我通过c#把xml通过xsl转换为svg出问题。

[光明唧]

代码如下：
public string Convert()
{
FreeThreadedDOMDocument m_xmlDoc = new FreeThreadedDOMDocument();
FreeThreadedDOMDocument m_xslSheet = new FreeThreadedDOMDocument();
XSLTemplate m_xslTemplate = new XSLTemplateClass();
m_xmlDoc.async = false;
m_xslSheet.async = false;

if (m_XML != "")
{
m_xmlDoc.loadXML(m_XML);
}
else
{
return null;
}
if (m_XSL != "")
{
m_xslSheet.loadXML(m_XML);
}
else
{
return null;
}
m_xslTemplate.stylesheet=m_xslSheet;每次都是这里报错！郁闷
IXSLProcessor m_xslProcessor = m_xslTemplate.createProcessor();
m_xslProcessor.input = m_xmlDoc;
m_xslProcessor.transform();
m_SourceCode = (string)m_xslProcessor.output;
m_xmlDoc = null;
m_xslTemplate = null;
m_xslSheet = null;
m_xslProcessor = null;
return m_SourceCode;
}
有没有人帮我一把。
