Detailed Description

XPath query result set.

Member Function Documentation

Empty()

bool Urho3D::XPathResultSet::Empty

(

)

const

Return whether result set is empty.

FirstResult()

XMLElement Urho3D::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().

Here is the call graph for this function:

operator[]()

XMLElement Urho3D::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().

Size()

unsigned Urho3D::XPathResultSet::Size

(

)

const

Return size of result set.
