vb.net - xslt.Load(新 XmlTextReader(新 StringReader(xslt))) "xslt compile error"

Question

我已经阅读了其他帖子，但它们没有解决我的问题。环境为VB 2008(2.0 Framework)下面的代码在 xslt.Load 行导致 XSLT 编译错误下面是错误的输出。我将 XSLT 作为字符串传递，所以不确定为什么会收到错误消息。

Public Function xFrmTlogs(ByVal sXLST As String, ByVal sXML As String) As String
    Dim xslt As New XslCompiledTransform()
    Dim HTMLoutput As String
    Dim writer As New StringWriter()

    Try
        xslt.Load(New XmlTextReader(New StringReader(sXLST.ToString)))
    Catch ex As Exception
        xFrmTlogs = ex.ToString
    End Try

    Dim sourceReader As System.Xml.XmlReader = System.Xml.XmlReader.Create(New System.IO.StringReader(sXML))

    Try
        xslt.Transform(sourceReader, Nothing, writer)
    Catch ex As Exception
        xFrmTlogs = ex.ToString
    End Try

    HTMLoutput = writer.ToString()
    writer.Close()
    xFrmTlogs = HTMLoutput
End Function

存储在 sXSLT 中的 XSLT 脚本可能包含 <xsl:include>或 <xsl:import>试图包含/导入位于 H:\Program Files\common\tr_period.xsl 的另一个 XSLT 脚本文件的元素.由于该文件不存在或无法访问，因此转换失败。
