在Jenkins管道中解析XML文件

我有一个XML文件，我想将其用作管道脚本的输入。问题是XMLParser不可序列化，因此我将其放在NonCPS函数中，但是因此丢失了Node对象。

这是管道脚本：

def buildPlanPath = 'C:\\buildPlan_test.xml'
@NonCPS
groovy.util.Node getBuildPlan(path) {
    new XmlParser().parseText(readFile(path))
}
node {
    //def buildPlan = new XmlParser().parseText(readFile(buildPlanPath))
    groovy.util.Node buildPlan = getBuildPlan(buildPlanPath)
    println buildPlan.getClass()
    println buildPlan
    println buildPlan.branch
}

这是一个输入样本：

<branch name='mybranch'>
    <stage>
        <job name='job11' />
        <job name='job12' />
    </stage>
    <stage>
        <job name='job21' />
        <job name='job22' />
        <job name='job23' />
    </stage>
    <stage>
        <job name='job31' />
    </stage>
</branch>

结果如下：

Started by user admin
[Pipeline] node
Running on master in C:\Jenkins\workspace\pipeline-develop
[Pipeline] {
[Pipeline] readFile
[Pipeline] echo
class java.lang.String
[Pipeline] echo
<branch name='mybranch'>
  <stage>
    <job name='job11' />
    <job name='job12' />
  </stage>
  <stage>
    <job name='job21' />
    <job name='job22' />
    <job name='job23' />
  </stage>
  <stage>
    <job name='job31' />
  </stage>
</branch>
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

我正在使用Jenkins 2.7和管道2.1，这是最新的。

回答：

您可以使用XmlSlurper，它对我有用。

def xmlText = new XmlSlurper().parse(MyURL)
xmlText.data.artifact.each {******
