The Wireless Markup Language (WML) is a smaller and less powerful variant of HTML, conceived as the display markup for mobile phones and PDAs. Details can be found in column12.
<?xml version="1.0" ?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0">We changed the output method, although WML is not a recognized method yet and therefore currently ignored. We're planning ahead for when this will change.
<xsl:output method="wml"/>
<xsl:template match="/">
<WML><CARD ID="id1" TITLE="RSS newsfeed">
<xsl:apply-templates/>
</CARD></WML>
</xsl:template>
Here we change the familiar structure of HTML and BODY into the WML version of
WML and CARD.
<xsl:template match="channel">
<DO TYPE="accept">
<xsl:attribute name="LABEL">
<xsl:value-of select="title"/>
</xsl:attribute>
<GO>
<xsl:attribute name="HREF">
<xsl:value-of select="link"/>
</xsl:attribute>
</GO>
</DO>
</xsl:template>
<xsl:template match="item">
<DO TYPE="accept">
<xsl:attribute name="label">
<xsl:value-of select="title"/>
</xsl:attribute>
<GO>
<xsl:attribute name="HREF">
<xsl:value-of select="link"/>
</xsl:attribute>
</GO>
</DO>
</xsl:template>
<xsl:template match="text()"/>
</xsl:stylesheet>
Finally we need to replace the TABLE and A anchor formatting with the DO/GO pair of
tags specified in WML. The finished product is RSS2WML.
If you have a WAP-enabled mobile phone or a WAP development
toolkit you can look at the WML output.
XSL is a flexible solution for converting an XML-based input format such as RSS into various output formats. The case study here demonstrated the transformation into HTML with CSS and WAP/WML. Non-XML based output such as RTF, PDF, GIF etc. is also possible, and we might get back to this topic in a later installment of this column.
