Question

我有一个很大的XML数据集，从中我只需要某些值。具体来说，我需要一个jmeter测试脚本的断言失败消息。

这是我的XML，所需结果是一个包含2行的表。第一行具有错误消息的三列，第二行具有“空”的三列：

 @SpringBootApplication
        (
                scanBasePackages = {
                        "com.package1",
                        "com.package2"
                },
                exclude = {org.springframework.boot.sample.class}
        )

我一直在研究W3Schools的示例，但是由于我的XML结构不同，所以我一直在尝试根据自己的需要对其进行修改。

我的问题是，当我需要它提供@SpringBootApplication(exclude= {com.package1.class}) public class MySpringConfiguration {}节点值时，我的HTML表的每个单元格都为“ null”。因此，我认为我错误地检索了XML值（在for循环中）。我对Xpath有一定的经验，但是没有通过Javascript / HTML获得节点值。

这是我的HTML / Javascript

<?xml version="1.0" encoding="UTF-8"?>
<testResults version="1.2">
<httpSample ts="1555683457534" lb="What is cocktail?">
  <assertionResult>
    <name>Intent</name>
    <failure>true</failure>
    <error>false</error>
    <failureMessage>ERROR: THIS IS THE TEXT I NEED IN THE TABLE</failureMessage>
  </assertionResult>
  <assertionResult>
    <name>Input</name>
    <failure>true</failure>
    <error>false</error>
    <failureMessage>ERROR: THIS IS THE TEXT I NEED IN THE TABLE</failureMessage>
  </assertionResult>
  <assertionResult>
    <name>Entity</name>
    <failure>true</failure>
    <error>false</error>
    <failureMessage>ERROR: THIS IS THE TEXT I NEED IN THE TABLE</failureMessage>
  </assertionResult>
</httpSample>
<httpSample ts="1555683467885" lb="What is coconut?">
  <assertionResult>
    <name>Intent</name>
    <failure>false</failure>
    <error>false</error>
    <failureMessage></failureMessage>
  </assertionResult>
  <assertionResult>
    <name>Input</name>
    <failure>false</failure>
    <error>false</error>
    <failureMessage></failureMessage>
  </assertionResult>
  <assertionResult>
    <name>Entity</name>
    <failure>false</failure>
    <error>false</error>
    <failureMessage></failureMessage>
  </assertionResult>
</httpSample>
</testResults>

很抱歉，如果这是一个罗y的问题，应该很简单

解析XML的一种方法是使用XSLT转换XML并提取数据。

我将XML和XSLT作为脚本放置在HTML中，但是您可以从外部资源加载它们。

function transformXML(xmlText, xsltText) {

  if (!(window.DOMParser && window.XSLTProcessor)) {
    return xmlText;
  }
  
  // Load the XSLT into a document
  var xsltDoc = new DOMParser().parseFromString(xsltText, "text/xml");

  var xslt = new XSLTProcessor();
  xslt.importStylesheet(xsltDoc);

  var xml = new DOMParser().parseFromString(xmlText.trim(), "text/xml");

  var transformedXml = xslt.transformToDocument(xml);

  return (!transformedXml) ? xmlText :
    new XMLSerializer().serializeToString(transformedXml);
}

function fnProcess(){
  
  var xmlText = $("#xml").text();
  var xslText = $("#xslt").text();
  var resultText = transformXML(xmlText,xslText);
  
  $("#result").html(resultText);
  
}

#result {padding:20px;}
