XML - XSL to produce VoiceXML ---> One for Kevin Yank

**DLG_1** · Oct 26, 2001 12:00

anyone,

this is fairly simple (i think).

what I'm trying to do is a proof of concept...

I want to have a simple xml file that has employee info be "transformed" into a html file for the net and a voiceXML file for a phone system.
the html part is simple, got that (actually the book does,

however, the VoiceXML part has a small glitch that I'm having trouble with.

[H1]XML FILE[/H1]

Code:

<?xml version="1.0"?>
<employee FullSecurity="1">
	<name>John Doe</name>
	<department>Widget Sales</department>
	<phone>(555)555-5555<extension>2974</extension></phone>
	<salary>62,000</salary>
	<area>3</area>
</employee>

[H1]XSL 4 XML 2 HTML[/H1]

Code:

 <?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<head>
<title><xsl:value-of select="/employee/name"/></title>
</head>
<body>
<h1>Employee: <xsl:value-of select="/employee/name"/></h1>
<p>Department: <xsl:value-of select="/employee/department"/></p>
<xsl:if test="number(/employee/@FullSecurity)">
	<p>Salary: <xsl:value-of select="/employee/salary"/></p>
</xsl:if>
<p>Location: <xsl:apply-templates select="/employee/area"/></p>
</body>
</html>
</xsl:template>

<xsl:template match="phone">
	Phone: <xsl:value-of select="text()"/> x<xsl:value-of select="extension"/>
</xsl:template>

<xsl:template match="area">
	<xsl:choose>
		<xsl:when test=". = '1'">Toronto</xsl:when>
		<xsl:when test=". = '2'">London</xsl:when>
		<xsl:when test=". = '3'">New York</xsl:when>
		<xsl:when test=". = '4'">Tokyo</xsl:when>
		<xsl:otherwise>Unknown Location</xsl:otherwise>
	</xsl:choose>
</xsl:template>
</xsl:stylesheet>

[H1]XSL 4 XML 2 VOICEXML

Code:

 <?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/" disable-output-escaping="yes">
	&gt;!DOCTYPE vxml PUBLIC "-//BeVocal Inc//VoiceXML 2.0//EN"
	"http://cafe.bevocal.com/libraries/dtd/vxml1-0-bevocal.dtd">
	&gt;vxml version="2.0" xmlns:bevocal="http://www.bevocal.com/">
	&gt;form>
		&gt;prompt>Employee: &gt;/prompt>
		&gt;prompt><xsl:value-of select="/employee/name"/>&gt;/prompt>
		&gt;prompt>Works in the department: &gt;/prompt>
		&gt;prompt><xsl:value-of select="/employee/department"/>&gt;/prompt>
		&gt;prompt>He works out of: &gt;/prompt>
		&gt;prompt><xsl:value-of select="/employee/location"/>&gt;/prompt>
	&gt;/form>
	&gt;/vxml>
</xsl:template>
</xsl:stylesheet>

the problem is that I have to escape the "<" character since it isn't allowed in XML and I need to somehow convert it back to "<" in the resulting file.

btw, I'm using XT to work the magic.

Thanks a million!

I found it.

Code:

<xsl:text disable-output-escaping="yes">&lt;!DOCTYPE vxml PUBLIC "-//BeVocal Inc//VoiceXML 2.0//EN" "http://cafe.bevocal.com/libraries/dtd/vxml1-0-bevocal.dtd">

What I did was add a text XSL function(i don't know naming conventions) which printed out the DTD line for the XML and I had to escape the < at the beginning with <

this is awesome stuff!

From one XML file (which can be produced by a database server, like SQL-2000) I was able to produce a HTML and a VoiceXML file. very easy.

btw, I was reading into XSLT at the time that I ran across your article. talk about JIT. (just in time.)
