Function Documentation

◆ XalanCreateXPath()

XalanCreateXPath ( XalanXPathEvaluatorHandle  theXalanHandle,
const char *  theXPathExpression,
const char *  theXPathExpressionEncoding,
XalanXPathHandle theXPathHandle 
)

Creates a compiled XPath instance.

Parameters
theXalanHandleThe handle of XalanXPathEvaluatorHandle instance.
theXPathExpressionThe expression to compile
theXPathExpressionEncodingThe encoding of the expression. If NULL or an empty string, the local code page is assumed.
theXPathHandleA pointer to the handle for the new instance
Returns
0 for success, or a non-zero error code upon failure

◆ XalanCreateXPathEvaluator()

XalanCreateXPathEvaluator ( XalanXPathEvaluatorHandle theHandle)

Create a XalanXPathEvaluator instance.

Parameters
theXalanHandleA pointer to the handle for the new instance.
Returns
0 for success, or a non-zero error code upon failure

◆ XalanDestroyXPath()

XalanDestroyXPath ( XalanXPathEvaluatorHandle  theXalanHandle,
XalanXPathHandle  theXPathHandle 
)

Destroys a compiled XPath instance.

Parameters
theXalanHandleThe handle of XalanXPathEvaluatorHandle instance.
theXPathHandleThe handle of XPath instance
Returns
0 for success, or a non-zero error code upon failure

◆ XalanDestroyXPathEvaluator()

XalanDestroyXPathEvaluator ( XalanXPathEvaluatorHandle  theXalanHandle)

Destroy a XalanXPathEvaluator instance.

Parameters
theXalanHandleThe handle of the instance to destroy.
Returns
0 for success, or a non-zero error code upon failure

◆ XalanEvaluateXPathAsBoolean()

XalanEvaluateXPathAsBoolean ( XalanXPathEvaluatorHandle  theXalanHandle,
XalanXPathHandle  theXPathHandle,
const char *  theXML,
int *  theResult 
)

Evaluates a compiled XPath instance.

Parameters
theXalanHandleThe handle of XalanXPathEvaluatorHandle instance.
theXPathHandleThe pointer to handle for instance
theXMLThe XML document to use for evaluating the XPath expression
theResultA pointer to an int to receive the result.
Returns
0 for success, or a non-zero error code upon failure

◆ XalanEvaluateXPathExpressionAsBoolean()

XalanEvaluateXPathExpressionAsBoolean ( XalanXPathEvaluatorHandle  theXalanHandle,
const char *  theXPathExpression,
const char *  theXPathExpressionEncoding,
const char *  theXML,
int *  theResult 
)

Evaluates an XPath expression.

Parameters
theXalanHandleThe handle of XalanXPathEvaluatorHandle instance.
theXPathExpressionThe expression to evaluate
theXPathExpressionEncodingThe encoding of the expression. If NULL or an empty string, the local code page is assumed.
theXMLThe XML document to use for evaluating the XPath expression
theResultA pointer to an int to receive the result.
Returns
0 for success, or a non-zero error code upon failure

◆ XalanXPathAPIInitialize()

XalanXPathAPIInitialize ( )

Initialize Xerces and the XPath API.

Should be called only once per process before making any other API calls.

Returns
0 for success, or a non-zero error code upon failure

◆ XalanXPathAPITerminate()

XalanXPathAPITerminate ( )

Terminate Xerces and the XPath API.

Should be called only once per process after deleting all instances of XalanXPathEvaluator. Once a process has called this function, it cannot use the API for the remaining lifetime of the process.

Returns
0 for success, or a non-zero error code upon failure
