我没有使用撒克逊语；我正在使用直接的 XSLT 1.0。
我正在使用以下 XSLT 文档：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:fo="http://www.w3.org/1999/XSL/Format"
                xmlns:a="http://schemas.datacontract.org/2004/07/Delek.Store"
                xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                xmlns:user="urn:my-scripts">

  <msxsl:script implements-prefix='user' language='CSharp'>
    <![CDATA[  
    
      public string ConvertUTCtoLocal(DateTime EndTime)
      {
        var Local = EndTime.ToLocalTime().ToString("MM/dd/yyyy") + " " + EndTime.ToLocalTime().ToString("HH:mm:ss");
        return Local;
      }
    
    ]]>
  </msxsl:script>

  <!-- .. since we have a source default namespace we have to declare a namespace here   exclude-result-prefixes="msxsl" -->
  <xsl:output method="xml" indent="yes"/>
  <xsl:param name="header" />
  <xsl:param name="footer"/>
  <xsl:param name="ReceiptLayoutCodeType"/>
  <xsl:variable name="spaces27" select="'                           '"/>
  <xsl:template match="/">
    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
      <s:Body>
        <epos-print xmlns="http://www.epson-pos.com/schemas/2011/03/epos-print">
          <xsl:apply-templates select ="Sale"/>
          <feed unit="24"/>
          <cut/>
        </epos-print>
      </s:Body>
    </s:Envelope>
  </xsl:template>
  <xsl:template match="Sale">
    <text lang="en" smooth="true" align="left" >
      Date<xsl:value-of select="concat(substring($spaces27,9),user:ConvertUTCtoLocal(EndTime))"/>
    </text>

  </xsl:template>

</xsl:stylesheet>

当它尝试调用 C# 脚本时，出现错误

找不到名为 {urn:my-scripts}ConvertUTCtoLocal() 的匹配 1 参数函数

我所做的每次搜索都会返回撒克逊代码的错误。我没有使用撒克逊代码，我读到的所有内容都说格式与标准 W3C XSLT 中使用的格式不同。

有人对如何使此代码正常工作有任何建议吗？

真正奇怪的是，我正在检查https://www.freeformatter.com/xsl-transformer.html，对于我从网络上使用的任何示例代码，它都在说同样的事情。

那是我的代码吗？对 XML 1.0 的更新是否发生了什么？

我目前迷路了，可以使用一些帮助摆脱杂草。

人们可以用来测试的 XML 数据：

<Sale z:Id="i1" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/">

这是打印机返回的错误：

  <Success>Print Failed</Success> 
- <Res>
- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
- <soapenv:Body>
  <response success="false" code="SchemaError" status="0" battery="0" xmlns="http://www.epson-pos.com/schemas/2011/03/epos-print" /> 
  </soapenv:Body>
  </soapenv:Envelope>
  </Res>
  </Result>
