Malformed attribute selector

I’m trying the following and getting an error:

var htmlFiles = [];
$("resource[href*='.htm'][d2l_2p0:material_type='content']").each(function () {
	htmlFiles.push($(this).attr("href"));
});
return htmlFiles;

\path\to\node_modules\css-what\index.js:152
                                        throw new SyntaxError("Malformed attribute selector: " + selector);
                                        ^

I’m fairly certain that I’ve used this exact selector before with no problem. I’m guessing the problem is the colon (:) in the selector which is fairly common in XML.

Please note that I instantiated the cheerio object with the following options:

var cheerioOptions = {
	normalizeWhitespace: true,
	xmlMode: true,
	decodeEntities: false
};

It should be noted that I can access the value of the attribute via the attr method so the following does work (-around):

var htmlFiles = [];
$("resource[href*='.htm']").each(function () {
	if($(this).attr("d2l_2p0:material_type") === "content") {
		htmlFiles.push($(this).attr("href"));
	}
});
return htmlFiles;

Would you accept a PR to make a small note of this in the README? Maybe a sentence at the end of this section? https://github.com/cheeriojs/cheerio#-selector-context-root-
