我们分为3个方法依次对于<add_elements>,<update_elements>,<remove_elements>进行解析：
对于<add_elements>内部遍历解析的代码如下：

/**

*/
publicstaticString addElementToXML(String xmlString ,XMLModifyInfoExtractor extractor,String originalFilePath) throwsException{
Document doc =
null
;
doc = DocumentHelper.parseText(xmlString);
extractor.extractModifyInfo(originalFilePath);
//All the add information are provided by XMLModifyInfoExtractor

List<Node> nodes ;
for

nodes = doc.selectNodes(path);
for
(Node node :nodes){
//if in the node is in matching testcase ,then remove it
String nodeUniquePath = node.getUniquePath();
if
(nodeUniquePath.indexOf(testcaseXPath) !=-
1
){
//node.getParent().remove(node);
//node.setText(value);
Element addingPointElement = (Element) node;
addingPointElement.add(newElementSnippet);
}
}
}
returndoc.asXML();
}

对于<update_elements>内部元素进行遍历的代码如下：

/**
* update the information which configured in original xml and finally generate the new xml
*/
publicstaticString updateElementFromXML(String xmlString ,XMLModifyInfoExtractor extractor,String originalFilePath) throwsException{
Document doc =
null
;
doc = DocumentHelper.parseText(xmlString);
extractor.extractModifyInfo(originalFilePath);
//All the update information are provided by XMLModifyInfoExtractor
List<UpdateElement> updateElementInfoList = extractor.getUpdateElementInfoList();
List<Node> nodes ;
for
(UpdateElement updateElement : updateElementInfoList){
String testcaseXPath =updateElement.getTestcaseXPath();
String path =updateElement.getPath();
String value=updateElement.getValue();
nodes = doc.selectNodes(path);
for
(Node node :nodes){
//if in the node is in matching testcase ,then remove it
String nodeUniquePath = node.getUniquePath();
if
(nodeUniquePath.indexOf(testcaseXPath) !=-
1
){
node.setText(value);
}
}
}
returndoc.asXML();
}

对于<remove_elements>中元素进行遍历解析的代码如下：
|
1
2

/**

*/
publicstaticString removeElementFromXML(String xmlString ,XMLModifyInfoExtractor extractor,String originalFilePath) throwsException{
Document doc =
null
;
doc = DocumentHelper.parseText(xmlString);
extractor.extractModifyInfo(originalFilePath);
//All the remove information are provided by XMLModifyInfoExtractor
List<RemoveElement> removeElementInfoList = extractor.getRemoveElementInfoList();
List<Node> nodes ;
for
(RemoveElement removeElement : removeElementInfoList){
String testcaseXPath =removeElement.getTestcaseXPath();
String path =removeElement.getPath();

for

//if in the node is in matching testcase ,then remove it
String nodeUniquePath = node.getUniquePath();
if
(nodeUniquePath.indexOf(testcaseXPath) !=-
1
){
node.getParent().remove(node);
}
}
}
returndoc.asXML();
}

最后，当执行3步骤动作系列转化之后，最终的xml文件就是包含最终的我们修改后的结果了。
