示例1: source
Item::Iterator::Ptr AxisStep::evaluateSequence(const DynamicContext::Ptr &context) const
{
/* If we don't have a focus, it's either a bug or our parent isn't a Path
* that have advanced the focus iterator. Hence, attempt to advance the focus on our own. */
if(!context->contextItem())
context->focusIterator()->next();
Q_ASSERT(context->contextItem());
const QXmlNodeModelIndex::Iterator::Ptr source(context->contextItem().asNode().iterate(m_axis));
return makeItemMappingIterator<Item>(ConstPtr(this), source, context);
}示例2: evaluateSingleton
Item AxisStep::evaluateSingleton(const DynamicContext::Ptr &context) const
{
/* If we don't have a focus, it's either a bug or our parent isn't a Path
* that have advanced the focus iterator. Hence, attempt to advance the focus on our own. */

context->focusIterator()->next();
Q_ASSERT(context->contextItem());
const QXmlNodeModelIndex::Iterator::Ptr it(context->contextItem().asNode().iterate(m_axis));

while(!next.isNull())
{
const Item candidate(mapToItem(next, context));
