XSLT - 在应用其他模板之前更新原始 xml 的命名空间
XSLT - Update namespaces of the original xml before applying other templates
我有一个 xml 如下：
<?xml version="1.0" encoding="UTF-8"?>
<mdb:MD_Metadata xmlns:mdb="http://standards.iso.org/iso/19115/-3/mdb/1.0"
xmlns:cit="http://standards.iso.org/iso/19115/-3/cit/1.0"
xmlns:lan="http://standards.iso.org/iso/19115/-3/lan/1.0"
xmlns:mcc="http://standards.iso.org/iso/19115/-3/mcc/1.0"
xmlns:gco="http://standards.iso.org/iso/19115/-3/gco/1.0">
<mdb:metadataIdentifier>
<mcc:MD_Identifier>
<mcc:authority>
<cit:CI_Citation>
<cit:title>
<gco:CharacterString>Old UUID</gco:CharacterString>
</cit:title>
</cit:CI_Citation>
</mcc:authority>
<mcc:code>
<gco:CharacterString>3796749d-c8a5-46ae-af11-24a977cb1d9a</gco:CharacterString>
</mcc:code>
<mcc:codeSpace>
<gco:CharacterString>urn:uuid</gco:CharacterString>
</mcc:codeSpace>
</mcc:MD_Identifier>
</mdb:metadataIdentifier>
</mdb:MD_Metadata>
我想在应用其他模板之前更新名称空间（mdb 和 cit to2.0）：

只有当原始文件中与 mdb 和 cit 关联的命名空间如下所示时，上面的样式表才有效：

我如何才能先更新命名空间，然后再根据更新的 xml 应用其余模板？
