XLT格式化XML那点事(二)

接上篇《XML通过XSL格式化的那点事(XML到自定义节点折叠显示)》，本文就如何将大的XLST分割成小文件和如何用C#将XML通过XSL生成HTML文件中的问题做下分析，避免有同样需求的朋友走弯路。

Import的使用

<xsl:Import> 元素必须在第一个节点

如何避免输出SelfClose的非法元素

简单繁琐的办法

<script type="text/javascript" src="nowhere.js">
<xsl:comment></xsl:comment>
</script>

一劳永逸的方法

不用XMLWriter使用自己定义的XMLHTMLWriter

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;

namespace XSLSelfClosing
{
    public class XmlHtmlWriter : XmlTextWriter
    {
        public XmlHtmlWriter(System.IO.Stream stream, Encoding en)
            : base(stream, en)
        {

            //Put all the elemnts for which you want self closing tags in this list.
            //Rest of the tags would be explicitely closed
            fullyClosedElements.AddRange(new string[] { "br", "hr" });
        }

        string openingElement = "";
        List<string> fullyClosedElements = new List<string>();

        public override void WriteEndElement()
        {
            if (fullyClosedElements.IndexOf(openingElement) < 0)
                WriteFullEndElement();
            else
                base.WriteEndElement();
        } 

        public override void WriteStartElement(string prefix, string localName, string ns)
        {
            base.WriteStartElement(prefix, localName, ns);
            openingElement = localName;
        }
    }
}
