您能否添加预期输出并更正xml文件，因为它的格式不正确…@Allan添加了一个示例预期输出。不太关心输出，但如何从内部联系部门向新来者建议：如果答案解决了您的问题，请单击大复选标记接受答案(✓) 在它旁边，也可以选择向上投票（向上投票要求至少15个信誉点）。如果您发现其他答案有帮助，请向上投票。接受和向上投票有助于未来的读者。请参阅[相关帮助中心文章][1][1]：事实上，我会根据打字错误和缩进来判断你。如果你不在意这些细节，不在意让你的问题易于阅读和理解，那么我会认为你可能也不在意其他事情。感谢艾伦的回答。我已经将你的答案标记为可接受的解决方案。实际上，我最终使用了一个变量$refID和我拥有的每个部门参考资料，然后复制属性。给了我我想要的东西。@4kshay:太好了，它帮助了你！：）你也可以按箭头投票赞成答案：）谢谢
