Thanks you for your help Michael, you have been an invaluable help
It4s correct? I like to process one formulary to search records . I solved
so:
/************** XHTML *************/
<form method="post" action="procesar.bsb" id="search">
<input type="text" name="date" id="date" size="14" maxlength="10"/>
<input type="text" name="name" id="name" size="31"/>
<p class="opcion">
<input type="checkbox" name="beca" value="111111" id="beca" />
<label for="checkbox2">Becas</label></p>
<p class="opcion">
<input type="checkbox" name="conferencia" value="222222" id="checkbox8"
/>
<label for="checkbox8">Conferencias</label></p>
<p class="opcion">
<input type="checkbox" name="others" value="" id="others" />
<label for="checkbox10">Others</label></p>
</fieldset>
<p><input type="submit" name="Submit" value="Buscar" class="boton"/></p>
</form>
/************** XSL *****************
<xsl:param name="name"></xsl:param>
<xsl:param name="beca" select="000000"></xsl:param>
<xsl:param name="conferencia" select="000000"></xsl:param>
<xsl:param name="others" select="000000"></xsl:param>
<xsl:variable name="date" select="20080205000000"></xsl:variable>
<xsl:variable name="filter" select="//RecursoEx1[F_FIN=$date and
(CLASIFICACION=$beca or CLASIFICACION=$conferencia or CLASIFICACION=$others)
and contains(TITLE,$name)] | //RecursoEx1[F_FIN=$date and (CLASIFICACION=*
and $beca=000000 and $conferencia=000000 and $others=000000) and
contains(TITLE,$name)]"></xsl:variable>
************* XML ****************

Asunto: RE: Cannot process a result tree fragment as a node-set under
XSLT 1.0 - My alternative don4t function
It's not always possible to get by without using result tree fragments but
it is possible in this case. And in general, if you can write
<xsl:variable name="x">
<xsl:when test="condition1">
<xsl:copy-of select="exp1"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="exp2"/>
</xsl:otherwise>
</xsl:variable>
then you can probably replace it with
<xsl:variable name="x" select="exp1[condition1] | exp2[condition2]"/>
which avoids the cost of copying the nodes, and avoids the RTF problem.
Of course an even better solution is to move to XSLT 2.0.

Hi Michael,
Thank you so much for the quick response.
Michael >>However, it's not clear to me that you need to
create an RTF in the first place. Why not define $filter as
<xsl:variable name="filter" select="//RecursoEx1[($option=1 and
F_FIN=$date1 and contains(TITULO,'o')) or ($option=2 and
F_FIN=$date2)]"/>
I want to count the RecursoEx1 elements:
<p>Number: <xsl:value-of
select="count(exsl:node-set($filter)/RecursoEx1)"/></p> CORRECT!
I want to iterate over the RecursoEx1 elements:
<xsl:for-each select="exsl:node-set($filter)/RecursoEx1">
CORRECT !
I use xsl:copy-of and exsl:node-set because to error "Cannot
process a result tree fragment as a node-set under XSLT 1.0"
if i code :
<xsl:variable name="filtro">
<xsl:choose>
<xsl:when test="$option=1">
<xsl:copy-of
select="//RecursoEx1[F_FIN=$date1]"/></xsl:when>
<xsl:otherwise>
<xsl:copy-of
select="//RecursoEx1[F_FIN=$date2]"/></xsl:otherwise>
</xsl:choose>
</xsl:variable>
<p>Number: <xsl:value-of select="$filter"/></p>
<xsl:for-each select="$filter">
<p><xsl:value-of select="TITULO"/></p>
</xsl:for-each>
and i don4t know if exits another posibility. Exists??
The variable "option" is to received from one formulary, but
there are more and then the "filter" will be dynamic.
How can i do to construct the filter dynamic? For example, i
receive one varible named "title" from the formulary with the
value: "John Martin Car Monday" and i like to enumerate the
RecursoEx1 elements that meet with this
condition: TITLE=John or TITLE=Martin or TITLE=Car or TITLE=Monday.
or title variable is Apple Pencil, ..... then the condition
will be TITLE=Apple or TITLE=Pencil
i don4t know how may parameters i will receive in advance..
Thanks again Michael,
Alexander

Asunto: RE: Cannot process a result tree fragment as a
node-set under XSLT 1.0 - My alternative don4t function
The node-set returned by the exsl:node-set() function will
always contain a single (document or root) node. Perhaps you
wanted its children:
exsl:node-set()/*.
However, it's not clear to me that you need to create an RTF
in the first place. Why not define $filter as
<xsl:variable name="filter"
select="//RecursoEx1[($option=1 and F_FIN=$date1 and
contains(TITULO,'o'))
or ($option=2 and F_FIN=$date2)]"/>
Note also, that horrible bit of disable-output-escaping can
be avoided by setting the doctype-system and doctype-public
attributes on xsl:output.
