CSS::DOM::Util - Utility functions for dealing with CSS tokens VERSION
Version 0.14 SYNOPSIS
use CSS::DOM::Util ':all'; # or: use CSS::DOM::Util qw[ escape unescape escape_ident unescape_url escape_str unescape_str ]; DESCRIPTION
This module provides utility functions for dealing with CSS tokens. FUNCTIONS
All functions below that take one argument have a "($)" prototype, so they have the same precedence as "closedir" and "delete". escape $string, $chars_to_escape This escapes any characters in $string that occur in $chars_to_escape, which is interpreted as a regular expression. The regexp must consume just one character; otherwise you'll find chars missing from the output. ASCII vertical whitespace (except the vertical tab) is always escaped. Printable non-alphanumeric ASCII characters and the space character are escaped with a single backslash. Other characters are encoded in hexadecimal. "escape" also considers that you might want to include the escaped string in a larger string, so it appends a space if the escaped string ends with a hexadecimal escape with fewer than six digits. unescape $string This turns something like "H65llo" into "Hello" (including quotes). escape_ident $string escape_ident $string, $more_chars_to_escape This escapes $string as a CSS identifier, escaping also any characters matched by $more_chars_to_escape. unescape_url $url_token Returns the URL that the token represents. escape_str $string Returns a CSS string token containing $string (within quotes; characters possibly escaped). unescape_str $string_token Returns the value that a CSS string token represents.
