我的第一篇文章。在开始之前，我会承认我已经破解了我的XSLT定义。而且我对命名空间没有很好的理解。
我正在使用XSLT转换XML。我需要一个默认命名空间出现在我的结果XML中。默认名称空间为：
的xmlns =＆＃34; HTTP：//www.bmecat.org/bmecat/2005fd"
没有此命名空间，我的转换工作正常。但是当我将它添加到我的XSLT时，我最终会出现一个空的xmlns =＆＃34;＆＃34;我的节点名称的属性。我已阅读了很多帖子，他们都告诉你在命名空间中添加前缀。但我无法添加一个。我需要将我的命名空间显示在xml中，如上所示。
这里是XSLT标题：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns="http://www.bmecat.org/bmecat/2005fd"
>
<!-- Format for output document -->
<xsl:output method="xml" indent="yes"/>
<!-- Find the ROOT element and data underneath it -->
<xsl:template match="ROOT">
<!-- BMEcat XML output -->
<BMECAT version="2005">
<!-- Header information -->
<HEADER>
<!-- Copy the BUYER nodes -->
<xsl:copy-of select="BUYER"/>
它为XML生成正确的标头。但是，它会影响具有空属性的节点名称：
<?xml version="1.0" encoding="utf-8"?>
<BMECAT version="2005"
xmlns="http://www.bmecat.org/bmecat/2005fd"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
>
<HEADER>
<BUYER xmlns="">
<BUYER_NAME>XYZ</BUYER_NAME>
</BUYER>
如何在不使用前缀的情况下将名称空间保留在xml输出头中，从而摆脱空的xmlns属性？
全部谢谢
这是完整的模板：

答案 0 :(得分：0)
你说你不想要
上的命名空间（联合国）声明<BUYER xmlns="">
这意味着，您希望结果文档中的BUYER元素位于名称空间http://www.bmecat.org/bmecat/2005fd中。但源文档中的BUYER元素没有名称空间。因此，结果文档中的BUYER元素与源文档中的BUYER元素不同：它不是精确副本，因此您无法使用<xsl:copy-of>生成它。复制元素永远不会更改元素的名称（命名空间是名称的重要部分）。
要更改源文档中元素的命名空间，您需要使用以下内容：
<xsl:template match="*" mode="rename">
<xsl:element name="{local-name()}" namespace="http://www.bmecat.org/bmecat/2005fd">
<xsl:copy-of select="@*"/>
<xsl:apply-templates mode="#current"/>
</xsl:element>
</xsl:template>
