我需要使用NewtonSoft Json.Net将JSON转换为XML。 JSON文件包含一些对象键中带冒号的数据。运行下面的代码时，会抛出异常。
XmlDocument xdoc = JsonConvert.DeserializeXmlNode(json, "root");
例外：The ':' character, hexadecimal value 0x3A, cannot be included in a name.
以下是JSON字符串中的一些示例键值对：
'jcr:type' : 'nt:file';
'jcr:content' ['jcr:uuid' : jfkjsaf]
这些只是从JSON字符串中随机挑选出来的;键和值都有冒号前缀。
如何让Json.Net忽略此异常并将JSON转换为XML？
好的，这是我的json文件

答案 0 :(得分：0)
您确定您的JSON格式正确吗？在修复了您提供的示例以正确格式化JSON之后，我使用最新版本的JSON.Net（5.0.8）尝试了以下代码。我没有看到任何将其转换为XML的异常。似乎Json.Net通过在转换期间从键中删除前缀来处理冒号。
class Program
{
static void Main(string[] args)
{
string json = @"
{
""jcr:type"" : ""nt:file"",
""jcr:content"" : [""jcr:uuid"", ""jfkjsaf""]
}";
XmlDocument xdoc = JsonConvert.DeserializeXmlNode(json, "root");
StringBuilder sb = new StringBuilder();
using (StringWriter sw = new StringWriter(sb))
using (XmlTextWriter writer = new XmlTextWriter(sw))
{
writer.Formatting = System.Xml.Formatting.Indented;
xdoc.WriteTo(writer);
}
Console.WriteLine(sb.ToString());
}
}
输出：
<root>
<type>nt:file</type>
<content>jcr:uuid</content>
<content>jfkjsaf</content>
</root>
要检查的事项：
JsonConvert.DeserializeXmlNode之前以任何方式操纵JSON字符串？如果是这样，你究竟在做什么？我们需要详细信息。如果这些问题不成问题，请编辑您的问题以提供您遇到问题的完整JSON，而不仅仅是点点滴滴。
现在您已经发布了完整的JSON，我可以看到问题。您的JSON中的密钥中包含多个冒号。以下是产生异常的最简单示例：
string json = @"{ "":jcr:data"": 54909 }";
XmlDocument xdoc = JsonConvert.DeserializeXmlNode(json, "root");
看起来有问题的密钥都是一样的 - :jcr:data。如果您可以控制JSON的源代码，那么最好的解决方案是修复源代码，使其在这些键的开头没有额外的冒号。
如果JSON来自您无法控制的第三方Web服务，一个简单的解决方法是在尝试将其转换为XML之前对JSON执行字符串替换。你可以这样做：
json = json.Replace(":jcr:data", "jcr:data");
我用你的完整JSON尝试了这个，它工作得很好。
