我需要以表格形式显示某些数据,并且更喜欢使用多遍 xslt使用node-set()以便我可以避免部署其他工具(如xsltproc)。 现在,我能够分两步完成所需的任务,即
步骤1:使用身份模板将XML-1转换为XMl-2(xsl:copy,使用xsl:element到 添加动态元素'dev'和'qa`):
<projectteam>
<member>
<name>John</name>
<role>dev</role>
<hrs>100</hrs>
</member>
<member>
<name>Peter</name>
<role>qa</role>
<hrs>80</hrs>
</member>
</projectteam>
要
<projectteam>
<member>
<name>John</name>
<dev>100</dev>
</member>
<member>
<name>Peter</name>
<qa>80</qa>
</member>
<projectteam>
然后,使用另一个XSLT-FO样式表将XML#2转换为具有所需布局的PDF文档:
name | dev | qa | ----------------- John | 100 | | Peter| | 80 | ----------------- Total| 100 | 80 |
我尝试使用node-set()
(我猜错了)将这两个步骤结合起来,但是
我得到的结果如下:
name | dev | qa | ----------------- Total| 0 | 0 |
样式表-1:将XML-1转换为XML-2,导入另一个样式表'projDisplay.xsl', 使用node-set()来调用导入的样式表,但数据没有显示?
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:exslt="http://exslt.org/common"
>
<!-- import stylesheet to display XML-2 in tabular form -->
<xsl:import href="projDisplay.xsl"/>
<xsl:template match="/">
<fo:root>
<xsl:apply-templates/>
</fo:root>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:variable name="newXmlData">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:variable>
<!-- ==> This is where my problem is - it goes to the template defined in -->
<!-- projDisplay.xsl (xslt-fo, pretty big one with page layout etc. hence -->
<!-- not included here, but it works on its own though) as I can see the -->
<!-- table header, and an empty totals row, but non of the rows are displayed -->
<xsl:apply-templates
select="exslt:node-set($newXmlData)/projectteam" mode="display"
/>
</xsl:template>
<!-- replace element 'role' with a new element - role name (i.e. dev or qa) -->
<!-- and set its value as 'hrs -->
<xsl:template match="role">
<xsl:element name="{.}"> <xsl:value-of select="../hrs"/> </xsl:element>
</xsl:template>
<!-- eliminate element 'hrs' -->
<xsl:template match="hrs"/>
</xsl:stylesheet>
样式表中的注释部分对我来说不合适。有什么建议 关于如何纠正它?
谢谢!

这是有效的解决方案。它基于Tomalak的原始解决方案,有一些小问题 修改(如模式标志等)再次,感谢Tomalak !!

怎么样:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:exslt="http://exslt.org/common"
exclude-result-prefixes="exslt"
>
<xsl:import href="projDisplay.xsl"/>
<xsl:template match="/">
<!-- store intermediary format as a RTF -->
<xsl:variable name="newXmlData">
<xsl:apply-templates />
</xsl:variable>
<!-- now we can the apply imported rules -->
<xsl:apply-templates
select="exslt:node-set($newXmlData)/projectteam"
mode="import"
/>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="member/role">
<xsl:element name="{.}">
<xsl:value-of select="../hrs" />
</xsl:element>
</xsl:template>
<xsl:template match="member/*" />
<xsl:template match="projectteam" mode="import">
<fo:root>
<xsl:apply-imports />
</fo:root>
</xsl:template>
</xsl:stylesheet>
