Method Detail

setBuffering

public void setBuffering(boolean enable)
Allows for multiple queries against the same stream

Parameters:
enable - if set to true then multiple queries will be supported.

getNode

public <T> T getNode(String expression,
                     Class<T> cls)
Find the matching XML node and convert it into an instance of the provided class. The default JAXB MessageBodyReader is currently used in case of non-primitive types.

Parameters:
expression - XPath expression
cls - class of the node
Returns:
the instance representing the matching node

getNode

public <T> T getNode(String expression,
                     Map<String,String> namespaces,
                     Class<T> cls)
Find the matching XML node and convert it into an instance of the provided class. The default JAXB MessageBodyReader is currently used in case of non-primitive types.

Parameters:
expression - XPath expression
namespaces - the namespaces map, prefixes which are used in the XPath expression are the keys, namespace URIs are the values; note, the prefixes do not have to match the actual ones used in the XML instance.
cls - class of the node
Returns:
the instance representing the matching node

getNodes

public <T> T[] getNodes(String expression,
                        Class<T> cls)
Find the list of matching XML nodes and convert them into an array of instances of the provided class. The default JAXB MessageBodyReader is currently used in case of non-primitive types.

Parameters:
expression - XPath expression
cls - class of the node
Returns:
the array of instances representing the matching nodes

getNodes

public <T> T[] getNodes(String expression,
                        Map<String,String> namespaces,
                        Class<T> cls)
Find the list of matching XML nodes and convert them into an array of instances of the provided class. The default JAXB MessageBodyReader is currently used in case of non-primitive types.

Parameters:
expression - XPath expression
namespaces - the namespaces map, prefixes which are used in the XPath expression are the keys, namespace URIs are the values; note, the prefixes do not have to match the actual ones used in the XML instance.
cls - class of the node
Returns:
the array of instances representing the matching nodes

getLink

public URI getLink(String expression)
Find an attribute or text node representing an absolute or relative link and convert it to URI

Parameters:
expression - the XPath expression
Returns:
the link

getLink

public URI getLink(String expression,
                   Map<String,String> namespaces)
Find an attribute or text node representing an absolute or relative link and convert it to URI

Parameters:
expression - the XPath expression
namespaces - the namespaces map, prefixes which are used in the XPath expression are the keys, namespace URIs are the values; note, the prefixes do not have to match the actual ones used in the XML instance.

Find attributes or text nodes representing absolute or relative links and convert them to URIs

Parameters:
expression - the XPath expression
namespaces - the namespaces map, prefixes which are used in the XPath expression are the keys, namespace URIs are the values; note, the prefixes do not have to match the actual ones used in the XML instance.
Returns:
the links

getBaseURI

public URI getBaseURI()
Returns the value of the xml:base attribute, if any. This can be used to calculate an absolute URI provided the links in the actual XML instance are relative.

Returns:
the xml:base value

getValue

public String getValue(String expression)
Find the attribute or simple/text node

Parameters:
expression - the XPath expression

getValue

public <T> T getValue(String expression,
                      Map<String,String> namespaces,
                      Class<T> cls)
Find the attribute or simple/text node and convert the string value to the instance of the provided class, example, Integer.class.

Parameters:
expression - the XPath expression
namespaces - the namespaces map, prefixes which are used in the XPath expression are the keys, namespace URIs are the values; note, the prefixes do not have to match the actual ones used in the XML instance.
