我们有以下格式不正确的输入XML，它们来自源系统。

<?xml version="1.0" encoding="UTF-8"?>
<ns0:invoiceOrder xmlns:ns0="http://cts.com"
               type="ABCD"

   </ns0:dates>
</ns0:invoiceOrder>

如果可以将以下标记添加到上述输入中，则可以使上述xml格式正确。

开始标签： 

<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
    <ns0:Message1>

相应的结束标记： 

    </ns0:Message1>
</ns0:Messages>

如何编写XSLT逻辑，以便生成以下输出？

    <?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
    <ns0:Message1>

我尝试了很多方法，但是由于输入的XML格式不正确，因此在生成上述输出时遇到了问题。

您可以使用XPath 3 parse-xml-fragment函数在Saxon 9.8或9.9或Altova 2017/2018/2019支持的XSLT 3中执行此操作，例如，可以将您拥有的片段作为字符串参数传递： 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="#all"
    version="3.0">

    <xsl:param name="fragment-string" as="xs:string"><![CDATA[<?xml version="1.0" encoding="UTF-8"?>
<ns0:invoiceOrder xmlns:ns0="http://cts.com"

    </xsl:template>

</xsl:stylesheet>

https://xsltfiddle.liberty-development.net/bFDb2Dd

当然，在XSLT 2/3中，您还可以使用unparsed-text例如用片段加载另一个文档。

<xsl:param name="fragment-uri" as="xs:string">fragment.xml</xsl:param>

<xsl:param name="fragment-string" as="xs:string" select="unparsed-text($fragment-uri)"/>

示例https://xsltfiddle.liberty-development.net/bFDb2Dd/1。

在支持外部实体的XML级别上，您可以使用包含所需包装元素的文档，这些元素包括将片段作为外部实体，例如在http://xsltransform.hikmatu.com/jyH9rLR或https://xsltfiddle.liberty-development.net/eiZQaGf上，您可以声明包装文件
