我的产品网站中有html页面，我想解析文档并从html页面获取产品版本。
html页面如下所示：
<html>
.......
.......
<body>
.......
.......
<div id='version_info'>
<div class="product-version">
<div class="product-title">Name of the product 1:</div><div class="product-value">ver_123</div>
</div>
<div class="product-version">
<div class="product-title">Name of the product 2:</div><div class="product-value">ver_456</div>
</div>
<div class="product-version">
<div class="product-title">Name of the product 3:</div><div class="product-value">ver_845</div>
</div>
<div class="product-version">
<div class="product-title">Name of the product 4:</div><div class="product-value">ver_146</div>
</div>
</div>
.......
.......
</body>
.......
.......
</html>
如何grep文档并形成类似这样的字符串？ productname1 = ver_123，productname2 = ver_456，productname3 = ver_845等
答案 0 :(得分：1)
我已经处理过这个特定的HTML文件，结果我在变量result下得到了所需变量的字典
注意：
1. 请在剧本中更改html文件的路径。
2。这个特定的剧本适合这个HTML示例。有关进一步的要求和改进，请提供HTML。
