org.springframework.integration.transformer.AbstractTransformer
org.springframework.integration.xml.transformer.XPathTransformer
public class XPathTransformer
Transformer implementation that evaluates an XPath expression against the inbound
Message payload and returns a Message whose payload is the result of that evaluation.
Prior to evaluation, the payload may be converted by the configured XmlPayloadConverter
instance. The default converter type is DefaultXmlPayloadConverter
.
The evaluation result type will depend on either the enumeration value provided to
setEvaluationType(XPathEvaluationType)
or the presence of a NodeMapper
,
which takes precedence. If no NodeMapper
or evaluation type is configured explicitly,
the default evaluation type is XPathEvaluationType.STRING_RESULT
.

public XPathTransformer(java.lang.String expression)
XPathTransformer
that will create an XPath expression from the given String
to be evaluated against converted inbound Message payloads.
public XPathTransformer(org.springframework.xml.xpath.XPathExpression expression)
XPathTransformer
that will evaluate the given XPathExpression
against converted inbound Message payloads.

public void setEvaluationType(XPathEvaluationType evaluationType)
XPathEvaluationType
. The default is XPathEvaluationType.STRING_RESULT
.
public void setNodeMapper(org.springframework.xml.xpath.NodeMapper<?> nodeMapper)
NodeMapper
to use for generating the result object. By default the NodeMapper is null,
but if explicitly set, type determination is the responsibility of the NodeMapper, taking precedence
over any configured evaluationType.
public void setConverter(XmlPayloadConverter converter)
XmlPayloadConverter
to use when converting a Message payload prior to XPath evaluation.
