xselect.c

HTML-XML-utils由一套小型C程序（过滤器）组成

/*
 * select -- extract elements matching a selector
 *
 * Assumes that class selectors (".foo") refer to an attribute called
 * "class".
 *
 * Assumes that ID selectors ("#foo") refer to an attribute called
 * "id".
 *
 * Options:
 *
 * -l language
 *
 *     Sets the default language, in case the root element doesn't
 *     have an xml: lang attribute. Example: -l en. Default: none.
 *
 * -s separator
 *
 *     A string to print after each match. Accepts C-like escapes.
 *     Example: -s '\n\n' to print an empty line after each match.
 *     Default: empty string.
 *
 * -i
 *
 *     Match case-insensitively. Useful for HTML and some other
 *     SGML-based languages.
 *
 * -c
 *
 *     Print content only. Without -c, the start and end tag of the
 *     matched element are printed as well; with -c only the contents
 *     of the matched element are printed.
