示例 XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xslnsv="http://sample2.1">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="//xslnsv:Activity">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:if test="not(@IsForCompensation)
and (./xslnsv:IsForCompensationSpecified)">
<xsl:attribute name="IsForCompensation">
<xsl:value-of
select="./xslnsv:IsForCompensationSpecified" />
</xsl:attribute>
</xsl:if>
<xsl:apply-templates
select="@*|node()[local-name()
!= 'IsForCompensationSpecified']" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
这里我们有一个命名空间 xmlns:xslnsv="http://sample2.2" 当我们有一个具有相同命名空间的 xml 时它可以工作
<?xml version="1.0" encoding="utf-8"?>
<Package xmlns="http://sample2.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
<ElementAtLevel1>
<ElementAtLevel2 Id="cf9d2" Name="Pool 1">
<Activities>
<Activity Id="ef84125a">
<IsForCompensationSpecified
>false</IsForCompensationSpecified>
</Activity>
<Activity Id="39c5b8d8" Name="Task 1">
<IsForCompensationSpecified
>true</IsForCompensationSpecified>
</Activity>
</Activities>
</ElementAtLevel2>
</ElementAtLevel1>
<ExtendedAttributes />
</Package>
产生输出为:
<?xml version="1.0"?>
<Package xmlns="http://sample2.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ElementAtLevel1>
<ElementAtLevel2 Id="cf9d267d-e1ed-4616-adfb-d24d6844f775"
Name="Pool 1">
<Activities>
<Activity Id="ef84125a-0a01-4d76-9b3b-413ffb3c7a74"
IsForCompensation="false"/>
<Activity Id="39c5b8d8-9a72-40d1-b3e4-8cd973ccdf03"
Name="Task 1"
IsForCompensation="true"/>
</Activities>
</ElementAtLevel2>
</ElementAtLevel1>
<ExtendedAttributes/>
</Package>
但问题是:我们有一些具有不同命名空间的 xml,即http://sample2.1 具有不同命名空间的示例 xml
<?xml version="1.0"?>
<Package xmlns="http://sample2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ElementAtLevel1>
<ElementAtLevel2 Id="cf9d267d-e1ed-4616-adfb-d24d6844f775"
Name="Pool 1">
<Activities>
<Activity Id="ef84125a-0a01-4d76-9b3b-413ffb3c7a74"
IsForCompensation="false"/>
<Activity Id="39c5b8d8-9a72-40d1-b3e4-8cd973ccdf03"
Name="Task 1"
IsForCompensation="true"/>
</Activities>
</ElementAtLevel2>
</ElementAtLevel1>
<ExtendedAttributes/>
</Package>
那么我们没有正确的输出。
<?xml version="1.0" encoding="utf-8"?>
<Package xmlns="http://sample2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
<ElementAtLevel1>
<ElementAtLevel2 Id="cf9d2" Name="Pool 1">
<Activities>
<Activity Id="ef84125a">
<IsForCompensationSpecified
>false</IsForCompensationSpecified>
</Activity>
<Activity Id="39c5b8d8" Name="Task 1">
<IsForCompensationSpecified
>true</IsForCompensationSpecified>
</Activity>
</Activities>
</ElementAtLevel2>
</ElementAtLevel1>
<ExtendedAttributes />
</Package>
我修改了 xslt 以动态更改名称空间。带有新更改的示例 xslt
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xslnsv="http://sample2.2" >
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="vUrl" select="'http://sample2.2'"/>
<xsl:template match="*[namespace-uri()='http://sample2.1']">
<xsl:element name="{name()}" namespace="{$vUrl}">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="//xslnsv:Activity">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:if test="not(@IsForCompensation)
and (./xslnsv:IsForCompensationSpecified)">
<xsl:attribute name="IsForCompensation">
<xsl:value-of
select="./xslnsv:IsForCompensationSpecified" />
</xsl:attribute>
</xsl:if>
<xsl:apply-templates select="@*
|node()[local-name() != 'IsForCompensationSpecified']" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
在我看来,它能够更改命名空间,但在更改命名空间后无法选择元素。可能是指来自源 xml 的旧命名空间,即 2.1
但我仍然没有得到正确的输出;我得到以下输出。
<?xml version="1.0"?>
<Package xmlns="http://sample2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ElementAtLevel1>
<ElementAtLevel2 Id="cf9d2" Name="Pool 1">
<Activities>
<Activity Id="ef84125a">
<IsForCompensationSpecified>false</IsForCompensationSpecified>
</Activity>
<Activity Id="39c5b8d8" Name="Task 1">
<IsForCompensationSpecified>true</IsForCompensationSpecified>
</Activity>
</Activities>
</ElementAtLevel2>
</ElementAtLevel1>
<ExtendedAttributes/>
</Package>
