Synopsis

               string
               string
               string*
               )

Inputs

Two or more strings.

Output

The concatenation of all of the input strings.

Defined in

XPath section 4.2, String Functions.

Example

We’ll use this XML file to demonstrate how concat() works:

<?xml version="1.0"?>
<list>
  <title>A few of my favorite albums</title>
  <listitem>A Love Supreme</listitem>
  <listitem>Beat Crazy</listitem>
  <listitem>Here Come the Warm Jets</listitem>
  <listitem>Kind of Blue</listitem>
  <listitem>London Calling</listitem>
  <listitem>Remain in Light</listitem>
  <listitem>The Joshua Tree</listitem>
  <listitem>The Indestructible Beat of Soweto</listitem>
</list>

In our stylesheet, we’ll use the concat() function to create filenames for various JPEG files. The filenames are composed from several pieces of information, concatenated by the concat() function:

<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:variable name="newline"> <xsl:text> </xsl:text> </xsl:variable> <xsl:template match="/"> <xsl:value-of select="$newline"/> <xsl:for-each select="list/listitem"> <xsl:text>See the file </xsl:text> <xsl:value-of select="concat('album', position(), '.jpg')"/> <xsl:text> to see the title of album #</xsl:text> <xsl:value-of select="position()"/> <xsl:value-of select="$newline"/> ...
