如何使用Groovy添加XML屬性？

Question

我需要在Groovy的XML片段的根元素中添加@屬性。我想用XmlSlurper。怎麼做？添加元素很簡單。

Answer 1

運行這在Groovy的控制檯，以驗證它的工作原理

import groovy.xml.StreamingMarkupBuilder 

// the original XML 
def input = "<foo><bar></bar></foo>" 

// add attributeName="attributeValue" to the root 
def root = new XmlSlurper().parseText(input) 
root.@attributeName = 'attributeValue' 

// get the modified XML and check that it worked 
def outputBuilder = new StreamingMarkupBuilder() 
String updatedXml = outputBuilder.bind{ mkp.yield root } 

assert "<foo attributeName='attributeValue'><bar></bar></foo>" == updatedXml 

Answer 2

增加一個屬性是一樣的閱讀它：

import groovy.xml.StreamingMarkupBuilder 

def input = ''' 
<thing> 
    <more> 
    </more> 
</thing>''' 

def root = new XmlSlurper().parseText(input) 

root.@stuff = 'new' 

def outputBuilder = new StreamingMarkupBuilder() 
String result = outputBuilder.bind{ mkp.yield root } 

println result 

會給你：

<thing stuff='new'><more></more></thing>
