Method Detail

getXPath

public SynapseXPath getXPath()

Get the XPath expression.

Returns:

the XPath expression

setXPath

public void setXPath(SynapseXPath xpath)

Set the XPath expression.

Parameters:

xpath - the XPath expression

setXPathString

public void setXPathString(String xpathString)

Set the string representation of the XPath expression. Note that this information is not mandatory and only used for debugging purposes. Setting the string representation explicitly may be useful to make sure that debugging messages contain the XPath expression in the exact form as specified by the user.

Parameters:

xpathString - a string representation of the XPath expression

selectOMNode

public OMNode selectOMNode(MessageContext synCtx,
                           SynapseLog synLog)

Get the first node selected by the configured XPath expression. If no XPath expression is set, the first child element of the SOAP body is returned, i.e. in this case the method behaves as if the XPath expression is s11:Body/child::*[position()=1] | s12:Body/child::*[position()=1].

Parameters:

synCtx - the message context

synLog -

Returns:

the first node selected by the XPath expression

Throws:

SynapseException - if the evaluation of the XPath expression failed or didn't result in an OMNode

toString

public String toString()

Get a string representation of the XPath expression for debugging purposes.

Overrides:

toString in class Object
