在html中找到body标记结束的最佳方法-bestwaytofindendofbodytaginhtml

I'm not sure I'm understanding you, but do you mean this?

我不确定我是否理解你,但你的意思是这个吗?

// Given an HTML document in "htmlDocument", and new content in "newContent"
string newHtmlDocument = htmlDocument.Replace("", newContent+"");

And it's probably obvious I don't know c#... You'd probably want to make the "body" tag case insensitive via regexps.

而且很明显我不知道c#...你可能想通过regexp使“body”标签不区分大小写。

I would recommend to use HtmlAgilityPack to parse the html into DOM and work with it.

我建议使用HtmlAgilityPack将html解析为DOM并使用它。

public string AddImageLink(string emailBody,string imagePath)
{
    try
    {
    HtmlDocument doc = new HtmlDocument();
    doc.LoadHtml(emailBody);

    HtmlNode node = doc.DocumentNode.SelectSingleNode("//body");

    // get body using xpath query ("//body")
    // create the new node ..

    HtmlNodeCollection LinkNode = new HtmlNodeCollection(node);
    //

    HtmlNode linkNode = new HtmlNode(HtmlNodeType.Element,doc,0);
    linkNode.Name = "A";
    linkNode.Attributes.Add("href","www.splash-solutions.co.uk");


    HtmlNode imgNode = new HtmlNode(HtmlNodeType.Element,doc,1);
    imgNode.Name = "img";
    imgNode.Attributes.Add("src",imagePath);

    //appending the linknode with image node
    linkNode.AppendChild(imgNode);

    LinkNode.Append(linkNode);

    //appending LinkNode to the body of the html
    node.AppendChildren(LinkNode);


    StringWriter writer = new StringWriter();
    doc.Save(writer);
    emailBody = writer.ToString();
    return emailBody;
}

If the HTML files are valid XHTML you could always use the XmlDocument class to interpret it. You could then easily look for the body element and append a child element to it. This would place the element right before the closing tag.

如果HTML文件是有效的XHTML,您可以始终使用XmlDocument类来解释它。然后,您可以轻松查找body元素并向其添加子元素。这会将元素放在结束 标记之前。

I'm not sure whether the example content you want to add after the tag is the correct one or not, but if it is, I'm seeing two problems:

我不确定您要在标签之后添加的示例内容是否正确,但如果是,我会看到两个问题:

1. The Google Analytics code should be added just before the end tag, not the opening tag. That ensures that you don't have to wait for it to load before loading your own code.

应在结束标记之前添加Google Analytics代码,而不是在开始标记之前添加。这可确保您在加载自己的代码之前不必等待它加载。

2. If you're adding some other Javascript, why not add that in an external file, and execute that one onload instead?

如果你要添加一些其他的Javascript,为什么不在外部文件中添加它,并执行那个onload呢?

Hope that's of some help :)
