我是XSL的新手,我正尝试使用XSLT将XML的一个节点复制到同一XML中的另一个节点。我可以按预期方式转换文件,但是XMLNS属性已添加到不需要的目标位置。
我已经使用XSLT2.0尝试了所有copy-namespaces ='no'选项,但是那不起作用。另外,我不能在XSLT中使用名称空间的前缀,并使用排除名称空间来避免xmlns,因为传入的XML文件是动态的并且名称空间不断变化。我不能在XSLT中将所有名称空间都声明为前缀。
传入XML:

答案 0 :(得分:0)
您在问错问题。您不想“删除名称空间”-您想要更改已转换元素的名称空间。这类似于重命名元素。
现在,由于您的示例令人困惑(且时间太长),请考虑以下事项:
XML
<root>
<colors>
<color>red</color>
<color>blue</color>
</colors>
<shapes xmlns="some-unknown-namespace">
<shape>circle</shape>
<shape>square</shape>
</shapes>
<sizes>
<size>small</size>
<size>large</size>
</sizes>
</root>
要将shapes
(及其继承者的继承人)的名称空间更改为无名称空间,而无需事先知道原始名称空间将是什么,可以执行以下操作:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[ancestor-or-self::*[name()='shapes']]">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="@*|node()"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
结果
<?xml version="1.0" encoding="UTF-8"?>
<root>
<colors>
<color>red</color>
<color>blue</color>
</colors>
<shapes>
<shape>circle</shape>
<shape>square</shape>
</shapes>
<sizes>
<size>small</size>
<size>large</size>
</sizes>
</root>
让修改代码以将形状移动到尺寸并删除形状节点。
好的,我们这样做:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="sizes">
<xsl:copy>
<xsl:apply-templates/>
<!-- move the shapes into sizes -->
<xsl:apply-templates select="../*[name()='shapes']/*"/>
</xsl:copy>
</xsl:template>
<!-- remove the shapes element -->
<xsl:template match="*[name()='shapes']"/>
<xsl:template match="*[ancestor::*[name()='shapes']]">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="@*|node()"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
结果
<?xml version="1.0" encoding="UTF-8"?>
<root>
<colors>
<color>red</color>
<color>blue</color>
</colors>
<sizes>
<size>small</size>
<size>large</size>
<shape>circle</shape>
<shape>square</shape>
</sizes>
</root>
