Groovy：创建新的xml结构以及如何在构建时插入新节点

我在Groovy中遇到了一点xml解析问题。
这就是我的数据的样子：

ID      001=1234
sID     001=q8b6v
d1      001=some Text
d2      001=more Text2
tzh     001=data
dse     001=data
ID      001=567823
sID     001=l3n37v2
d1      001=some Text
d2      001=more Text2
hrg     001=data
dfe     001=data
...

我需要身份证，sID和d1

我得到的是：

What I get:
<add>
  <doc>
    <field name='ID'>00573419</field>
    <field name='sID'>20120110572</field>
    <field name='d1'>some Text</field>
    <field name='ID'>00573406</field>
    <field name='sID'>20120111110</field>
    <field name='d1'>some Text2</field>
  </doc>
</add>

我想让它尽可能简单。所以我需要一个类似“如果这里启动一个新的regExId，然后启动一个新的xml块”的语句，这样我就可以根据需要轻松地添加数据的新部分（如d2）。没有现有的xml文件。

谢谢你提供的任何信息

这就是我想到的：

import groovy.xml.MarkupBuilder

dataFile = new File( 'data.txt' )

// A closure that will add a new doc element to our xml
def addDoc = { builder, data ->
  builder.doc {
    data.each { k, v ->
      builder.field( name:k, v )
    }
  }
}


String result = new StringWriter().with { out -> // create a StringWriter
  new MarkupBuilder( out ).with { xml ->         // pass it to MarkupBuilder
    add {                                        // create our root level element
      def data = [:]
      // Then, for each line in our input file
      dataFile.eachLine { line ->
        // Get the key and value as you had it
        def (key,value) = line.split( /001=/ )*.trim()
        // Just use the keys we want
        if( key in [ 'ID', 'sID', 'd1' ] ) {
          // If we have a new ID and we have data
          if( key == 'ID' && data ) {
            // Add it to the document
            addDoc( xml, data )
            // And start again with a new map
            data = [ ID: value ]
          }
          else {
            // Otherwise, just add the key to the map
            data[ key ] = value
          }
        }
      }
      // So, we've run out of lines. If we have data, write it in
      if( data ) addDoc( xml, data )
    }
  } 
  // Convert our StringWriter to a String (this goes into the variable `result)
  out.toString()
}
// And print it out
println result

您的数据在每行末尾都有

？我现在看到了。。。不，每行末尾没有
？编辑了该部分，谢谢。现在它应该是正确的。您的数据在每行末尾都有

？我现在看到了。。。不，每行末尾没有
？编辑了该部分，谢谢。现在它应该是正确的。只是“哇”！谢谢你！我有很多东西要学：）结果是正确的。只有一个问题：“data=[ID:value]”ID来自哪里？@user1095901这是新地图条目的键（我们知道它是

ID

）。。。放上：

数据=[（键）：值]

可能会更容易理解。它基本上是将新ID放入地图中，以便下次写入文档谢谢您的快速响应。我将把我的问题标记为已解决。再次感谢。@user1095901很高兴我能帮上忙，希望我解释得足够好：-）关键部分起了作用：）ID的语法很混乱，我期待的是带有引号的“ID”。只是“哇”！谢谢你！我有很多东西要学：）结果是正确的。只有一个问题：“data=[ID:value]”ID来自哪里？@user1095901这是新地图条目的键（我们知道它是
