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：

/*** add the new information which configured in original xml and finally generate the new xml*/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 XMLModifyInfoExtractorList<AddElement> addElementInfoList = extractor.getAddElementInfoList();List<Node> nodes ;for(AddElement addElement : addElementInfoList){

//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 XMLModifyInfoExtractorList<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 itString 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：

/*** remove the information which configured in original xml and finally generate the new xml*/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 XMLModifyInfoExtractorList<RemoveElement> removeElementInfoList = extractor.getRemoveElementInfoList();List<Node> nodes ;for(RemoveElement removeElement : removeElementInfoList){
String testcaseXPath =removeElement.getTestcaseXPath();String path =removeElement.getPath();nodes = doc.selectNodes(path);for(Node node :nodes){
//if in the node is in matching testcase ,then remove itString 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。
