用xslt在groovy中执行xml到html转换

分类: 技术问答 • 2022-07-04 20:06:35
问题描述：

我想将我的xml文件转换为html。 xslt代码正在工作，但我不知道如何在我的groovy脚本中执行转换。我想：用xslt在groovy中执行xml到html转换

import javax.xml.transform.TransformerFactory 
    import javax.xml.transform.stream.StreamResult 
    import javax.xml.transform.stream.StreamSource 
    import javax.xml.transform.Templates 

stage('make Changelog'){ 
    node('fetch'){ 
     dir('C:\\Jenkins_Slave_FETCH\\xsl_changelog') { 

      def xslt= readFile("C:\\Jenkins_Slave_FETCH\\xsl_changelog\\convert.xsl") 

      def transformer = TransformerFactory.newInstance().newTransformer(new StreamSource(new StringReader(xslt))) 

      def xml= readFile("C:\\Jenkins_Slave_FETCH\\xsl_changelog\\tmp.xml") 

      def html = new FileOutputStream("C:\\Jenkins_Slave_FETCH\\xsl_changelog\\Changelog.html") 

      transformer.transform(new StreamSource(new StringReader(xml)), new StreamResult(html)) 
     } 
    } 
}

但是这个代码导致以下错误：

[Pipeline] stage 
[Pipeline] { (make Changelog) 
[Pipeline] node 
Running on DEGTW6216_Slave_FETCH in C:\Jenkins_Slave_FETCH\workspace\Gen7000\test 
[Pipeline] {

Running in C:\Jenkins_Slave_FETCH\xsl_changelog 
[Pipeline] { 
[Pipeline] readFile 
[Pipeline] readFile 
[Pipeline] } 
[Pipeline] // dir 
[Pipeline] } 
[Pipeline] // node 
[Pipeline] } 
[Pipeline] // stage 
[Pipeline] End of Pipeline

是否有人知道如何解决这个问题？

更好的编写/调试任何groovy IDE的正确代码。除了明显的例外，它将更容易修复它们。你可以使用groovy二进制的'groovyColsole'。我认为你提供的错误说管道无法显示你的groovy代码中发生的错误。所以，我们不能解决它，因为我们没有看到它） – daggett

我解决了这个问题。看起来jenkins的安全设置对于groovy中的xsl转换并不合适。所以我在PowerShell中执行转换，一切正常。

你可以在这里找到一些可能的解决方案：https://github.com/jenkinsci/pipeline-plugin/blob/f31f8fda473e4910f344afb50b0c95844825b7c9/TUTORIAL.md#serializing-local-variables

您的解决方案可能会是你的变压器和HTML变量分拆成另一种功能，并添加注释@NonCPS，这将确保它不会被序列化。

缺点是你不能在NonCPS函数中调用步骤，所以你必须在主jenkinsfile阶段加载你的文件，然后把文件的字符串传递给一个函数。

我还没有真正尝试过这一点，因为我没有你的文件，但功能可能是这样的：

@NonCPS 
def xmlToHtml(xslt, xml) { 
    def transformer = TransformerFactory.newInstance().newTransformer(new StreamSource(new StringReader(xslt))) 
    def html = new FileOutputStream("C:\\Jenkins_Slave_FETCH\\xsl_changelog\\Changelog.html") 
    transformer.transform(new StreamSource(new StringReader(xml)), new StreamResult(html)) 
}
