Package Exports

convert-cssxpath

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (convert-cssxpath) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cssxpath

Converts CSS3 selectors into XPath expression. Based on abandoned Firebug code.

Install

npm i convert-cssxpath

Examples

const cssxpath = require('convert-cssxpath');
cssxpath.convert('[attribute]')
/*
* Output: //*[@attribute]
*/

Or if you want to test different CSS selectors - you may input them in prompt using:

const cssxpath = require('convert-cssxpath');
cssxpath.ask()
/*
* Run console interface and ask you to enter CSS selector
*/

Pseudo selector :not() is fully supported. For example:

cssxpath.convert(':not([attribute])')
/*
* Output: //*[not(@attribute)]
*/

If CSS selector is wrong console will output the reason:

cssxpath.ask()
/*
*   If invalid css was entered in the console:
* 
* CSS > :not(123)
*     > Wrong pseudo selector argument.
* 
*/

You can see other supported examples in ./test/test.js

What is next

Support of those expressions will be added in next versions:

:nth-child(n)
:nth-last-child(n)
nth-of-type(n)
nth-last-of-type(n)

Other pseudo selectors (e.g. :disabled) are also not supported. Selectors with position such as :nth-child(n) are trimmed out from input CSS in this version.

Changelog

- v.0.0.4 full support of :not(selector)
