Javascript reads xml

Copy codeThe Code is as follows :/**
* Get the set object of the XML file attributes.
* @ Param xmlDoc XML Object
* @ Param name attribute name, for example, user
* @ Return returns an Array object.
* Example XML:
* <? Xml version = '1. 0' encoding = 'utf-8'?>
* <Ekuy>
* <User>
* <Name>
* <Cnname> pig </cnname>
* </Name>
* <Age> 27 </age>

* <User>
* <Name>
* <Cnname> Xiao Xia </cnname>
* </Name>
* <Age> 26 </age>
* </User>
* </Ekuy>
