在Groovy MarkupBuilder中使用命名空间 [英] Use of Namespaces in Groovy MarkupBuilder

问题描述

 <？xml version =1.0encoding =UTF-8 ？> 
< structure：structuralDataRoot xmlns：register =http://www.test.ch/register/1xmlns：structure =http://test.ch/structure/1> 
< structure：tester> ZH< / structure：tester> 
< structure：surveyYear> 2001< / structure：surveyYear> 
< structure：surfaceData> 
< structure：houseSurfaceData> 
< structure：creationDate> 2001-01-01< / structure：creationDate> 
< structure：localFarmId> 
< register：houseIdCategory>标记< / register：houseIdCategory> 
< register：houseId>令牌< / register：houseId> 
< / structure：localFarmId> 
< / structure：houseSurfaceData> 
< / structure> 
  

我可以将命名空间添加到xml中，如下所示：

  xml.records（'xmlns：structure'：http://test.ch/structure/1... 
  

但是我如何为xml元素创建一个名称空间前缀？
我找到的唯一解决方案是：

  tester（'xmlns：structure'：http://test.ch/structure/1，'ZH'）
  

但是，这给了我以下输出：



 < tester xmlns：structure ='http：//test.ch/structure/1'> ZH< / tester> 
  

它在语法上是正确的，但是当你有很多节点时不好阅读。


解决方案

你可以做到这一点（不知道它是你想要的）虽然你想要什么，但
$ b $ pre $ import groovy.xml.StreamingMarkupBuilder
import groovy .xml.XmlUtil
$ b $ def xmlBuilder = new StreamingMarkupBuilder（）
writer = xmlBuilder.bind {
mkp.decla reNamespace（register：http://www.test.ch/register/1）
mkp.declareNamespace（结构：http://test.ch/structure/1）
'结构：structureDataRoot'{
'structure'tester'（'ZH'）
'structure：surveyYear'（2001）
'structure：surfaceData'{
'structure：houseSurfaceData'{
'structure：creationDate'（'2001-01-01'）
'结构：localFarmId'{
'register：houseIdCategory'（'token'）
'register：houseId '（'token'）
}
}
}
}
}

println XmlUtil.serialize（writer）


这段代码输出：



 <？xml version =1.0encoding =UTF-8？> 
< structure：structuralDataRoot xmlns：register =http://www.test.ch/register/1xmlns：structure =http://test.ch/structure/1> 
< structure：tester> ZH< / structure：tester> 
< structure：surveyYear> 2001< / structure：surveyYear> 
< structure：surfaceData> 
< structure：houseSurfaceData> 
< structure：creationDate> 2001-01-01< / structure：creationDate> 
< structure：localFarmId> 
< register：houseIdCategory>标记< / register：houseIdCategory> 
< register：houseId>令牌< / register：houseId> 
< / structure：localFarmId> 
< / structure：houseSurfaceData> 
< / structure：surfaceData> 
< / structure：structuralDataRoot> 
  




I want have the following output:

<?xml version="1.0" encoding="UTF-8"?>
<structure:structuralDataRoot xmlns:register="http://www.test.ch/register/1" xmlns:structure="http://test.ch/structure/1" >
  <structure:tester>ZH</structure:tester>
  <structure:surveyYear>2001</structure:surveyYear>
  <structure:surfaceData>
    <structure:houseSurfaceData>
      <structure:creationDate>2001-01-01</structure:creationDate>
      <structure:localFarmId>
        <register:houseIdCategory>token</register:houseIdCategory>
        <register:houseId>token</register:houseId>
      </structure:localFarmId>
    </structure:houseSurfaceData>
  </structure>

I can add namespace to an xml like this:

xml.records('xmlns:structure' :"http://test.ch/structure/1" ...

But how I can make a namespace prefix to an xml-element? The only solution I found was this:

tester('xmlns:structure' :"http://test.ch/structure/1", 'ZH')

But this gives me the follwing output:

<tester xmlns:structure='http://test.ch/structure/1'>ZH</tester>

It's syntactical correct, but not nice to read when you have many nodes.

解决方案

You can do this (not sure it's what you want though)

import groovy.xml.StreamingMarkupBuilder
import groovy.xml.XmlUtil

def xmlBuilder = new StreamingMarkupBuilder()
writer = xmlBuilder.bind {
  mkp.declareNamespace( register: "http://www.test.ch/register/1" )
  mkp.declareNamespace( structure: "http://test.ch/structure/1" )
  'structure:structuralDataRoot' {
    'structure:tester'( 'ZH' )
    'structure:surveyYear'( 2001 )
    'structure:surfaceData' {
      'structure:houseSurfaceData' {
        'structure:creationDate'( '2001-01-01' )
        'structure:localFarmId' {
          'register:houseIdCategory'( 'token' )
          'register:houseId'( 'token' )
        }
      }
    }
  }
}

println XmlUtil.serialize( writer )

That code outputs:

<?xml version="1.0" encoding="UTF-8"?>
<structure:structuralDataRoot xmlns:register="http://www.test.ch/register/1" xmlns:structure="http://test.ch/structure/1">
  <structure:tester>ZH</structure:tester>
  <structure:surveyYear>2001</structure:surveyYear>
  <structure:surfaceData>
    <structure:houseSurfaceData>
      <structure:creationDate>2001-01-01</structure:creationDate>
      <structure:localFarmId>
        <register:houseIdCategory>token</register:houseIdCategory>
        <register:houseId>token</register:houseId>
      </structure:localFarmId>
    </structure:houseSurfaceData>
  </structure:surfaceData>
</structure:structuralDataRoot>
