hxextract(1) extract selected elements from a HTML or XML file


hxextract [ -h | -? ] [ -x ] [ -s text ] [ -e text ] [ -b base ] element-or-class [ -c configfile | file-or-URL ]


hxextract outputs all elements with a certain name and/or class.

Input must be well-formed, since no HTML heuristics are applied.


The following options are supported:
Use XML format conventions.
-s text
Insert text at the start of the output.
-e text
Insert text at the end of the output.
-b base
URL base
-c configfile
Read @chapter lines from configfile (lines must be of the form "@chapter filename") and extract elements from each of those files.
-h, -?
Print command usage.


The following operands are supported:
The name of an element to extract (e.g., "H2"), or the name of a class preceded by "." (e.g., ".example") or a combination of both (e.g., "H2.example").
A file name or a URL. To read from standard input, use "-".


To use a proxy to retrieve remote files, set the environment variables http_proxy and ftp_proxy. E.g., http_proxy=http://localhost:8080/


Remote files (specified with a URL) are currently only supported for HTTP. Password-protected files or files that depend on HTTP "cookies" are not handled. (You can use tools such as curl(1) or wget(1) to retrieve such files.)
