pquery======grep for HTML; CLI for pyquery## Demo```$curl -s https://github.com/hupili/pquery | pquery '.content a' -p text.gitignoreLICENSEMANIFEST.inREADME.mdpquerysetup.py````pquery` is intended to integrate into your UNIX pipeline.## Install`pip install pquery`## Syntax```Usage: pquery <selector> pquery <selector> -p <projector> pquery <selector> -f <format_string> pquery -h | --helpOptions: -p: project the dict onto field `<projector>`. -f: equivalent of `<format_string>.format(item)`, where item is the dict form of one selected HTML element. -h | -v: shows this doc.Dict keys: 'tag': The HTML tag 'html': Inner HTML of the element 'text': Inner text of the element ...: [optional] Other attributes: e.g. 'href'```## Why`grep` is powerful for **lines**.HTML is structured and not line processor friendly.CSS selector is a natural grep for HTML.This script simply wraps [pyquery](http://pyquery.readthedocs.org/en/latest/) to provide a CLI.## Example 1A [course webpage](https://class.coursera.org/crypto-008/wiki/LectureSlidesPublicCourse)lists slides in `pdf` and `pptx`.Want to download all the PDFs.This saves you some click.```wget --load-cookies=cookies.txt -O- 'https://class.coursera.org/crypto-008/wiki/LectureSlidesPublicCourse' | pquery a -p href | grep pdf | xargs -P 5 -I{} wget {}```It's tedious to directly grep the PDF links out from HTML.
