【翻译】用Groovy来更新XML

I'm newbie in Groovy and have to accomplish a task for some Jenkins configuration. Please,help me with xml parsing. Just in order to simplify the problem(originally it's a huge Jenkins config.xml file),let's take:

我是Groovy新手。我要完成一项Jenkins配置的任务。请教我解析xml。为了简述问题，下面只是截取了一部分Jenkins的配置文件config.xml:

def?input?=?'''
??????????????<shopping>
??????????????????<category>
??????????????????????<item>Pen</item>
??????????????????????<color>Red</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Pencil</item>
??????????????????????<color>Black</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Paper</item>
??????????????????????<color>White</color>
??????????????????</category>
??????????????</shopping>
????'''

The target is to change color for Pen only.

目标只是改变Pen的颜色。

I'm trying:

我尝试：

def?root?=?new?XmlParser().parseText(input)def?supplies?=?root.category.find{?it.text()?==?'Pen'?}?supplies.parent().color.value()?=?'Changed'

Looks so simple but I'm totally lost :( Appreciate any help.

看起来简单我却被搞得一头雾水了。求救。

Almost there...

几乎要实现了。。。

def?root?=?new?XmlParser().parseText(input)
def?supplies?=?root.category.find{?it.item.text()?==?'Pen'?}
supplies.color[0].value?=?'Changed'

The thing to note is that color is a Node List whose first node is a text node

要注意的是color是一个Node列表，而其第一个节点是文本节点

....Or use?XmlSlurper?to simplify usage of?color[0]?and?text().

或者使用 XmlSlurper 去简化 color[0] 和 text() 。

def?root?=?new?XmlSlurper().parseText(input)
def?supplies?=?root.category.find{?it.item?==?'Pen'?}
supplies.color?=?'Changed'

完整代码一：

import?groovy.xml.XmlUtil
def?input?=?'''
??????????????<shopping>
??????????????????<category>
??????????????????????<item>Pen</item>
??????????????????????<color>Red</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Pencil</item>
??????????????????????<color>Black</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Paper</item>
??????????????????????<color>White</color>
??????????????????</category>
??????????????</shopping>
????'''
????
def?root?=?new?XmlParser().parseText(input)
def?supplies?=?root.category.find{?it.item.text()?==?'Pen'?}
supplies.color[0].value?=?'Changed'


//println?root.toString()
println?XmlUtil.serialize(root)

完整代码二：

import?groovy.xml.XmlUtil
def?input?=?'''
??????????????<shopping>
??????????????????<category>
??????????????????????<item>Pen</item>
??????????????????????<color>Red</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Pencil</item>
??????????????????????<color>Black</color>
??????????????????</category>
??????????????????<category>
??????????????????????<item>Paper</item>
??????????????????????<color>White</color>
??????????????????</category>
??????????????</shopping>
????'''
????
def?root?=?new?XmlSlurper().parseText(input)
def?supplies?=?root.category.find{?it.item?==?'Pen'?}
supplies.color?=?'Changed'


//println?root.toString()
println?XmlUtil.serialize(root)
