XPath query result set.
XMLElement Dry::XPathResultSet::FirstResult | ( | ) |
Return the first result in the set. Call XMLElement::GetNextResult() to get the subsequent result in the set. Note: The XPathResultSet return value must be stored in a lhs variable to ensure the underlying xpath_node_set* is still valid while performing XPathResultSet::FirstResult(), XPathResultSet::operator [], and XMLElement::NextResult().
XMLElement Dry::XPathResultSet::operator[] | ( | unsigned | index | ) | const |
Return the n-th result in the set. Call XMLElement::GetNextResult() to get the subsequent result in the set. Note: The XPathResultSet return value must be stored in a lhs variable to ensure the underlying xpath_node_set* is still valid while performing XPathResultSet::FirstResult(), XPathResultSet::operator [], and XMLElement::NextResult().
