hxselect - extract elements or attributes that match a (CSS) selector
hxselect [ -i ] [ -c ] [ -l language ] [ -s separator ] selectors
hxselect reads a well-formed XML document and outputs all elements and attributes that match one of the CSS selectors that are given as an argument. For example hxselect ol li:first-child selects the first li (list item in XHTML) in an ol (ordered list). If there are multiple selectors, they must be separated by commas. For example, hxselect p + ul, blockquote ol selects all ul elements that follow a p and all ol elements that are descendants of a blockquote element. The command operates on the standard input. hxselect assumes that class selectors (".foo") refer to an attribute called "class" and that ID selectors ("#foo") refer to an attribute called "id". The experimental attribute node selector '::attr(name)' is supported and selects the attribute of that name. Comments and processing instructions are ignored, i.e., they are read but never written.
The following options are supported: -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. If an attribute rather than an element is selected (::attr() selector), only the value of the attribute is printed. -l language Sets the default language, in case the root element doesn't have an xml:lang attribute (default: none). Example: -l en -s separator A string to print after each match (default: empty). Accepts C-like escapes. Example: -s '\n\n' to print an empty line after each match.
The following operand is supported: selectors One or more comma-separated selectors. Most selectors from CSS level 3 are supported, with the exception of selectors that require interaction (e.g., ':active') or layout (e.g., ':first-line).
