Jenkinsfile XmlParser（）。parseText（xml_file）不适用于XML节点名称

Question

需要从某些XML文件中提取一些值。从Jenkins文件触发提取。以下代码在我的Jenkinsfile中可以正常工作：

    def xml_file_contents = new XmlParser().parseText(xml_file)
    def value_i_need_to_extract = xml_file_contents.children()[4].children()[0].children()[0].children()[0].text().toString()

但是，解析后的XML文件可能会在以后进行修改，因此通过XML节点名称而不是使用children（）方法进行遍历将是一个更好的主意。但是，每次我应用这样的内容：

    def value_i_need_to_extract = xml_file_contents.nodename.nodename.nodename.nodename.text().toString()

我收到以下错误：

    org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node remote

我已经尝试使用不同的XML文件和不同的节点名称遍历节点名称，但是结果始终是错误。

并且尽管我已经批准了Jenkins进程内脚本批准所需的所有安全功能，但仍会出现此错误。

说明问题的示例：

代码A：

def remote_repo = xml_file_contents.children()[3].children()[0].children()[0].children()[0]
echo 'Remote repository is:' + remote_repo.toString()

输出A：

Remote repository is:remote[attributes={}; value=[http://LAPTOP/svn/localrepo/app/component/RC]]

代码B：

def remote_repo = xml_file_contents.children()[3].children()[0].children()[0].children()[0].text()
echo 'Remote repository is:' + remote_repo.toString()

输出B：

Remote repository is:http://LAPTOP/svn/localrepo/app/component/RC

代码C：

def remote_repo = xml_file_contents.children()[3].children()[0].children()[0].remote.text()

输出C：

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node remote

您知道这种行为的可能原因吗？有没有一种方法可以通过节点名称遍历XML？

更新。

正在申请：

new XmlParser().parse(xml_file)

而不是：

new XmlParser().parseText(xml_file)

产生错误：
