如何使用java将jmeter jtl httpSample/httpSample子值替换为父值答案

【问题标题】：How to replace jmeter jtl httpSample/httpSample subchild value with parent value using java如何使用java将jmeter jtl httpSample/httpSample子值替换为父值
【发布时间】：2019-09-06 04:55:17
【问题描述】：

我尝试使用标准 jmeter 报告模板 XSL(jmeter-results-detail-report_21.xsl) 生成 jmeter 报告，但不知何故，报告无法将 httpSample/httpSample 的子子项显示为 httpSample 的细分。

是否有将子 httpSample/httpSample 结果显示为其父 httpSample 的细分？

我有一个想法，将子 lb 值替换为其父 lb 值，以使其独一无二。但是我是 java/regex/XSL 的新手，我该怎么做呢？

below is original jtl

expected result as below. It's will be few hundred thousand row need to be replace. Is there any way to replace it?

【问题讨论】：

您最好不要在这里使用正则表达式，而应该使用 XML 解析器（Java 有许多很好的库可以做到这一点）。
你好，蒂姆，Java 是个好主意。但是 XML 解析器如何知道 httpSample 有子子项并用它的父 lb 值替换。并非所有的 httpSample 都有子标签，只有那些 httpSample 包含子标签的才会被父标签替换。

标签： java regex xml jmeter xml-parsing

【解决方案1】：

也许，正则表达式不是解决这个问题的最佳方法，因为它看起来相当复杂。

话虽如此，父母在行首有两个空格，而“子孩子”似乎有四个，如果你愿意，你可以将其用作左边界，并设计任何你必须的表达式，例如：

^\s{2}<httpSample\s+.*?lb="(\S*).*[\r\n]^\s{4}<httpSample\s+.*?lb="([^"]*)"

只是一个例子。

    public static void main(String[] args){

晚安，艾玛，谢谢你指导我的逻辑。但是我如何用我们为 matcher.group(1) + " " + matcher.group(2) 获得的值替换 httpSample/httpSample lb 值；
