bquery
bQuery is a simple tool to quickly parse html streams with a jQuery-like expression.
Examples:
get h1 element text content
wget -qO- http://en.wikipedia.org/wiki/Secure_Shell |./bquery h1
multiple results => multiple lines
wget -qO- http://en.wikipedia.org/wiki/Secure_Shell |./bquery h2
get the first result
wget -qO- http://en.wikipedia.org/wiki/Secure_Shell |./bquery h2:first
=============================================================================
By default, the inner plain text is output. If the found element is an input, the value is output. To get the html content instead of plain text, just pass --html swith.
We can extract a specific attribute instead of text:
This example extracts all page links.
wget -qO- http://en.wikipedia.org/wiki/Secure_Shell |./bquery a -a href
