示例1: collectMatchingRules

{
    ASSERT(matchRequest.ruleSet);
    ASSERT(m_state.element());

    const StyleResolver::State& state = m_state;
    Element* element = state.element();
    const StyledElement* styledElement = state.styledElement();
    const AtomicString& pseudoId = element->shadowPseudoId();
    if (!pseudoId.isEmpty()) {
        ASSERT(styledElement);
        collectMatchingRulesForList(matchRequest.ruleSet->shadowPseudoElementRules(pseudoId.impl()), matchRequest, ruleRange);
    }

#if ENABLE(VIDEO_TRACK)
    if (element->isWebVTTElement())
        collectMatchingRulesForList(matchRequest.ruleSet->cuePseudoRules(), matchRequest, ruleRange);
#endif
    // Check whether other types of rules are applicable in the current tree scope. Criteria for this:
    // a) it's a UA rule
    // b) the tree scope allows author rules
    // c) the rules comes from a scoped style sheet within the same tree scope
    TreeScope* treeScope = element->treeScope();
    if (!MatchingUARulesScope::isMatchingUARules()
        && !treeScope->applyAuthorStyles()
        && (!matchRequest.scope || matchRequest.scope->treeScope() != treeScope)
        && m_behaviorAtBoundary == SelectorChecker::DoesNotCrossBoundary)
        return;

    // We need to collect the rules for id, class, tag, and everything else into a buffer and
    // then sort the buffer.
    if (element->hasID())
        collectMatchingRulesForList(matchRequest.ruleSet->idRules(element->idForStyleResolution().impl()), matchRequest, ruleRange);
    if (styledElement && styledElement->hasClass()) {
        for (size_t i = 0; i < styledElement->classNames().size(); ++i)
