Question

我有问题能够将节点添加到节点子节点的0索引。

我能够将一个节点追加到最后，但无法弄清楚如何在前面找到一个节点。

我的代码目前看起来像这样。

def setupProjectXML(workspace, environment, client) {
    def projectFile = new XmlParser().parse(new File("${workspace}/jenkinsProject.xml"))

    projectFile.appendNode("set", [name : "m4"])
    projectFile.appendNode("set", [name : "universalM4"])
    projectFile.appendNode("set", [name : "restoreState"])
    projectFile.appendNode("set", [name : "staging"])

    println(projectFile.toString())
}

我尝试了一些不同的方式使用New Node（）并为NodeList添加，但是这会在我使用Node构造函数的时候崩溃脚本。

此错误是

Answer 1

def xml = new XmlParser().parseText('''<a><b c="d"/></a>''')
println groovy.xml.XmlUtil.serialize(xml)

xml.children().add(0, new Node(null, 'set', [x:'y'], 'text'))
println groovy.xml.XmlUtil.serialize(xml)

输出：

<?xml version="1.0" encoding="UTF-8"?><a>
  <b c="d"/>
</a>

<?xml version="1.0" encoding="UTF-8"?><a>
  <set x="y">text</set>
  <b c="d"/>
</a>

我得到了它。

def setupProjectXML(workspace, environment, client) {
    def projectFile = new XmlParser(false,true).parse(new File("${workspace}/jenkinsProject.xml"))
    projectFile.appendNode("set", [name : "m4"])
    projectFile.appendNode("set", [name : "universalM4"])
    projectFile.appendNode("set", [name : "restoreState"])
    projectFile.appendNode("set", [name : "staging"]) projectFile.children().get(0).replaceNode(projectFile.children().get(projectFile.children().size()-1))
projectFile.children().get(1).replaceNode(projectFile.children().get(projectFile.children().size()-2))
projectFile.children().get(2).replaceNode(projectFile.children().get(projectFile.children().size()-3))
projectFile.children().get(3).replaceNode(projectFile.children().get(projectFile.children().size()-4))

FileWriter fileWriter = new FileWriter("${workspace}/jenkinsProject.xml")
XmlNodePrinter nodePrinter = new XmlNodePrinter(new PrintWriter(fileWriter))
nodePrinter.setPreserveWhitespace(true)
nodePrinter.print(projectFile)
}

这是一种丑陋的方式，我不得不在我的xml类中添加空节点以用于替换。仍然不确定为什么我不能调用新的Node（）。
