Re: [xsl] Dynamic image and text alignment

["M. David Peterson" <m.david.x2x2x@xxxxxxxxx>]

xml-input of:

<?xml version="1.0"?>
<form-data>
  <form>
    <field id="foo" value="This is a string of text aligned on the
right" align="right" image="foo.gif" image-width="100px" 
image-height="100px" />
    <field id="bar" value="This is a string of text aligned on the
left" align="left" image="bar.gif" image-width="100px"
image-height="100px" />
  </form>
</form-data>

xsl-stylesheet 0f:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:template match="/">
  <xsl:apply-templates select="form-data/form"/>
</xsl:template>
<xsl:template match="form">
  <div>
    <xsl:apply-templates select="field"/>
  </div>
</xsl:template>
<xsl:template match="field">
<xsl:variable name="opposite-float">
<xsl:choose>
  <xsl:when test="@align = 'left'">
    <xsl:text>right</xsl:text>
  </xsl:when>
  <xsl:otherwise>
    <xsl:text>left</xsl:text>
  </xsl:otherwise>
</xsl:choose>
</xsl:variable>
  <div style="clear:both">
    <div style="float:{$opposite-float}">
      <img src="{@image}" style="width:{@image-width};
height:{@image-height}" />
    </div>
    <div style="float:{@align}">
      <xsl:value-of select="@value"/>
    </div>
  </div>
</xsl:template>
</xsl:stylesheet>


gives the output of:

<div>
  <div style="clear:both">
    <div style="float:left">
      <img style="width:100px; height:100px" src="foo.gif"/>
    </div>
    <div style="float:right">This is a string of text aligned on the right</div>
  </div>
  <div style="clear:both">
    <div style="float:right">
      <img style="width:100px; height:100px" src="bar.gif"/>
    </div>
    <div style="float:left">This is a string of text aligned on the left</div>
  </div>
</div>

This should get you started in the right direction.

Cheers!
