Include language files (as XML) on a XSLT
I doing the right transformations to develop a multilingual website. All the text of this website needs to be taken from an XML file because the output of the site will be the processed file.
This are the basic files, index.xml:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="xsl/index.xsl"?>
<page>
<entry>
<id>12</id>
<value>img/12.jpg</value>
</entry>
<entry>
<id>13</id>
<value>img/13.jpg</value>
</entry>
</page>
This entries are unique so they didn't need to be translated. My index.xsl:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- I'm including a language file, but I've various language files that will be 开发者_运维知识库stored in different folders -->
<xsl:param name="menu" select="document('../lang/index.xml')" />
<xsl:template match="/">
<html>
<xsl:attribute name="lang"><!-- name of the lang --></xsl:attribute>
<head></head>
<body>
<ul id="menu">
<xsl:for-each select="language/menu">
<li><xsl:value-of select="." /></li>
</xsl:for-each>
</ul>
<!-- this is not important, is an example -->
<xsl:for-each select="page/entry">
<xsl:value-of select="id" />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
I include ../lang/index.xml which contains all the words in some language, for example English. I need this site in 3 different languages that can be stored like:
/lang/en/index.xml
<language>
<menu>Home</menu>
<menu>Images</menu>
</language>
/lang/es/index.xml
<language>
<menu>Inicio</menu>
<menu>Imágenes</menu>
</language>
/lang/fr/index.xml
<language>
<menu>Maison</menu>
<menu>Images</menu>
</language>
My question is how I can manage this. I've no option to change that, because I'm not allowed to do a specific index.xsl file for each language.
Thank you in advance and sorry for school English.
This stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:param name="pLang" select="'es'"/>
<xsl:param name="pMenu"
select="document(concat('../lang/',$pLang,'/index.xml'),/)"/>
<xsl:template match="/">
<html lang="{$pLang}">
<head></head>
<body>
<ul id="menu">
<xsl:apply-templates select="$pMenu/*"/>
</ul>
<xsl:apply-templates select="page/entry"/>
</body>
</html>
</xsl:template>
<xsl:template match="language/menu">
<li>
<xsl:value-of select="." />
</li>
</xsl:template>
<xsl:template match="entry">
<img id="{id}" src="{value}"/>
</xsl:template>
</xsl:stylesheet>
Output:
<html lang="es">
<head></head>
<body>
<ul id="menu">
<li>Inicio</li>
<li>Imágenes</li>
</ul>
<img id="12" src="img/12.jpg" />
<img id="13" src="img/13.jpg" />
</body>
</html>
Language specific input file:
This file is to be transformed. In addition to the stylesheet processing instruction it also passes the actual language as a parameter to the stylesheet.
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="xsl/index.xsl"?>
<?xm-xsl-param name="lang" value="en"?>
<page>
<entry>
<id>11</id>
<value>bla </value>
</entry>
<entry>
<id>14</id>
<value>bla bla</value>
</entry>
</page>
Language independent file
This file gets included using the document function. Note that this does not need a stylesheet processing instruction:
<?xml version="1.0" encoding="UTF-8"?>
<page>
<entry>
<id>12</id>
<value>Lorem ipsum</value>
</entry>
<entry>
<id>13</id>
<value>Lorem ipsum</value>
</entry>
</page>
XSL transformation:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- the external parameter with a default value -->
<xsl:param name="lang" select="en" />
<xsl:variable name="entries"
select="page/entry | document('../lang/index.xml')/page/entry" />
<xsl:template match="/">
<html lang="{$lang}">
<head></head>
<body>
<!-- accessing an entry by its id value -->
<xsl:value-of select="$entries[id = 12]/value"/>
<!-- looping all entries -->
<xsl:for-each select="$entries">
<xsl:sort select="id" order="ascending"/>
<xsl:value-of select="id" />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
