cssdiff(1) [debian man page]
cssdiff(1) CRM114 cssdiff(1) NAME cssdiff - generate a difference summary of two .css files SYNOPSIS cssdiff [cssfile 1] [cssfile 2] WARNING 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. DESCRIPTION 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. OPTIONS There are no options to cssdiff. SHORTCOMINGS 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". "E#myid" my $foo = $css->select('div#foo'); An "E" element with "ID" equal to "myid". E:not(s) An "E" element that does not match simple selector "s". my $others = $css->select('div p:not(:first-child)'); "E F" An "F" element descendant of an "E" element. my $headlines = $css->select('div h1'); "E > F" An "F" element child of an "E" element. my $headlines = $css->select('html > body > div > h1'); "E + F" An "F" element immediately preceded by an "E" element. my $second = $css->select('h1 + h2'); "E ~ F" An "F" element preceded by an "E" element. my $second = $css->select('h1 ~ h2'); "E, F, G" Elements of type "E", "F" and "G". my $headlines = $css->select('h1, h2, h3'); "E[foo=bar][bar=baz]" An "E" element whose attributes match all following attribute selectors. my $links = $css->select('a[foo^="b"][foo$="ar"]'); ATTRIBUTES
