Public Member Functions | |
| XPathQuery () | |
| Construct empty. | |
| XPathQuery (const String &queryString, const String &variableString=String::EMPTY) | |
| Construct XPath query object with query string and variable string. The variable string format is "name1:type1,name2:type2,..." where type is one of "Bool", "Float", "String", "ResultSet". | |
| ~XPathQuery () | |
| Destruct. | |
| void | Bind () |
| Bind query object with variable set. | |
| bool | SetVariable (const String &name, bool value) |
| Add/Set a bool variable. Return true if successful. | |
| bool | SetVariable (const String &name, float value) |
| Add/Set a float variable. Return true if successful. | |
| bool | SetVariable (const String &name, const String &value) |
| Add/Set a string variable. Return true if successful. | |
| bool | SetVariable (const char *name, const char *value) |
| Add/Set a string variable. Return true if successful. | |
| bool | SetVariable (const String &name, const XPathResultSet &value) |
| Add/Set an XPath query result set variable. Return true if successful. | |
| bool | SetQuery (const String &queryString, const String &variableString=String::EMPTY, bool bind=true) |
| Set XPath query string and variable string. The variable string format is "name1:type1,name2:type2,..." where type is one of "Bool", "Float", "String", "ResultSet". | |
| void | Clear () |
| Clear by removing all variables and XPath query object. | |
| bool | EvaluateToBool (const XMLElement &element) const |
| Evaluate XPath query and expecting a boolean return value. | |
| float | EvaluateToFloat (const XMLElement &element) const |
| Evaluate XPath query and expecting a float return value. | |
| String | EvaluateToString (const XMLElement &element) const |
| Evaluate XPath query and expecting a string return value. | |
| XPathResultSet | Evaluate (const XMLElement &element) const |
| Evaluate XPath query and expecting an XPath query result set as return value. 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(). | |
| String | GetQuery () const |
| Return query string. | |
| pugi::xpath_query * | GetXPathQuery () const |
| Return pugixml xpath_query. | |
| pugi::xpath_variable_set * | GetXPathVariableSet () const |
| Return pugixml xpath_variable_set. | |
