Question

我必须使用loadrunner分别捕获<select name="fromPort">和<select name="toPort">中的选项值以进行关联。

我将正则表达式写为

<select name="fromPort" class="form-inline">(.+?)</select>

从头开始捕获，但表明没有匹配项。

<form action="reserve.php" method="post">
        <select name="fromPort" class="form-inline">
            <option value="Paris">Paris</option>
            <option value="Philadelphia">Philadelphia</option>
            <option value="Boston">Boston</option>
            <option value="Portland">Portland</option>
            <option value="San Diego">San Diego</option>
            <option value="Mexico City">Mexico City</option>
            <option value="São Paolo">São Paolo</option>
        </select>
        <p>
        <h2>Choose your destination city:</h2>
        <select name="toPort" class="form-inline">
            <option value="Buenos Aires">Buenos Aires</option>
            <option value="Rome">Rome</option>
            <option value="London">London</option>
            <option value="Berlin">Berlin</option>
            <option value="New York">New York</option>
            <option value="Dublin">Dublin</option>
            <option value="Cairo">Cairo</option>
        </select>
        <p></p>
        <div class="container">
            <input type="submit" class="btn btn-primary" value="Find Flights"/>
        </div>
    </form>

当我尝试使用notepad ++时，有一个复选框可以选择何时捕获多行响应。当我检查它时，相同的正则表达式正在工作。enter code here

Answer 1

您可以尝试

好吧，我要做的是

使用此方法从选择匹配的选择标签中提取所有选项

(?:<select name="(fromPort|toPort)" class="form-inline">\s+)([\w\W]+?)(?=\s+<\/select>)
然后将每个选项作为单个元素拆分为一个数组。
比使用此正则表达式从每个选项中提取的值还要多。

(?<=\s*?<option value=")(.*?)(?=">.*?<\/option>)

let str =`<form action="reserve.php" method="post">
        <select name="fromPort" class="form-inline">
            <option value="Paris">Paris</option>
            <option value="Philadelphia">Philadelphia</option>
            <option value="Boston">Boston</option>
            <option value="Portland">Portland</option>
            <option value="San Diego">San Diego</option>
            <option value="Mexico City">Mexico City</option>
            <option value="São Paolo">São Paolo</option>
        </select>
        <p>
        <h2>Choose your destination city:</h2>
        <select name="toPort" class="form-inline">
            <option value="Buenos Aires">Buenos Aires</option>
            <option value="Rome">Rome</option>
            <option value="London">London</option>
            <option value="Berlin">Berlin</option>
            <option value="New York">New York</option>
            <option value="Dublin">Dublin</option>
            <option value="Cairo">Cairo</option>
        </select>
        <p></p>
        <div class="container">
            <input type="submit" class="btn btn-primary" value="Find Flights"/>
        </div>
    </form>`
    
let selectAllOption = str.match(/(?<=<select name="(fromPort|toPort)" class="form-inline">\s+)[\w\W]+?(?=\s+<\/select>)/g);

let splitedOptions = selectAllOption.map(e=>e.split('\n'))
let finalValues = splitedOptions.map(e=>{
  return e.map(ele=>{
    return ele.match(/(?<=\s*?<option value=")(.*?)(?=">.*?<\/option>)/g)
  })
})
console.log(finalValues);

考虑到您在房屋的另一侧涉及多个类似的标签，我的回答不太优雅。我建议备份，以\“ fromPort” class = \“ form-inline \” \ n“或\” toPort“ class = \” form-inline \“ \ n”的LB条件捕获到结束标签“ \ n”

您将得到两个包含选项值的字符串变量，例如“ Correlated_from”和“ Correlated_to”。接下来是转换为数组结构。

大概有十二种方法可以将字符串分开，但我建议使用一个在换行符上断开的函数，将子字符串中的第一个“ \ t \ t”字符跳转，以节省字符串之间的值和下一个“ <”字符。如前所述，可能有十二种方法可以使用定义的模式分解此字符串，以找到您感兴趣的子字符串。

通过遵循标准的LoadRunner伪数组结构，这为使用标准LoadRunner函数分配伪数组中的变量-lr_paramarr_ *函数集提供了便利。

我使用 LB="select id="xxxx"" 和 RB=" 提取选择

然后使用类似下面的东西来获取所有选项（如果我想随机化提交脚本的哪个，或者我选择已经选择的一个，如果我想提交默认选择是什么。每当我需要使用复杂的正则表达式我通常将一个测试用例硬编码到一个临时测试操作中，以便在运行实际应用程序之前测试逻辑。

    int matchCt, ord;
