Question

下面是我的HTML。我的要求是找到input代码id值，并在label **for**属性中放置相同的ID值。喜欢 <label for="beneficiary.trustName">

<div> 
    <div class="lbl">
        <label>
            <span id=Trust Name" class="required">*</span>
            Trust Name
        </label>
    </div>
    <div class="input">
        <input id="beneficiary.trustName" class="inputlgbeneficiary-name" type="text"
        name="beneficiary.trustName" value="" size="30" maxlength="30" onkeypress="return(event);">
    </div>
</div>

这样的事情会发生。虽然错误处理不存在。您可以自己添加该部分。

Document doc = Jsoup.parse(content);

Elements inputContainers = doc.getElementsByClass("input");
for(Element inpContainer : inputContainers) {
    Element labelContainer = inpContainer.siblingElements().get(0);

    Element label = labelContainer.getElementsByTag("label").get(0);
    Element input = inpContainer.getElementsByTag("input").get(0);

    label.attr("for", input.id());
}

System.out.println(doc);

查找<label>并根据<input />标记标识
