进行服务器端XML处理时出错

本文关键字：出错 处理 XML 服务器端 | 更新日期: 2023-09-27 18:21:22

所以我有一个aspx页面，它将XML+XSL服务器到客户端，并进行客户端转换，效果很好。

我正在尝试检测客户端，如果他们不支持客户端转换，我将在服务器端进行。我正在中断呈现处理器将返回XML的aspx页面，并获取它的输出，将其与XSL页面的输出组合并提供给它。然而，这种输出形式并不完善。我得到

XML Parsing Error: mismatched tag. Expected: </link>.
Location: http://oohrl.com/dashboard.aspx
Line Number 36, Column 20:        </script></head>
-------------------^

在客户端生成的输出中，它运行良好，例如，我得到

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <link rel="stylesheet" type="text/css" href="./css/dboard.css"/>

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js"/>
    <script type="text/javascript">
                $(document).ready(function () {
                    $("#BlogSelectList li a").live("click", function () {
                        var str = ($(this).attr("href")).slice(1, 37)
                        $.ajax({
                            contentType: "application/json; charset=utf-8",
                            url: '../ws/WebServices.asmx/SetActiveBlog',
                            data: '{ActiveBlogID: "' + str + '"}',
                            dataType: 'json',
                            type: "post",
                            success: function (j) {
                                    window.location.href = 'dashboard.aspx'
                            }
                        });
                    });
                })
        function showlayer(layer) {
            var myLayer = document.getElementById(layer);
            if (myLayer.style.display == "none" || myLayer.style.display == "") {
                myLayer.style.display = "block";
                }
                else {
            myLayer.style.display = "none";
            }
        }
        </script></head>

如果我在服务器端生成它，我会得到

                            var str = ($(this).attr("href")).slice(1, 37)
                            $.ajax({
                                contentType: "application/json; charset=utf-8",
                                url: '../ws/WebServices.asmx/SetActiveBlog',
                                data: '{ActiveBlogID: "' + str + '"}',
                                dataType: 'json',
                                type: "post",
                                success: function (j) {
                                        window.location.href = 'dashboard.aspx'
                                }
                            });
                        });
                    })
                        function showlayer(layer) {
                            var myLayer = document.getElementById(layer);
                            if (myLayer.style.display == "none" || myLayer.style.display == "") {
                                myLayer.style.display = "block";
                            }
                            else {
                                myLayer.style.display = "none";
                            }
                        }

        </script></head>

这给了我错误。当然，我注意到<link/>和<link>标记的差异，但我不知道为什么服务器端处理引擎会给我不同的结果，也不知道如何修复它？

以下是我用来在服务器上生成XHTML的代码

    protected override void Render(HtmlTextWriter writer)
    {
        StringBuilder sb = new StringBuilder();
        StringWriter sw = new StringWriter(sb);
        HtmlTextWriter hWriter = new HtmlTextWriter(sw);
        base.Render(hWriter);
        // *** store to a string
        string XMLOutput = sb.ToString();
        // *** Write it back to the server
        if (!Request.Browser.IsBrowser("IE"))
        {
            writer.Write(XMLOutput);
        }
        else
        {
            StringWriter XSLsw = new StringWriter();
            HttpContext.Current.Server.Execute("DashboardXSL.aspx", XSLsw);
            string output = String.Empty;
            using (StringReader srt = new StringReader(XSLsw.ToString())) // xslInput is a string that contains xsl
            using (StringReader sri = new StringReader(XMLOutput)) // xmlInput is a string that contains xml
            {
                using (XmlReader xrt = XmlReader.Create(srt))
                using (XmlReader xri = XmlReader.Create(sri))
                {
                    XslCompiledTransform xslt = new XslCompiledTransform();
                    xslt.Load(xrt);
                    using (StringWriter _sw = new StringWriter())
                    using (XmlWriter xwo = XmlWriter.Create(_sw, xslt.OutputSettings)) // use OutputSettings of xsl, so it can be output as HTML
                    {
                        xslt.Transform(xri, xwo);
                        output = _sw.ToString();
                    }
                }
            }
            writer.Write(output);
            Response.Flush();
            Response.End();
       }

进行服务器端XML处理时出错

因为输出文档的根元素是<html>，所以处理程序选择HTML作为默认格式。要创建格式良好的XHTML文档，请确保XSLT包含以下内容作为根<xsl:stylesheet>或<xsl:transform>元素的子元素：

<xsl:output method="xml" omit-xml-declaration="yes" />

我不得不将xsl表上的内容类型设置为text/html，这解决了所有问题。

请注意，此更改仅在转换服务器端时使用。当将其发送到客户端进行客户端转换时，它不会更改为text/html/
