I need to add @ attribute to the root element of XML fragment in Groovy. I want to use XmlSlurper. How to do it? Adding elements is easy.

推荐答案

在Groovy控制台中运行它以验证它是否正常运行

Run this in the Groovy console to verify that it works

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
