Regex XSL转换失败，我可以'；我不明白为什么

作为编写XSL的新手，我在为当前项目调试XSL时遇到了问题。EditXXML只是因为错误而导致转换失败，但没有说明错误在哪里

有什么建议吗

源XML:

<soa:Label xmlns:soa="urn:telestream.net:soa:core" identifier="ac7af7e5-a536-40ae-b7ca-93e62009c86a" name="Duration - Timecode to Frames" description="" instance="dc07adf4-79e4-4d33-b740-ece5bc0af991" signature="00000000-0000-0000-0000-000000000000">
<soa:Parameter type="timecode" identifier="82795f2a-5a2e-41ca-b1da-0c35a9c584e4" bindable="True" name="Duration Timecode" enabled="true" disableable="false" optionseditable="false" row="-1" column="-1" columnspan="1">00:15:52:10@25
<soa:Default>00:00:00:00@29.97</soa:Default>
<soa:IsRequired>false</soa:IsRequired>
</soa:Parameter>

</soa:Parameter>
</soa:Label>

谢谢

如果您在测试XSLT，您将看到XSLT有两个错误

元素

xsl:analyze string

不允许是

xsl:stylesheet

您已在
这

xsl:analyze string

，但这意味着它仅在

xsl:matching子字符串

块，因此无法引用它 在哪里

有关具体细节，请参阅

您需要做的是移动

xsl:analyze字符串

，同时将

xsl:variable

声明的

total frames

包装在其周围，以便以后可以在模板中使用该变量

试试这个XSLT
