如何使用 groovy 解析 xml

Question

我是 groovy xml 解析的新手。我正在尝试解析以下 xml 文件

<font face=Tahoma size=2>
   Team,<br/><br/>  Please find below the test summary details for the 'Test' execution.<br/><br/><b><U>Transaction Summary Table:</U></b><br/><br/>
   <table border=1 CELLPADDING =3 style='font-family:Tahoma;font-size:12'>

预期结果：

 [{
"transaction name":"1 /aumentum/", 
"AverageLatency ":"1648.0",
"Minimum latency":"1240",
"MaximumLatency ":"2900",
"AverageElapsedTime":"1907.0",
"MinimumElapsedTime":"1495",
"MaximumElapsedTime":"3140",
"TotalCount":"45",
"PassPercentage":"100.0"
},
{
"transaction name": "1 /aumentum/",
"AverageLatency ":"1648.0",
"Minimum latency":"1240",
"MaximumLatency ":"2900",
"AverageElapsedTime":"1907.0",
"MinimumElapsedTime":"1495",
"MaximumElapsedTime":"3140",
"TotalCount":"45",
"PassPercentage":"100.0"

}]

我得到了第一个 children 使用值 docParser.getElementsByTag("tr").first()

这是我得到的错误：

Exception thrown
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
    at org.jsoup.select.Elements.get(Elements.java:519)
    at org.jsoup.nodes.Element.child(Element.java:174)
    at org.jsoup.nodes.Element$child[=14=].call(Unknown Source)
    at CommonUtils.parseLRHTMLReport(jmeteragent.groovy:304)
    at CommonUtils$parseLRHTMLReport.call(Unknown Source)

这是我到目前为止所做的：

def transactiondetails12 = null
def iterator12 = 0
int count1 = 0
def violcounts = 0
def violations = null;

tmpElement = docParser.getElementsByTag("tr").first()
println tmpElement.children()
// tmpElement= tmpElement.child(0)
// println "#########tmpElement#########:" +tmpElement


for (element in tmpElement.children()) {
    if (iterator12 == 0) {
        // transactiondetails1 = "<table border=1 CELLPADDING =3 style='font-family:Tahoma;font-size:12'><tr><b><th bgcolor=#C0C0C0>"  +
        element.child(0).text().trim() + "</th><th bgcolor=#C0C0C0>" + element.child(2).text().trim() + "</th><th bgcolor=#C0C0C0>" +
                element.child(3).text().trim() + "</th><th bgcolor=#C0C0C0>" + element.child(4).text().trim() + "</th></b></tr>"
        iterator12 = 1;
        count1++;
        //  println "nqwlieufrh    2938ry    `9p23dhWCDNJ    p3fu89    Q2390RUD"+transactiondetails1
    } else {
        count1++;
        if (count1 <= 5) {

            //   println "iterator1iterator1iterator1iterator1"+iterator1++
            transactiondetails12 = transactiondetails12 + "<tr><td>" + element.child(0).text().trim() + "</td><td><center>" +
                    element.child(2).text().trim() + "</center></td><td><center>" +
                    element.child(3).text().trim() + "</center></td><td><center>" +
                    element.child(4).text().trim()
            println "transactiondetails12" + transactiondetails12
            //   println "3215463654156436212315465123011482145634217225445622341"+element.child(4).text().trim()
            String violation1 = element.child(1).text()
            // violation=Integer.valueOf(violation1)
            // violation=Integer.parseInt(violation1)

            //   if(violation1>=0)
            if (violation1.length() > 0) {
                violcounts++
            }


        }
    }

}

我不知道如何映射 tmpElement.children() 值。对此的任何建议都会有所帮助。提前致谢。

您提供的示例使用了对 HTML DOM 操作有用的 jsoup 库。您的问题的解决方案是使用正确的选择器来提取数据。

考虑以下示例：

def headers = docParser.select("tr > th").collect { it.text() }
def result = []

docParser.select("tr:has(td)").each { tr ->
    def obj = [:]
    tr.select("td").eachWithIndex { Element td, int i ->
        obj[headers[i]] = td.text()
    }
    result << obj
}

println JsonOutput.prettyPrint(JsonOutput.toJson(result))

docParser.select("tr > th").collect { it.text() } 收集 table header 并将它们存储为有序的 List<String>
docParser.select("tr:has(td)") 选择数据为
tr.select("td").eachWithIndex 在每一行内迭代，收集数据并通过索引 i
最后一行向控制台显示所需的输出

输出：

[
    {
        "TransactionName": "1 /aumentum/",
        "AverageLatency": "1648.0",
        "MinimumLatency": "1240",
        "MaximumLatency": "2900",
        "AverageElapsedTime": "1907.0",
        "MinimumElapsedTime": "1495",
        "MaximumElapsedTime": "3140",
        "TotalCount": "45",
        "PassPercentage": "100.0"
    },
    {
        "TransactionName": "T01_Aumentum_Home",
        "AverageLatency": "6.0",
        "MinimumLatency": "1",
        "MaximumLatency": "10",
        "AverageElapsedTime": "1956.0",
        "MinimumElapsedTime": "1490",
        "MaximumElapsedTime": "3806",
        "TotalCount": "213",
        "PassPercentage": "0.0"
    }
]

在这里你可以找到完整的 Groovy 脚本，我用它来试验你的例子：https://gist.github.com/wololock/651a536dff4e104ebba0eef69d4ac3ea
