Question

尝试使用html agility pack获取此处服务数量的值

<span class="recipe-ingredients__header__toggles">
    <span class="ready-in-time__container">
        <span class="ready-in-time">3 h 30 m</span>
        <span class="icon--stats-clock"></span>
    </span>

<meta id="metaRecipeServings" itemprop="recipeYield" content="8">

<a href="" id="servings-button" popup-trigger="servingsSection">
    <span class="servings-count" ng-class="{'active': servingsSection_showing}"><span ng-bind="adjustedServings" class="ng-binding">8</span><span class="servings-count__desc" ng-class="{'active': servingsSection_showing}"> servings</span></span>

    <span class="icon--adjust-servings" ng-class="{'active': servingsSection_showing}"></span>
</a>

    <a href="" id="nutrition-button" popup-trigger="nutritionSection">
        <span class="calorie-count" ng-class="{'active': nutritionSection_showing}"><span>562</span> <span class="calorie-count__desc" ng-class="{'active': nutritionSection_showing}"> cals</span></span>
        <span class="icon--nutrition-info" ng-class="{'active': nutritionSection_showing}"></span>
    </a>

具体来说，我正在看标签

 <span ng-bind="adjustedServings">

具有值＆＃34; 8＆＃34;。我在这里得到了所有其他价值，但似乎无法想出这一点。在这种情况下，我只想要整数8。

Answer 1

SelectSingleNode("//span[@ng-bind='adjustedServings']").InnerText

应该做的伎俩。如果您有多个这些span使用SelectNodes，请在foreach中使用它并分别访问节点上的InnerText。

没有尝试编译，如果您遇到错误，我会对其进行编辑

使用html敏捷性来获取此节点的值
