FEEDBACK¶
Mailing Lists¶
User feedback is an integral part of the evolution of this and other Bioperl
modules. Send your comments and suggestions preferably to the Bioperl mailing
list. Your participation is much appreciated.

Support¶
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
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.

-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¶
