[View source]
def attributes_count #

Returns attribute count of the node.


[View source]
def depth #

Returns the current nesting depth of the reader.


[View source]
def empty_element? #

Checks if the node is an empty element.


[View source]
def expand : XML::Node #

Expands the node to a XML::Node that can be searched with XPath etc. The returned XML::Node is only valid until the next call to #read.

Raises a XML::Error if the node could not be expanded.


[View source]
def expand? : XML::Node? #

Expands the node to a XML::Node that can be searched with XPath etc. The returned XML::Node is only valid until the next call to #read.

Returns nil if the node could not be expanded.


[View source]
def has_attributes? #

Checks if the node has any attributes.


[View source]
def move_to_attribute(name : String) #

Moves to the XML::Reader::Type::ATTRIBUTE with the specified name.


[View source]
def move_to_element #

Moves from the XML::Reader::Type::ATTRIBUTE to its containing XML::Reader::Type::ELEMENT.


[View source]
def move_to_first_attribute #

Moves to the first XML::Reader::Type::ATTRIBUTE of the node.


[View source]
def move_to_next_attribute #

Moves to the next XML::Reader::Type::ATTRIBUTE of the node.


[View source]
def name #

Returns the name of the node.


[View source]
def next #

Moves the reader to the next node while skipping subtrees.


[View source]
def next_sibling #

Moves the reader to the next sibling node while skipping subtrees.


[View source]
def node_type : XML::Reader::Type #

Returns the XML::Reader::Type of the node.


[View source]
def read #

Moves the reader to the next node.


[View source]
def read_inner_xml #

Returns the node's XML content including subtrees.


[View source]
def read_outer_xml #

Returns the XML for the node and its content including subtrees.


[View source]
def to_unsafe : LibXML::XMLTextReader #

Returns a reference to the underlying LibXML::XMLTextReader.


[View source]
def value #
