包路径：com.netflix.imfutility.xml.XmlParser
类名称：XmlParser

XmlParser介绍

[英]A base .xml parser.

• Maps XML to a Java model
• Performs XSD validation and throws XmlParsingException if the xml is not a valid XML according to XSD.
  [中]基地。xml解析器。
  *将XML映射到Java模型
  *根据XSD，如果xml不是有效的xml，则执行XSD验证并抛出XmlParsingException。
