xslt - How to read a .properties file inside a .xsl file?

Question

I have an XSL file which uses a a static website link as shown below:

<xsl:template match="my_match">

    <xsl:variable name="variable1">
        <xsl:value-of select="sel1/Label = 'Variable1'"/>
    </xsl:variable>
    <xsl:copy-of select="sites:testPath('http://testsite.com/services/testService/v1.0', $fname, $lname,
     $email , $zip, $phone, $comments, $jps, boolean($myvar), string(cust/@custID), string(@paID))"/>
</xsl:template>

My question is that how to read a properties file(key value pair) in the xsl file. so in my properties file (e.g. site.properties) I have a key called site i.e. site=testsite.com/services/testService/v1.0

I want to use this site key in place of specifying url value in the xsl i.e. http://testsite.com/services/testService/v1.0. The reason for doing this is that this link changes depending on the various environments.

Is this possible? Please give your suggestions or a sample code if possible...Also if this is not possible...is there any work-around?

Answer 1

As a proof of concept:

Input .properties file:

# You are reading the ".properties" entry.
! The exclamation mark can also mark text as comments.
website = http://example.com
language = English
key with spaces = This is the value that could be looked up with the key "key with spaces".

Stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:f="Functions"
  version="2.0">

  <xsl:variable name="properties" select="unparsed-text('.properties')" as="xs:string"/>

  <xsl:template match="/" name="main">
    <xsl:value-of select="f:getProperty('language')"/>
  </xsl:template>

  <xsl:function name="f:getProperty" as="xs:string?">
    <xsl:param name="key" as="xs:string"/>
    <xsl:variable name="lines" as="xs:string*" select="
      for $x in 
        for $i in tokenize($properties, '
')[matches(., '^[^!#]')] return
          tokenize($i, '=')
        return translate(normalize-space($x), '', '')"/>
    <xsl:sequence select="$lines[index-of($lines, $key)+1]"/>
  </xsl:function>

</xsl:stylesheet>

The f:getProperty('language') will return 'English'.

See this as a proof of concept, this needs to be improved in many ways since it does not handle many of the different ways a .properties file can be authored.

I belive Alejandro or Dimitrie probably could improve this many times.
