XML可扩展标记语言，被设计用来传输和存储数据，其形式多样。
某些在XML中被设计出来的特性，比如XMLschemas(遵循XMLSchemas规范)和documentstypedefinitions(DTDs)都是安全问题来源。
纵然被公开的讨论了上十年，还是有一大批一大批的软件死在针对XML的攻击上。
XML可扩展标记语言，被设计用来传输和存储数据。
其形式多样例如：1.文档格式(OOXML，ODF,PDF,RSS,DOCX...)2.图片格式(SVG,EXIFHeaders,...)3.配置文件(自定义名字，一般是.xml)4.网络协议(WebDAV,CalDAV，XMLRPC,SOAP,RES

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
