条件 <xsl:output>在 XSLT 1.0 中? [英] Condition <xsl:output> in XSLT 1.0?

问题描述

我有一个 XSLT 1.0(2.0 不是一个选项)样式表，它产生XHTML.它可以根据参数生成完整的 XHTML有效的文档或只是一个

...

片段，用于包含在网页中.

我的问题是在这两个中产生不同的 XML 声明案件.对于独立页面，我需要:

<xsl:output doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"/>

对于

之一:

但是 不能包含在 中.它只能是 的 直接 子级.

我看到的唯一解决方案是使用大多数模板创建一个样式表，然后使用正确的 <xsl:output> 和两个小的包装器"创建 <xsl:import> 主样式表.

我一直在寻找更好的主意，但显然没有.根据 Andrew Hare 和 jelovirt 的建议，我编写了两个驱动程序"，两个简单的样式表，它们分别调用了正确的 和主样式表.这是这些驱动程序之一，用于独立 HTML 的驱动程序:

<xsl:import href="traceroute2html.xsl"/><xsl:param name="standalone" select="'true'"/><xsl:output doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"/></xsl:stylesheet>

解决方案

听起来您需要的是两个不同的样式表.如果可能，您应该创建两个单独的样式表并从代码中动态调用您需要的样式表.

I have an XSLT 1.0 (2.0 is not an option) stylesheet which produces XHTML. It can, depending on a parameter, produce a full XHTML validable document or just a <div>...</div> snippet, intended for inclusion in a Web page.

My problem is to produce different XML declarations in these two cases. For the standalone page, I need:

<xsl:output doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
       doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"/>

And for the <div> one:

<xsl:output omit-xml-declaration="yes"/>

But <xsl:output> cannot be included in an <xsl:if>. It can only be the direct child of <xsl:stylesheet>.

The only solution I see is to create a stylesheet with most of the templates and then two small "wrappers" with the right <xsl:output> and which will <xsl:import> the main stylesheet.

I was looking for a better idea but apparently there is none. Following advice from Andrew Hare and jelovirt, I wrote two "drivers", two simple stylesheets which call the proper <xsl:output> and then the main stylesheet. Here is one of these drivers, the one for standalone HTML:

<?xml version="1.0" encoding="us-ascii"?>
<!-- This file is intended to be used as the main stylesheet, it creates a 
 standalone Web page. 
-->
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

  <xsl:import href="traceroute2html.xsl"/>

  <xsl:param name="standalone" select="'true'"/>

  <xsl:output doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
      doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"/>

</xsl:stylesheet>

解决方案

It sounds like what you need is two different stylesheets. If at all possible you should create two separate stylesheets and dynamically call the one you need from code.
