I think i misunderstood the all thing, and the example isn't good as well...
Let me try again:
<xsl:variable name="form-base" select="/Formatos/Forms/Form[1]" />
returns a node that i can later use like this:
<xsl:variable name="MasterTable" select="$form-base/MasterTable"/>
But if i have
<xsl:variable name="form-base">
<xsl:value-of select="/Formatos/Forms/Form[1]" />
</xsl:variable>
then i have a string representation of the childnodes of
/Formatos/Forms/Form[1], and i can't use it to further go down the tree?
Quoting xptm(_at_)sapo(_dot_)pt:
In the particular case of xtabnode i realy want a node to be passed as
argument
to a Java method (that expects a org.w3c.dom.Node).
In the other cases, tought, you're saying it's best to use
<xsl:variable name="sqlInsert" select="sql:getStatement($MasterTable, $sql,
$where, $where, $xtabnode, 'I' )" />
instead of
<xsl:variable name="sqlInsert">
<xsl:value-of select="sql:getStatement($MasterTable, $sql, $where,
$where,
$xtabnode, 'I' )" />
because the first returns a string and the second a node with a node text
that
contains a string?
Did i understand correctly?
Quoting David Carlisle <davidc(_at_)nag(_dot_)co(_dot_)uk>:
What is the cost of using vars? I'm doing this, for instance:
higher if you use them as you have with content rather than a select
attribute.
<xsl:variable name="xtabnode">
<xsl:value-of
select="document(concat('.\DicionarioXml\',$MasterTable,'.xml'))/Estrutura/Tabelas/Tabela[Nome=$MasterTable]"/>
</xsl:variable>
produces a result tree fragment with a root node and child a text node
with string value the string you want. When this result tree fragment is
used, it has to be coerced back to a string.
<xsl:variable name="xtabnode">
select="document(concat('.\DicionarioXml\',$MasterTable,'.xml'))/Estrutura/Tabelas/Tabela[Nome=$MasterTable]"/>
is less to type and makes the variable have (a pointer to) the Tabela
node in the specified document.
or perhaps
<xsl:variable name="xtabnode">
select="string(document(concat('.\DicionarioXml\',$MasterTable,'.xml'))/Estrutura/Tabelas/Tabela[Nome=$MasterTable])"/>
in which case the variable holds the string value itself.
similarly all your other variable declarations should have select=
