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