Question

我有一个xml文件，如下所示。

<?xml version='1.0' encoding='UTF-8'?>
<machineDetail>
  <machineData>
    <machineNumber>00000001</machineNumber>
    <concessionUnitType>NONE</concessionUnitType>
    <machineType>SCHAERER</machineType>
    <customerNumber>69990005</customerNumber>
    <equipmentLocation>REM</equipmentLocation>
    <installedDate>2013-08-01T00:00:00.000+0000</installedDate>
  </machineData>
  <machineData>
    <machineNumber>00001024</machineNumber>
    <concessionUnitType>NONE</concessionUnitType>
    <machineType>IBS4</machineType>
    <customerNumber>69990005</customerNumber>
    <equipmentLocation>1024</equipmentLocation>
    <installedDate>2011-09-29T00:00:00.000+0000</installedDate>
  </machineData>
</machineDetail>

现在我必须将2 xmls分成像

这样的数据

1.XML

<?xml version='1.0' encoding='UTF-8'?>
    <machineDetail>
      <machineData>
        <machineNumber>00000001</machineNumber>
        <concessionUnitType>NONE</concessionUnitType>
        <machineType>SCHAERER</machineType>
        <customerNumber>69990005</customerNumber>
        <equipmentLocation>REM</equipmentLocation>
        <installedDate>2013-08-01T00:00:00.000+0000</installedDate>
      </machineData>
</machineDetail>

2.XML

<?xml version='1.0' encoding='UTF-8'?>
  <machineDetail>
    <machineData>
        <machineNumber>00001024</machineNumber>
        <concessionUnitType>NONE</concessionUnitType>
        <machineType>IBS4</machineType>
        <customerNumber>69990005</customerNumber>
        <equipmentLocation>1024</equipmentLocation>
        <installedDate>2011-09-29T00:00:00.000+0000</installedDate>
      </machineData>
    </machineDetail>

这必须在骡子中完成。在这种情况下请建议使用xslt。我是骡子的新人。

Answer 1

将分割器与xpath MEL表达式结合使用：如下所示：

system.time({  temp_env <- new.env()
               for(i in 1:length(x)){
                 y = x[i]
                 x1 = y*2
                 x2 = y*3
                 x3 = y*4
                 assign(paste0("obj", i), cbind(x1, x2, x3), envir = temp_env)
               }
               mydata_env <- do.call("rbind", 
                                     mget(paste0("obj", 1:length(x)), envir = temp_env))
             })

user  system elapsed 
0.09    0.00    0.09

这将创建两个XML文档，如下所示：

<splitter expression="#[xpath('//machineDetail/machineData')]" doc:name="Splitter"/>

然后在拆分消息时使用XSLT或类似方法将XML包装在一个 <machineData> <machineNumber>00001024</machineNumber> <concessionUnitType>NONE</concessionUnitType> <machineType>IBS4</machineType> <customerNumber>69990005</customerNumber> <equipmentLocation>1024</equipmentLocation> <installedDate>2011-09-29T00:00:00.000+0000</installedDate> </machineData>元素

Answer 2

以下流程应该按照您的要求进行。如果需要，您可能需要清理命名空间。
