如何使用groovy解析xml

我是groovy xml解析新手。我正在尝试解析下面的xml文件

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",

我让第一个孩子使用价值观 docParser.getElementsByTag("tr").first()

以下是我得到的错误:

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$0.call(Unknown Source)
    at CommonUtils.parseLRHTMLReport(jmeteragent.groovy:304)
    at CommonUtils$parseLRHTMLReport.call(Unknown Source)

以下是我迄今为止所做的工作:

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++
            }


        }
    }

}

我不知道如何绘制地图 tmpElement.children()
