Class XmlUtil

java.lang.Object
  goldengate.common.xml.XmlUtil

public class XmlUtil
extends Object

XML utility that handles simple cases as:

• XPath as /x/y/z for a node and referring to root of Document
• XPath as x/y/z for a node and referring to current referenced node
• Any XPath can be a singleton (unique node referenced by the XPath) or multiple nodes (same XPath)
• Only Element as Node: no Attribute or any other type within XML
• Any other path is not supported: //x /x@y ./ ../
• Supports special SubXml tree as element (singleton or multiple)
