Question

我正在使用Xpath Extractor从XML响应中找出节点值，但每次执行时Jmeter都会抛出错误，并出现以下错误：

jmeter.extractor.XPathExtractor：处理时发生TransformerException （（// * [local-name（）='RequestID']）[2] / text（）） - 1

Jmeter中使用的xpath表达式：(//*[local-name() = 'RequestID'])[2]/text()

我在线检查了我的xpath表达式并且它有效并返回了预期的值。不确定jmeter有什么问题。

这是xml：

Answer 1

您可以使用Beanshell Post Processor

从变量中减去1

假设您在XPath Extractor中使用RequestID作为参考名称，并且正在使用XPath获取RequestID

(//*[local-name() = 'RequestID'])[2]/text()

或 // NS2：请求ID /文本（）

Next Beanshell代码将允许您操作变量

int requestId = Integer.parseInt(vars.get("RequestID"));
requestId = requestId--;
vars.put("RequestID", String.valueOf(requestId));

Jmeter xpath提取器不为有效的Xpath提供节点值
