在Groovy MarkupBuilder中使用命名空间

本文介绍了在Groovy MarkupBuilder中使用命名空间的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

<？xml version =1.0encoding =UTF-8 ？> < structure：structuralDataRoot xmlns：register =www.test.ch/register/1xmlns：structure =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'：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'：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：www.test.ch/register/1） mkp.declareNamespace（结构：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 =www.test.ch/register/1xmlns：structure =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="www.test.ch/register/1" xmlns:structure="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' :"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' :"test.ch/structure/1", 'ZH')

But this gives me the follwing output:

<tester xmlns:structure='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: "www.test.ch/register/1" ) mkp.declareNamespace( structure: "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="www.test.ch/register/1" xmlns:structure="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>
