4. XSLT
PB138
XSLT
● people.xml + people.xsl = xsl-result.html
● 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 /people
● 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>
Template Priority
<xsl:template match="person[@name=’Filip’]"
priority=”2”> <!-- highest priority -->
....
</xsl:template>
<xsl:template match="person”
priority=”1”>
....
</xsl:template>
Processing Modes
<xsl:template match="person[@name=’Filip’]"
mode=”nameBlue”>
....
</xsl:template>
<xsl:apply-templates mode="nameBlue"/>
Modes, foreach and IFs
● <xsl:choose>
● <xsl:if>
● <xsl:for-each>
Functional calling
● create a table "id, name"

● 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:
