示例1: simpleSelectorToPredicate
function simpleSelectorToPredicate(
selector: cssWhat.Simple, isPolymerTemplate: boolean) {
switch (selector.type) {
case 'adjacent':
case 'child':
case 'descendant':
case 'parent':
case 'sibling':
case 'pseudo':

case 'attribute':
if (isPolymerTemplate) {
return dom5.predicates.OR(
attributeSelectorToPredicate(selector),

case 'tag':
return dom5.predicates.hasTagName(selector.name);
case 'universal':
return () => true;

}示例2: test
test('bundle documents should not have tags added to them', async () => {
const {ast} = await bundle('imports/simple-import.html');
assert.isNull(dom5.query(
ast,
dom5.predicates.OR(
dom5.predicates.hasTagName('html'),

});示例3: elementSelectorToPredicate
export function elementSelectorToPredicate(
simpleSelector: string,

const parsed = cssWhat(simpleSelector);
// The output of cssWhat is two levels of arrays. The outer level are any
// selectors joined with a comma, so it matches if any of the inner selectors
// match. The inner array are simple selectors like `.foo` and `#bar` which
// must all match.
return dom5.predicates.OR(...parsed.map((simpleSelectors) => {
return dom5.predicates.AND(...simpleSelectors.map(
(selector) => simpleSelectorToPredicate(selector, isPolymerTemplate)));
}));
