解析 xml 并在 groovy 中提取子元素的特定属性

Question

>我有以下xml作为字符串：(在这里使用时髦的操场进行快速执行：https://groovy-playground.appspot.com/(

string = """<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

            </channels>

"""

我想从标签"服务"中提取类型"oracle"，这是标签的属性，总是收到错误，这是我尝试运行的代码：

def xmlParser = new XmlParser().parseText(string)
agentPlatform = xmlParser.services.service.attribute("type")
println agentPlatform

这样做的正确形式是什么？

找到答案：

def xmlParser = new XmlParser().parseText(string)
results = xmlParser.services[0].service[0].@type
println results //Oracle
