在 html 中查找 body 标记结尾的最佳方法

发布于 2024-07-29 03:30:59 字数 970 浏览 13 评论 0原文

我正在编写一个程序来向html文件添加一些代码

我将使用一系列indexof和循环来查找本质上是“”X的内容（其中 X 是我正在寻找的位置）

我想到可能有一种更雄辩的方式来做到这一点

，有人有任何建议吗？

目前的样子

<body onLoad="JavaScript:top.document.title='Abraham L Barbrow'; if (self == parent) document.getElementById('divFrameset').style.display='block';">

完成后应该是什么样子

<body onLoad="JavaScript:top.document.title='Abraham L Barbrow'; if (self == parent) document.getElementById('divFrameset').style.display='block';">
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-9xxxxxx-1");
pageTracker._trackPageview();
} catch(err) {}</script>

I'm writing a program to add some code to html files

I was going to use a series of indexof and loops to find what is essentially ""X
(where X is the spot im looking for)

It occurred to me that there might be a more eloquent way of doing this

does anyone have any suggestions.

what it looks like currently

<body onLoad="JavaScript:top.document.title='Abraham L Barbrow'; if (self == parent) document.getElementById('divFrameset').style.display='block';">

what it should look like when im done

<body onLoad="JavaScript:top.document.title='Abraham L Barbrow'; if (self == parent) document.getElementById('divFrameset').style.display='block';">
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-9xxxxxx-1");
pageTracker._trackPageview();
} catch(err) {}</script>

我不确定我是否理解你的意思，但你是这个意思吗？

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

很明显我不懂 C#...您可能想通过正则表达式使“body”标记不区分大小写。

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

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

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

我建议使用 HtmlAgilityPack 将 html 解析为 DOM 并使用它。

原来分手还会想你 2024-08-05 03:30:59

如果 HTML 文件是有效的 XHTML，您始终可以使用 XmlDocument 类来解释它。然后，您可以轻松查找 body 元素并向其附加一个子元素。这会将元素放置在结束标记之前。

我不确定您要在标记后添加的示例内容是否正确，但如果是，我会看到两个问题：

Google Analytics 代码应添加在 结束标记之前，而不是开始标签。这确保您不必等待它加载即可加载您自己的代码。
如果您要添加一些其他 javascript，为什么不将其添加到外部文件中，然后执行 onload 呢？

希望这对您有所帮助:)

这就是我得到的，

请随意提出建议

 private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog OFD = new OpenFileDialog();
            OFD.Multiselect = true;
            OFD.Filter = "HTML Files (*.htm*)|*.HTM*|" +
          "All files (*.*)|*.*";

            if (OFD.ShowDialog() == DialogResult.OK)
            {
                foreach (string s in OFD.FileNames)
                {
                    Console.WriteLine(s);
                    AddAnalytics(s);
                }
                MessageBox.Show("done!");
            }
        }
        private void AddAnalytics(string filename)
        {

            string Htmlcode = "";
            using (StreamReader sr = new StreamReader(filename))
            {

            }
            if (!Htmlcode.Contains(textBox1.Text))

                using (StreamWriter sw = new StreamWriter(filename))
                {
                    sw.Write(Htmlcode);
                }
            }
        }

        private string CreateCode(string Number)
        {
            StringBuilder sb = new StringBuilder();
            sb.AppendLine();
            sb.AppendLine("<script type=\"text/javascript\">");
            sb.AppendLine("var gaJsHost = ((\"https:\" == document.location.protocol) ? \"https://ssl.\" : \"http://www.\");");
            sb.AppendLine("document.write(unescape(\"%3Cscript src='\" + gaJsHost + \"google-analytics.com/ga.js' ");
            sb.AppendLine("<//script>");
            sb.AppendLine("<script type=/\"text//javascript/\">");
            sb.AppendLine("try {");
            sb.AppendLine(string.Format("var pageTracker = _gat._getTracker(/\"{0}/\");", Number));///"UA-9909000-1"
            sb.AppendLine("pageTracker._trackPageview();");
            sb.AppendLine("} catch(err) {}<//script>");
            sb.AppendLine();
            return sb.ToString();
        }
    }

This is what i got
