Member Function Documentation

FirstResult()

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().

operator[]()

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().
