使用 Web 服务保存共享点自定义 Web 部件时格式正确的 XML 错误

【中文标题】使用 Web 服务保存共享点自定义 Web 部件时格式正确的 XML 错误

【英文标题】：Well-formed XML error when saving the sharepoint custom web part using web services

【发布时间】：2012-02-12 00:31:48

【问题描述】：

我创建了一个具有自定义集合属性（选项卡）的自定义 Web 部件。当您在编辑模式下（通过浏览器）编辑和保存自定义属性时，Web 部件可以正常工作。我想使用 Web 服务更新我的自定义 Web 部件，所以我导出了 Web 部件并获取了 xml 内容并按原样传递（这样我就可以轻松地对其进行测试），但是发生了错误

The file you imported is not valid. 
Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML.

我已经使用在线 xml 验证器验证了 xml 并删除了此语句

<?xml version="1.0" encoding="utf-16"?>

因为根据 XML 验证器，这是导致 XML 格式不正确的原因，但仍然没有运气，发生了同样的错误。

有什么想法吗？我无法弄清楚 Tabs 属性上的 XML 有什么问题。

代码：

    string webPartXml = string.Empty;
    string pageUrl = currenturl;

        Guid storageKey = new Guid(webpartid);

        using (StreamReader sr = new StreamReader(@"C:\tab.txt"))
                    
            webPartXml = sr.ReadToEnd();                
        
        webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">");

        try
        
            svc.SaveWebPart2(pageUrl, storageKey, webPartXml, WebpartpagesSvc.Storage.Shared, false);
        catch(Exception err)
        
            throw;
        

Tab.txt (Tab.webpart)

错误信息

base System.SystemException = "Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown."
InnerText = "The file you imported is not valid. Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML."
InnerXml = "<errorstring xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\">The file you imported is not valid. Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML.</errorstring>"

【参考方案1】：

我认为当您尝试将 xml 恢复为原始文件时会破坏它。你真的需要这行代码吗：

webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 

如果你删除它会发生什么？ 如果它不起作用，我建议将值包装在 CDATA-tag 中以转义 xml：

string startTabProperty = @"<property name=""Tabs"" type=""Test.Tabs, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c9e6068352095bx6"">";
string endTabProperty = "></property>"; //Note the >< in order to identify correct place
webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 
webPartXml = webPartXml.Replace(startTabProperty, startTabProperty + "<![CDATA[");
webPartXml = webPartXml.Replace(endTabProperty , ">" + "]]>" + "</property>");

祝你好运！

【参考方案2】：

在模块的Element.xml 中写入下面的代码，并在listUrl 和TitleUrl 中仅更改您的列表名称

<Module>
<File>
<AllUsersWebPart WebPartZoneID="wzMain" WebPartOrder="2">
    <![CDATA[
    <webParts>
    <webPart xmlns="http://schemas.microsoft.com/WebPart/v3">

    <importErrorMessage>Cannot import this Web Part.</importErrorMessage>
    </metaData>
    <data>
    <properties>
    <property name="ShowWithSampleData" type="bool">False</property>
