XSLT Code for Custom Text

The product descriptions in the results for the example are derived from a small block of XSLT code

added to the “Snippet Box” section of the stylesheet. This custom block includes and augments the

default code for displaying the snippet. Note the differences and similarities in the default snippet box

and the customized version in these two examples:

Default Snippet Box

<tr>

<xsl:if test="$show_res_snippet != '0'">

<xsl:call-template name="reformat_keyword">

<xsl:with-param name="orig_string" select="S"/>

</xsl:call-template>

</xsl:if>

Custom Description Snippet Box

<tr>

<xsl:choose>

<xsl:when test="MT/@N='description' and MT/@V!=''">

<xsl:value-of select="MT[@N = 'description']/@V"/>

</xsl:when>

<xsl:otherwise>

<xsl:call-template name="reformat_keyword">

<xsl:with-param name="orig_string" select="S"/>

</xsl:call-template>

</xsl:otherwise>

</xsl:choose>

The custom description snippet block displays the description for each result that has a description

meta tag, or

. If the XSLT engine does not find a valid description tag, it calls the standard template

rules to display the auto-generated snippet element

The custom version includes the rule to display a standard snippet, but applies that template only if

there is no valid description tag in the result. If you use this approach, make sure you have only one

instance of the

reformat_keyword

template that selects the snippet element.

Description Meta Tag

Most of the product pages in this example includes a meta tag named

description

that contains a

brief description of the product. For example, the copper john nymph page includes this meta tag:

line nymphing. The high proportion of wire tied into the body makes the copper

john sink quickly to depth." />

All pages for which you want to present custom text must include a meta tag like the above example,

with the name properly referenced in the stylesheet and retrieved in the search request using the query

parameter

getfields

. For pages that do not contain valid description tags, the stylesheet uses the

automated snippet derived from page text.
