Sample Programs

The example programs included with the HTML Parser distribution are listed below, with some details.

Note: On unix systems if you used the Java jar command or some older unzip utility to extract the distribution zip file, the executable flag will not have been preserved on the files in the bin directory. You can fix this by issuing the following command: 
    chmod u+x bin/*

Parser

 Parse a web page and print the tags in a simple loop.

org.htmlparser.Parser.main(String[] args) 
    bin/parser http://website_url [tag_name]
    where tag_name is an optional tag name to be used as a filter, i.e.
        A - Show only the link tags extracted from the document
        IMG - Show only the image tags extracted from the document
        TITLE - Extract the title from the document
    NOTE: this is also the default program for the htmlparser.jar, so the above could be:
    java -jar lib/htmlparser.jar http://website_url [tag_name]
