Jenkins XmlParser reports No such field found for attribute for root node

问题

I have a project that has the following XML file (config.xml for a Cordova project) ...

    <?xml version='1.0' encoding='utf-8'?>
    <widget android-versionCode="16" id="com.mycomp.myapp" ios-CFBundleVersion="15" version="1.3.0.b4" windows-packageVersion="1.2.6.0" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
        <name>My App</name>
        <description>My app description</description>
        <author>mycom.com.au</author>
           ....

All I want to do is read the value of the version attribute (to give me the string 1.3.0.b4) of the root element (widget). Following the example here where it says to use the .@ to get an attribute.

I have the following in my Jenkins file script...

        script {
              def xml = readFile "${env.WORKSPACE}/config.xml"
              def rootNode = new XmlParser().parseText(xml)
              def version = rootNode.@version
              echo 'version is...'
              echo version

But when I run it, I get the following error..

        org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node version
        at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.unclassifiedField(SandboxInterceptor.java:425)

        at com.cloudbees.groovy.cps.sandbox.SandboxInvoker.getAttribute(SandboxInvoker.java:37)

I have tried rootNode.@version (as above) rootNode[0].@version and rootNode[3].@version but nothing works.

Does anyone have any idea of whats wrong with the above?

Thanks in advance

[EDIT1]

If I use the following...

def xml = readFile "${env.WORKSPACE}/config.xml"
def rootNode = new XmlParser().parseText(xml)
def version = rootNode.text()
echo 'version is...'
echo version

it prints out My app description which is a bit weird (it jumps down to the description node)

[EDIT2]

I tried using the following..

 def rootNode = new XmlSlurper().parse("${env.WORKSPACE}/config.xml")
 def version = rootNode.@'version'

but I still get a similar error...

If I call echo rootNode.text(), once again it seems to just print out the contents of the first 3 tags inside the main ,widget tag, i.e. My AppMy app descriptionmycom.com.au.

Edit:

I tested some more in context of being able to also modify the attribute, and found out when using the [] access, the @ selector for attributes actually works. It seems this leads to use different methods under the hood which you can approve in jenkins (getAtand putAt) .

We can simply use

def rootNode = new XmlParser().parseText(xml)
println rootNode['@version']

Original Answer:

There seems some bug regarding the direct access to the attributes with the @ selector on the groovy.util.Node object with the script sandbox.

A workaround is to use the .attributes() method to get the full Map of attributes, and access the value via the key like the following:

def rootNode = new XmlParser().parseText(xml)
println rootNode.attributes()['version']

This will fail the first run and promt you to approve the use of method groovy.util.Node attributes, but once approved will work.
