如何在使用XmlSlurper解析xml时读取带连字符的属性名称(例如model_name)

import groovy.util.XmlSlurper

def xml = """
<root>
    <item model_name="Model A">
        <name>Item A</name>
    </item>
    <item model_name="Model B">
        <name>Item B</name>
    </item>
</root>
"""

def slurper = new XmlSlurper().parseText(xml)

slurper.item.each { item ->
    def modelName = item."@${'model-name'}"
    println "Model Name: $modelName"
}

Model Name: Model A
Model Name: Model B
