处理编码元素

Question

我的xslt转换没有拿起我的文档，这是因为某些/大多数元素都是编码的，

e.g。我的文件：

<Template>
  <ID>14</ID>
  <Name>name of report</Name>
  <VersionNumber>1.0</VersionNumber>
  <CoverPage>
&lt;br /&gt;
&lt;br /&gt;
&lt;h3 style="text-align: center;"&gt;
&lt;br class="GENTICS_ephemera" /&gt;
&lt;/h3&gt;
&lt;h3 style="text-align: center;"&gt;
&lt;br class="GENTICS_ephemera" /&gt;
&lt;/h3&gt;
&lt;h3 style="text-align: center;"&gt;Property Valuation Report&lt;/h3&gt;  
  </CoverPage>
</Template>

这永远不会奏效：

  <xsl:template match="span">
    <fo:inline>
      <xsl:call-template name="tokenize-style"/>
      <xsl:apply-templates select="*|text()"/>
    </fo:inline>
  </xsl:template>
 <xsl:template match="br">
    <fo:block>
      <fo:leader />
    </fo:block>
  </xsl:template>

问题：如何以正确的格式获取我的文档（从技术上讲，我的xml是有效且格式正确的）但我想进行xsl转换，因此我需要能够获取正确的标记

以下是我的转换方法：

    private static MemoryStream Transform(XNode xmlData, XNode xslt)
    {
        XmlWriter writer = null;
        var xslTrans = new XslCompiledTransform();
        try
        {
            //load the xsl
            xslTrans.Load(xslt.CreateReader());

            //create the output stream
            var result = new MemoryStream();
            writer = XmlWriter.Create(result, null);

            //create the xml reader for the data
            var data = xmlData.CreateReader();

            //do the actual transform of xml
            xslTrans.Transform(data, null, writer);

            writer.Close();
            return new MemoryStream(result.ToArray());

        }
        catch (Exception e)
        {
            var errors = XslErrors.GetCompileErrors(xslTrans);
            if (errors == null)
            {
                // Failed to obtain list of compile errors
                throw;
            }

            if (writer != null) writer.Close();
            throw e;
        }
    }

Answer 1

以下是XslCompiledTransform和扩展对象的示例：

class Program
{
    static void Main(string[] args)
    {
        XslCompiledTransform proc = new XslCompiledTransform();
        proc.Load("../../XSLTFile1.xslt");

        XsltArgumentList xsltArgs = new XsltArgumentList();
        xsltArgs.AddExtensionObject("http://example.com/fp", new FragmentParser());

        proc.Transform("../../XMLFile1.xml", xsltArgs, Console.Out);
    }
}

public class FragmentParser
{
    public IXPathNavigable ParseFragment(string fragment)
    {
        XmlDocument doc = new XmlDocument();
        XmlDocumentFragment frag = doc.CreateDocumentFragment();
        frag.InnerXml = fragment;
        return frag;
    }
}

然后在样式表中，您可以使用以下代码：

<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:fp="http://example.com/fp"
  exclude-result-prefixes="fp"
>
  <xsl:template match="CoverPage">
    <Test>
      <xsl:apply-templates select="fp:ParseFragment(.)/node()"/>
    </Test>
  </xsl:template>

  <xsl:template match="h3">
    <heading>
      <xsl:apply-templates/>
    </heading>
  </xsl:template>
</xsl:stylesheet>

[编辑] 在样式表中，您可以更改

  <fo:page-sequence master-reference="Cover">
    <fo:flow flow-name="xsl-region-body" >
      <fo:block id="CoverPageWrapper">
        <xsl:apply-templates select="fp:ParseFragment(.)/node()"/>
        <xsl:apply-templates select="CoverPage" />
      </fo:block>
    </fo:flow>
  </fo:page-sequence>

到

  <fo:page-sequence master-reference="Cover">
    <fo:flow flow-name="xsl-region-body" >
      <fo:block id="CoverPageWrapper">
        <xsl:apply-templates select="fp:ParseFragment(CoverPage)/node()"/>
      </fo:block>
    </fo:flow>
  </fo:page-sequence>

或为CoverPage添加模板，例如

<xsl:template match="CoverPage">
  <xsl:apply-templates select="fp:ParseFragment(.)/node()"/>
</xsl:template>

然后在上面你就可以做到这一点。

  <fo:page-sequence master-reference="Cover">
    <fo:flow flow-name="xsl-region-body" >
      <fo:block id="CoverPageWrapper">
        <xsl:apply-templates select="CoverPage" />
      </fo:block>
    </fo:flow>
  </fo:page-sequence>
