Subject Fix for images in Petstore
Date Mon, 19 May 2003 22:50:28 GMT
I fixed a minor problem with the Petstore example app. The images 
associated with each pet would not display.

Would someone with CVS access please check this in. Thanks,


In the stylesheet I added one attribute (disable-output-escaping="yes") 
to the xsl:value-of in the 'item' template:

 In /cocoon/samples/petstore/stylesheets/site2html.xsl please modify. 
(Better this than sending a hugh file with one change)
...
    <xsl:template match="item">
        <p>
            <table align="center" bgcolor="#008800" cellspacing="2" 
cellpadding="3" border="0" width="60%">
                <tr bgcolor="#FFFF88">
                    <td bgcolor="#FFFFFF">
  <!-- Edit this line  -->     <xsl:value-of select="product-desc" 
disable-output-escaping="yes" />
                    </td>
                </tr>
                <tr bgcolor="#FFFF88">
                    <td width="100%" bgcolor="#cccccc">
                      <b><xsl:value-of select="@id" /></b>
                    </td>
                </tr>
...
--------------------

In the sitemap I added a pipeline to handle JPG files. I also added some 
additional views and view labels to make it easier to understand how to 
use views.
