HasXPath Method
Determines whether a specific element exists in the document.
Syntax
bool HasXPath(const QString& qsxpath);
Remarks
The XPath property implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML response.
The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location.
Setting the XPath property to an xpath that does not exist will cause an error. You can use the HasXPath method to determine if a particular xpath exists before setting it with XPath.
Error Handling
This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
