Re: [xsl] Best practices - using vars

[David Carlisle <davidc@xxxxxxxxx>]

> 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=
