我试图编写一个XSLT来转换它，此时我有：

由于Azure创建源文档。我无法真正改变它，或者它是如何使用命名空间声明的。我的问题是在这一点上：
<Origin_Code>
<xsl:value-of select="/ins0:X12InterchangeXml/FunctionalGroup/TransactionSet/ns0:X12_00401_856/ns0:HLLoop1/ns0:N1Loop1/ns0:N1/N104/text()" />
</Origin_Code>
我没有得到价值。我的XPATH是错误的，或者我正在与使用ns0两次的Azure文档发生冲突，一次是
<ns0:ISA
xmlns:ns0="http://schemas.microsoft.com/Edi/X12ServiceSchema">
然后在同一份文件中：
<ns0:X12_00401_856
xmlns:ns0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006">
我不知道如何在伪XPATH中指示XPATH是什么
/ins0:X12InterchangeXml[@xmlns:ins0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006/InterchangeXML"]/FunctionalGroup[@DocType="http://schemas.microsoft.com/BizTalk/EDI/X12/2006#X12_00401_856"]/TransactionSet[@DocType="http://schemas.microsoft.com/BizTalk/EDI/X12/2006#X12_00401_856"]/ns0:X12_00401_856[@xmlns:ns0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006"]/ns0:HLLoop1[1]/ns0:N1Loop1/ns0:N1/N104/text()
同时还有XSLT支持基本上的XPATH：
/ins0:X12InterchangeXml[@xmlns:ins0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006/InterchangeXML"]/ns0:ISA[@xmlns:ns0="http://schemas.microsoft.com/Edi/X12ServiceSchema"]/ISA01/text()
答案 0 :(得分：2)
在样式表中，您可以使用您喜欢和需要的任何前缀，您不需要使用与输入XML相同的前缀，您只需要确保将前缀绑定到与您要选择输入元素。因此，如果您在输入中使用了具有不同命名空间URI的相同前缀，那么在您的XSLT中，使用绑定到第二个URI的不同前缀，并在XPath中使用该第二个前缀，例如， xmlns:ns0="http://schemas.microsoft.com/Edi/X12ServiceSchema" xmlns:ns2="http://schemas.microsoft.com/BizTalk/EDI/X12/2006"作为XSLT中的名称空间声明，然后在XPath表达式中使用这些前缀。
答案 1 :(得分：1)
您可以在XPath表达式中使用您喜欢的任何前缀，它不必与源文档中的前缀相同，只要它绑定到正确的命名空间即可。因此，源文档使用绑定到不同位置的不同命名空间的相同前缀应该不是问题。
