "E" element, the "n-th" child of its parent, counting from the last one. my $third = $css->select('div:nth-last-child(3)'); my $odd = $css->select('div:nth-last-child(odd)'); my $even = $css->select('div:nth-last-child(even)'); my $bottom3 = $css->select('div:nth-last-child(-n+3)'); "E:nth-of-type(n)" An "E" element, the "n-th" sibling of its type. my $third = $css->select('div:nth-of-type(3)'); my $odd = $css->select('div:nth-of-type(odd)'); my $even = $css->select('div:nth-of-type(even)'); my $top3 = $css->select('div:nth-of-type(-n+3)'); "E:nth-last-of-type(n)" An "E" element, the "n-th" sibling of its type, counting from the last one. my $third = $css->select('div:nth-last-of-type(3)'); my $odd = $css->select('div:nth-last-of-type(odd)'); my $even = $css->select('div:nth-last-of-type(even)'); my $bottom3 = $css->select('div:nth-last-of-type(-n+3)'); "E:first-child" An "E" element, first child of its parent. my $first = $css->select('div p:first-child'); "E:last-child" An "E" element, last child of its parent. my $last = $css->select('div p:last-child'); "E:first-of-type" An "E" element, first sibling of its type. my $first = $css->select('div p:first-of-type'); "E:last-of-type" An "E" element, last sibling of its type. my $last = $css->select('div p:last-of-type'); "E:only-child" An "E" element, only child of its parent. my $lonely = $css->select('div p:only-child'); "E:only-of-type" An "E" element, only sibling of its type. my $lonely = $css->select('div p:only-of-type'); "E.warning" my $warning = $css->select('div.warning'); An "E" element whose class is "warning".
