IBM Host On Demand Macro <condition>元素语法错误排查求助

错误原因分析 #

你遇到的Element type "condition" must be followed by either attribute specifications, ">" or "/>"错误，核心是<condition>元素的XML语法完全不符合规范：

• 直接将条件表达式$Label_Request$!=$Label_Count$写在标签名后，没有用属性包裹，XML要求元素必须以属性声明、>或/>结尾。
• 同时使用了自闭合的<condition ... />和单独的</condition>结束标签，属于XML语法冲突，自闭合标签不需要额外的结束标签。

修正后的代码 #

IBM Host On Demand Macro的<condition>元素需要通过value属性指定条件表达式，以下是修正后的完整代码，同时调整了循环逻辑，让流程能正确根据计数判断继续循环或结束：

关键修正点 #

1. <condition>语法修正：将条件表达式放在value属性中，使用<condition value="表达式" />的正确XML格式，删除多余的</condition>结束标签。
2. 循环逻辑优化：新增Screen4作为专门的结束屏幕，Screen3通过nextscreen的condition属性判断跳转方向，避免原逻辑中屏幕同时承担判断和结束的冲突。
3. 流程控制简化：直接在nextscreen元素中使用condition属性控制跳转，这是IBM Host On Demand Macro中实现分支逻辑的标准方式。
