4. XSLT
PB138
XSLT
● messages.xml + messages.xslt = result.xml
● XSLT is composed of templates.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.
org/1999/XSL/Transform">
<xsl:template match="/">
Running the Transformation
● Try transformation from Netbeans and from
Java
● HELLO WORLD
Basic Transformations
● / vs /messages
● Evaluation of the algorithm
○ apply-templates will again apply the whole template
file to each child
○ text() matching
● The implicit templates
○ We can override them!
Implicit Templates
<xsl:template match="*|/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="text()|@*">
<xsl:value-of select="."/>
</xsl:template>
Functional calling
● create a table "id, text"
○ sms text in red color
○ other text in blue
Modes, foreach and IFs
● Write out SMS first!
● <xsl:choose>
● <xsl:if>
● <xsl:for-each>
Other important concepts
● xsl:sort
● xsl:element
● xsl:call-template (with parameters)
xsl:element, xsl:attribute
<xsl:element name="{@element}">
<xsl:attribute name="id">ID1</xsl:attribute>
● Output the names in "id" elements:
