C#如何在内存对象中执行实时xslt转换？

Question

我有一个带有2个参数的函数:1 = XML文件,2 = XSLT文件,然后执行转换并返回生成的HTML.

这是功能:

/// <summary>
/// Will apply an XSLT style to any XML file and return the rendered HTML.
/// </summary>
/// <param name="xmlFileName">
/// The file name of the XML document.
/// </param>
/// <param name="xslFileName">
/// The file name of the XSL document.
/// </param>
/// <returns>
/// The rendered HTML.
/// </returns>
public string TransformXml(string xmlFileName, string xslFileName)
{
    var xtr = new XmlTextReader(xmlFileName)
                  {
                      WhitespaceHandling = WhitespaceHandling.None
                  };
    var xd = new XmlDocument();
    xd.Load(xtr);

    var xslt = new System.Xml.Xsl.XslCompiledTransform();
    xslt.Load(xslFileName);
    var stm = new MemoryStream();
    xslt.Transform(xd, null, stm);
    stm.Position = 1;
    var sr = new StreamReader(stm);
    xtr.Close();
    return sr.ReadToEnd();
}

我想更改函数不接受XML的文件,而只是一个对象.该对象与xslt完全兼容,如果它被序列化为文件.但我不想首先将它序列化为文件.

所以回顾一下:保持xslt来自文件,但xml输入应该是我传递的对象,并且希望在没有任何文件系统交互的情况下生成xml.

您可以将对象序列化为字符串,将字符串加载到a中XmlDocument,然后执行转换:

public string TransformXml(object data, string xslFileName)
{

    XmlSerializer xs = new XmlSerializer(data.GetType());
    string xmlString;
    using (StringWriter swr = new StringWriter())
    {
        xs.Serialize(swr, data);
        xmlString = swr.ToString();
    }

    var xd = new XmlDocument();
    xd.LoadXml(xmlString);

    var xslt = new System.Xml.Xsl.XslCompiledTransform();
    xslt.Load(xslFileName);
    var stm = new MemoryStream();
    xslt.Transform(xd, null, stm);
    stm.Position = 0;
    var sr = new StreamReader(stm);
    return sr.ReadToEnd();
}
