Re: Search example

Hi Ryan,

some time ago you send me a XPL for my search-request and now i have some questions, cause it doesn't work so far :-(

 

in my page-flow i entered the following line:

<page id="search01" path-info="/search/service/search_exist" view="search01.xpl"></page>

 

when sending my submission, the URL is:

http://localhost:8085/kkbib-new/search/service/search_exist?search-criteria=test

 

the submission is:

<xforms:submission id="search01" ref="xxforms:instance('search01-instance')" method="get" action="/search/service/search_exist" replace="all" show="new" />

 

the code i copied from you is:

 

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline" xmlns:oxf="http://www.orbeon.com/oxf/processors" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xdb="http://orbeon.org/oxf/xml/xmldb"

xmlns:lw-p="http://www.puddzy.com/namespaces/lorna-web/products">

    <p:param name="instance" type="input"/>

    <p:param name="data" type="output"/>

 

<p:processor name="oxf:xslt-2.0">

    <p:input name="data" href="#instance"/>

    <p:input name="config">

<xdb:query xsl:version="2.0" collection="/db/kkbib">

xquery version "1.0";

declare namespace xmldb=http://exist-db.org/xquery/xmldb;

import module namespace t=http://exist-db.org/xquery/text;

declare namespace demo=http://www.mbeddow.com/demo;

declare namespace fn=http://www.w3.org/2003/05/xpath-functions;

declare option exist:serialize "highlight-matches=elements method=xhtml media-type=application/xhtml+xml";

 

<xsl:variable name="search-criteria">

    <xsl:choose>

        <xsl:when test="contains(/search-criteria,' ')">

        (

            <xsl:for-each select="tokenize(/search-criteria,' ')">

                '<xsl:value-of select="."/>'

                <xsl:if test="not(position() = last())">,</xsl:if>

            </xsl:for-each>

        )

        </xsl:when>

        <xsl:otherwise>

            '<xsl:value-of select="/search-criteria"/>'

        </xsl:otherwise>

    </xsl:choose>

</xsl:variable>

 

<result>

    <term>

        <xsl:value-of select="$search-criteria"/>

    </term>

{

let $hits := collection('/db/kkbib/forms')//form[text:match-any(.,<xsl:value-of select="$search-criteria"/>)]

for $hit in $hits

return

$hit

}</result>

 

</xdb:query>

</p:input>

<p:output name="data" id="search-query" debug="SQ"/>

</p:processor>

 

<!-- query exist for products -->

<p:processor name="oxf:xmldb-query">

    <p:input name="datasource" href="datasource.xml"/>

    <p:input name="query" href="#search-query"/>

    <p:output name="data" ref="data"/>

</p:processor>

</p:config>

 

But my result-page show an empty <term>-tag, so that the search-criteria = '' and for that, nothing is searched :-((

Can you help me with that a point me to the failure?

 

Thanks, Marcus

Subject: Search example

Marcus,
    This example, takes a submitted instance (from the instance param) and passes this into an xslt processor, the instance is one element

<search-criteria>my search</search-criteria>

The XSLT creates a variable which splits the search criteria into seperate tokens to match on, the above would be ('my','search')

The xquery predicate uses the match-any function against a sequence of name and description fields, the function is match-any(sequence-to-search,criteria-sequence-string), then it returns the results. If you want to check what the xslt, a debug (SQ) is produced depending on you Log4J settings.

Finally the xquery is sent off to exist using xmldb-query, passing all the necessary params (check OF docs for more info on this)

HTH, if you need any more direction feel free to email me

Ryan
