rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly address
it. Please include a thorough description of the problem with code and
data examples if at all possible.

all tags are translated into property elements.
Returns : string describing the node
Args : Bio::Node::NodeI object, string
_relation_to_string
Title : _relation_to_string
Usage : internal method used by write_tree, not to be used directly
Function: internal function used by write_tree to translate Annotation::Relation objects into xml elements.

Args : Bio::Node::AnnotatableNode (or Bio::SeqI) object that contains the Annotation::Relation,
the Annotation::Relation object,
the string
read_annotation
Title : read_annotation
Usage : $treeio->read_annotation(-obj=>$node, -path=>$path, -attr=>1);
Function: read text value (or attribute value) of the annotations corresponding to the element path
Returns : list of text values of the annotations matching the path
Args : -obj => object that contains the Annotation. (Bio::Tree::AnnotatableNode or Bio::SeqI)
-path => path of the nested elements
-attr => Boolean value to indicate whether to get the attribute of the element or the text value.
(default is 0, meaning text value is returned)
Methods for parsing the XML document
processXMLNode
Title : processXMLNode
Usage : $treeio->processXMLNode
