我正在使用 xslt 1.0 版将 XML 文件转换为发送给第三方的文本文件。第三方格式要求数据字段用 0x1F（ascii 单位分隔符）分隔，组用 0x1D（ascii 组分隔符）分隔，记录用 0x1E（ascii 记录分隔符）分隔。在样式表中使用这些会导致以下错误。
字符 ' '，十六进制值 0x1D 在 XML 文档中是非法的。
我目前正在使用扩展字符集中的 0x80 到 0x82，然后通过 c# 中的替换函数运行转换结果，将我使用的值替换为我实际需要的值，但似乎应该有更好、更有效的方法去做这个。
有没有办法直接使用样式表将这些值输出到文本文件？

更新
对于那些可能正在寻找类似解决方案的人，我最终在样式表中使用了 C# 脚本。
<msxsl:script implements-prefix="CSharpScripts" language="C#">
public string FS()
{
return '\u001F'.ToString();
}
public string GS()
{
return '\u001D'.ToString();
}
</msxsl:script>
然后可以像这样使用它：
<xsl:value-of select="CSharpScripts:FS()"/>
您确实需要在加载XslCompiledTransform时使用XsltSettings设置EnableScript = true ，并在用于输出的XmlWriter上设置CheckCharacters = false ：
var xslt = new XslCompiledTransform();
xslt.Load(
@"E:\TFS\Transforms\TestTransform.xslt",
new XsltSettings() {EnableScript = true}, null);
var writerSettings = xslt.OutputSettings.Clone();
writerSettings.CheckCharacters = false;
var sb = new StringBuilder();
var xmlOutput = XmlWriter.Create(sb, writerSettings);
xslt.Transform(@"E:\samples.xml", xmlOutput);
感谢@Abel 为我指明了正确的方向。
