HasXPath Method

Determines whether a specific element exists in the document.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
int HasXPath(const char* lpszxpath);

Unicode (Windows)
INT HasXPath(LPCWSTR lpszxpath);

- (BOOL)hasXPath:(NSString*)xpath;

#define MID_QBOBJECT_HASXPATH 11

INQB_EXTERNAL int INQB_CALL InQB_QBObject_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

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 (C++)

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.
