包路径：org.geotools.xsd.Node
类名称：Node
方法名：getChild

Node.getChild介绍

[英]Returns a node corresponding to a child element which has a parsed value which is an instance of clazz. This method returns the first such node it finds and no order is guarenteed, it is providedd for convenience. This method returns null if it finds no such child mathing the above criteria.
[中]返回与子元素对应的节点，该子元素的解析值是clazz的实例。这个方法返回它找到的第一个这样的节点，并且不保证顺序，它是为了方便而提供的。此方法返回null if it finds no such child mathing the above criteria.
