本文介绍了具有动态路径的XSLT文档的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有XSLT 1.0标准.我有一个来自服务器的动态XML，它非常简单，而第二个XML作为配置.基于第一个(动态的)，我必须从第二个中获取适当的节点信息.这是第一个文件:

I have XSLT 1.0 standard.I have one dynamic XML from server which is quite simple and second XML as configuration. Base on first one (which is dynamic) I have to pick up proper nodes information from second one.This is first document:

<?xml version="1.0" encoding="UTF-8" ?>
<response>
    <response>SUCCESS</response>
    <responsedata>
        <hit>
            <url>http://domain.com/page.html</url>
            <id>2437</id>
            <title>Page title</title>
            <language>en</language>
            ...
            ...
        </hit>
    </responsedata>
</response>

第二个配置XML用于页脚，页眉按语言划分.像这样的东西:

Second configuration XML is for footer, header divided by languages. Something like that:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <set id="local">
        <header>
            <en>
                <![CDATA[
<div id="header">
    <p>English code</p>
</div>
                ]]>
            </en>
            <fr>
                <![CDATA[
<div id="header">
    <p>French code</p>
</div>
                ]]>
            </fr>
        </header>
    </set>
</config>

我需要从第二个XML中提取适当的语言相关代码.我尝试了以下代码，但它不起作用:

I need pick up proper language depended code from second XML.I tried following code and it doesn't work:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" omit-xml-declaration="yes" encoding="utf-8" indent="yes" doctype-system="about:legacy-compat" />
    <xsl:variable name="configuration" select="document('settings.xml')/config/set[@id='local']" />
    <xsl:variable name="lang" select="response/responsedata/hit/language" />

    <xsl:template name="getvalueofnode">
        <xsl:param name="path" />
        <xsl:param name="context" select="$configuration" />
        <xsl:choose>
            <xsl:when test="contains($path,'/')">
                <xsl:call-template name="getvalueofnode">
                    <xsl:with-param name="path"
                        select="substring-after($path,'/')" />
                    <xsl:with-param name="context"
                        select="$context/*[name()=substring-before($path,'/')]" />
                </xsl:call-template>
            </xsl:when>
            <xsl:otherwise>
                <p>value: <xsl:value-of select="$context/*[name()=$path]" disable-output-escaping="yes" /></p>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>

    <xsl:template match="/">
        <xsl:element name="html">
            <xsl:attribute name="lang"><xsl:value-of select="$lang" /></xsl:attribute>
            <xsl:element name="head">
                <xsl:attribute name="lang"><xsl:value-of select="$lang" /></xsl:attribute>
            </xsl:element>
            <xsl:element name="body">
                <xsl:attribute name="lang"><xsl:value-of select="$lang" /></xsl:attribute>
                <p>lang: <xsl:value-of select="$lang" /></p>
                <p>
                <xsl:call-template name="getvalueofnode">
                    <xsl:with-param name="path" select="concat('/header/',$lang)" />
                </xsl:call-template>
                </p>
            </xsl:element>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

如果有人有任何建议或解决方案，那就太好了.

If some one has any suggestion or solution it will be fantastic.

推荐答案

由于您已经知道基于$lang的元素的名称，因此可以一起消除getvalueofnode模板.

Since you already know the name of the element based on $lang, you can eliminate the getvalueofnode template all together.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html" omit-xml-declaration="yes" encoding="utf-8" indent="yes" doctype-system="about:legacy-compat" />
  <xsl:variable name="configuration" select="document('settings.xml')/config/set[@id='local']" />
  <xsl:variable name="lang" select="response/responsedata/hit/language" />

  <xsl:template match="/">
    <html lang="{$lang}">
      <head lang="{$lang}"/>
      <body lang="{$lang}">
        <p>lang: <xsl:value-of select="$lang" /></p>
        <p>value: <xsl:value-of disable-output-escaping="yes" select="$configuration/header/*[name()=$lang]"/></p>
      </body>
    </html>
  </xsl:template>

</xsl:stylesheet>

我也摆脱了所有的xsl:element和xsl:attribute.通常可以通过直接编码元素并使用 AVT(属性值模板).

I also got rid of all the xsl:element and xsl:attribute. These can normally be avoided by coding the elements directly and using AVT (attribute value templates) for the attributes.

上面的样式表使用您的XML输入文件(经过Saxon 6.5.5和Saxon-HE 9.3.0.5测试)产生以下输出:

The stylesheet above produces the following output using your XML input files (tested with Saxon 6.5.5 and Saxon-HE 9.3.0.5):

<!DOCTYPE html
  SYSTEM "about:legacy-compat">
<html lang="en">
   <head lang="en">
      <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
   </head>
   <body lang="en">
      <p>lang: en</p>
      <p>value:

         <div id="header">
         <p>English code</p>
         </div>


      </p>
   </body>
</html>
