Xml Rapidminer数据转置相当于R中的melt
我有一个Rapidminer进程，它从web API读取，使用读取XML处理响应，使用XPATH捕获XML中的一个元素。元素可以是任意数量的，结果属性是元素/text（）的串联字符串 作为连接字符串的结果，我必须将字符串拆分为多个列，如下所示：Xml Rapidminer数据转置相当于R中的melt,xml,xpath,transpose,rapidminer,Xml,Xpath,Transpose,Rapidminer,我有一个Rapidminer进程，它从web API读取，使用读取XML处理响应，使用XPATH捕获XML中的一个元素。元素可以是任意数量的，结果属性是元素/text（）的串联字符串 作为连接字符串的结果，我必须将字符串拆分为多个列，如下所示： ID Col1 Col2 Col3 Col4 Col5 Col6 A 1 5 7 8 B 2 C 4 D 3 9 10 11 12 13 我的最终目标是将其转换为以下格式： ID Ne

1.是否可以将Read XML运算符配置为将数据读入多行而不是长串接字符串？
2.如果对1的回答为否定，是否有任何操作符可以执行上述“转置”任务（类似于R中的melt函数）该

希望您可以将其用作起点。您可以在rapid miner中使用反枢轴操作符。只需查看它的文档
