CSS Selector

CSS-Selector With a Modified Xml Parser

  • Provide extra position info that can be used to locate invalid value/attr(optional)

Note: Use -D NO_POS will be able to disable this feature(then std.Xml will instead of csss.Xml).

  • Not based on RegExp

  • No Dependencies

  • Ease To Use.

use .querySelector/one or .querySelectorAll/all to query XML. e.g. xml.querySelectorAll("a:not([href='#'])").

use .attrPos or .nodePos to got position of attributes/nodeName/nodeValue.

supported descendant selector:

` E : supported E F : supported E > F : supported E + F : supported Note: E ~ F : supported Note:`

supported pseudo-classes/element in Selector.hx

example:

import csss.xml.Parser;
import csss.xml.Xml;
using csss.Query;

class Main {
    static function main() {
        mymacro();
    }

    macro static function mymacro() {
        var myxml = "bin/index.html";
        var file = sys.io.File.getContent(myxml);
        var body = Parser.parse(file, false).querySelector("body");

        var x = body.querySelector(".t2 span");                              // equal body.one(".t2 span")
        trace(str(x));

        var a = body.querySelectorAll(".selector-test > :nth-child(2n+1)");  // equal body.all("...")
        for (x in a) {
            trace(str(x));
        }
        var attr = body.get("class");
        if (attr != "expected") {
            var p = body.attrPos("class");                                   // got position of attr
            var pos = haxe.macro.PositionTools.make({
                min: p,
                max: p + attr.length,
                file: myxml
            });
            haxe.macro.Context.error("click this message to location where the error occurred.", pos);
        }
        return macro null;
    }

    static function str(x: Xml) {
        var s = "<" + x.nodeName;
        for (k in x.attributes()) {
            if (k.charCodeAt(0) != ":".code)
                s += ' $k="${x.get(k)}"';
        }
        return s + ">";
    }
}

Issues

  • [Insolvable] Do not suport escaped single/double quotes.

e.g: a[title="hi \"name\"."] will get a unexpected value.

  • Do not suport two consecutive + or ~. see Query TODO

Invalid: "li + li + li", "li ~ li ~ li", "li + li ~ li", "li ~ li + li"

Available: "li + li > li", "li + li li", "li li + li", "li > li > li"
