创建XMLTextReader，但XslCompiledTransform.Transform失败，字符无效 [英] XMLTextReader is created but XslCompiledTransform.Transform fails with invalid character

问题描述

我的代码:

using (XmlTextReader inputReader = new XmlTextReader(xml, XmlNodeType.Document, new XmlParserContext(null, null, "en", XmlSpace.Default)))
        {
            XsltArgumentList arglist = new XsltArgumentList();
            GetXSLT().Transform(inputReader, arglist, outputStream);
        }

XmlTextReader 创建良好，在XML内有一个用于垂直制表符(& #xB; )

The XmlTextReader is created fine, inside the XML there is an entity reference for a vertical tab ()

出错的行是对Transform的调用.它说有一个无效的XML字符(当然是垂直标签).

The line that errors is the call to Transform. It says that there is an invalid XML character (the vertical tab of course).

我尝试使用以下文章中引用的方法:
在C#中转义无效的XML字符

I've tried using the approach referenced in the following article:
Escape invalid XML characters in C#

我的问题是:如何使用.NET框架(如链接状态)删除或忽略无效字符?

My question is: how can I remove or ignore the invalid characters using the .NET framework like the link states?

注意:无需硬编码要替换的实体引用列表(我已经在这样做了，这太可怕了，我感到很不舒服，我应该这样做)

note: in a way that doesn't involve hard coding a list of entity references to replace (I'm already doing this and it is horrible and I feel bad, and I should)

推荐答案

尝试在读写时忽略无效的XML字符:

Try ignoring invalid XML characters both while reading and writing:

var readerSettings = new XmlReaderSettings() { CheckCharacters = false, ConformanceLevel = ConformanceLevel.Document };

using (var inputReader = XmlTextReader.Create(xml, readerSettings, new XmlParserContext(null, null, "en", XmlSpace.Default)))
{
    XsltArgumentList arglist = new XsltArgumentList();
    var xslt = GetXSLT();

    var writerSettings = xslt.OutputSettings.Clone();
    writerSettings.CheckCharacters = false;

    using (var outputWriter = XmlWriter.Create(outputStream, writerSettings))
    {
        xslt.Transform(inputReader, arglist, outputWriter);
    }
}
