How to read xml file in groovy?

@dorothea_mohr 

There are several ways to read an XML file in Groovy. Here are a few options:

1. Using XmlSlurper: XmlSlurper is a class in Groovy that allows you to parse XML documents easily. Here's an example code snippet:

1

def xml = new XmlSlurper().parse(file)

In this example, "file" is a variable that contains the path to your XML file. Once you've parsed the XML document, you can access its elements and attributes like this:

1

xml.someElement.someAttribute

1. Using XmlParser: XmlParser is another class in Groovy that can be used to read XML documents. Here's an example code snippet:

1

def xml = new XmlParser().parse(file)

This code is similar to the XmlSlurper example above. The main difference is that XmlParser creates a tree representation of the XML document, which can be useful if you need to navigate through the document more carefully.

1. Using GPath: GPath is a language within Groovy that allows you to select elements from XML documents using a simple syntax. Here's an example code snippet:

1
2

def xml = new XmlSlurper().parse(file)
def someValue = xml.'**'.find{ it.name() == 'someElement' }.text()

In this example, GPath is used to select the "someElement" element from the XML document and extract its text content. The "**" notation means to search the entire document, recursively.
