    • getChildElementsByTagName

      public static List<Element> getChildElementsByTagName(Element ele, String... childEleNames)
      Retrieves all child elements of the given DOM element that match any of the given element names. Only looks at the direct child level of the given element; do not go into further depth (in contrast to the DOM API's getElementsByTagName method).
      参数:
      ele - the DOM element to analyze
      childEleNames - the child element names to look for
      返回:
      a List of child org.w3c.dom.Element instances

      @Nullable public static String getChildElementValueByTagName(Element ele, String childEleName)
      Utility method that returns the first child element value identified by its name.
      参数:
      ele - the DOM element to analyze
      childEleName - the child element name to look for
      返回:
      the extracted text value, or null if no child element found
