Html Agility Pack：查找注释节点 [英] Html Agility Pack: Find Comment Node

问题描述

基本上，我正在寻找XPATH \\div [@ class ='PricingInfo']，但该div节点正在通过Javascript写入DOM。

因此，当我通过Html Agility包加载页面时，无法找到上面提到的XPATH。

事实证明，在某个特定脚本块我想解析。

 <！ - 模块328购买选项表 - > 
< script type =text / javascriptlanguage =JavaScript> 
 var data = {
 price：30.00 
} 
< / script> 
  

对于这个网站，有很多脚本块，所以我需要通过查找来缩小范围这个自动生成的注释<！ - 模块328买入选项表 - > ，并且该节点的同级将是正确的脚本块。

关于如何搜索特定评论然后获取相邻脚本块的任何想法？

谢谢！ p>

解决方案

  htmlDoc.DocumentNode.SelectSingleNode（// comment（）[contains（。，'购买选项'）] / following-sibling :: script）
  

I am scraping a website that uses Javascript to dynamically populate the content of a website with the Html Agility pack.

Basically, I was searching for the XPATH "\\div[@class='PricingInfo']", but that div node was being written to the DOM via Javascript.

So, when I load the page through the Html Agility pack the XPATH mentioned above cannot be found.

It turns out there is a comment before a particular script block I want to parse.

<!--Module 328 Buying Options Table-->
<script type="text/javascript" language="JavaScript">
    var data = {
        price: 30.00
    }
</script>

For this site, there are many script blocks and so I would need to narrow it down by the finding this auto-generated comment <!--Module 328 Buying Options Table--> and the sibling of that node would be the correct script block.

Any idea on how I can search for a particular comment and then just get the adjacent script block?

Thank you!

解决方案

htmlDoc.DocumentNode.SelectSingleNode("//comment()[contains(., 'Buying Options')]/following-sibling::script")
