Because I want to pass a string containing an absolute route to a file as parameter to a Xslt Template which open the document specified in the parameter, I need a way of converting such string into a route using a catalog
I explain in Code
currently I have an Uri like this "https://www.bancaonline/banco_santander"
I need convert it into "file:/c:/bancos/santander/clientes.xml"
so I introduce the change in catalog
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public">
<rewriteURI uriStartString="https://www.bancaonline/banco_santander"
rewritePrefix="file:/c:/bancos/santander/clientes.xml" />
</catalog>
later I create in XSLT file a variable route with the first URI in order to use "$route" as parameter
<xsl:variable name="route" select="https://www.bancaonline/banco_santander" />
but I receive the following error Unexpected token ":" beyond end of expression I think that the Uri is not normalized, could you help me to get the variable route working and receiving the correct Uri by the catalog.

Hi Francisco,

How about if you post a small sample (XSLT + XML + XML catalog) to better exemplify the situation? Because I have no idea at what line in the stylesheet the error "Unexpected token ":" beyond end of expression " occurs.

I Detail the Error
XSLT File
<xsl:template match="/">
<xsl:variable name="route" select="https://www.bancaonline/banco_santander/clientes.xml" />
<!-- here yields the error Unexpected token ":" beyond end of expression -->

<xsl:result-document href="{$rutaDocumentoSalida}" method="xml" encoding="UTF-8" indent="yes" >
<xsl:apply-templates select="document($rutaDocumentoEntrada)" >
<xsl:with-param name="uriPuntoEntrada" select="$route" tunnel="yes" />
</xsl:apply-templates>
</xsl:result-document>
</xsl:template>

The Catalog
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public">
<rewriteURI uriStartString="https://www.bancaonline/banco_santander" rewritePrefix="file:/c:/bancos/santander/" />
</catalog>

Hi,

When you want to have an XSLT variable which has as value a string literal you need to surround the literal with extra simple quotes like this:

Thanks Radu, now it works, but I see that the catalog only works when using document
so <xsl:variable name="route" select="document('https://www.bancaonline/banco_santander/clientes.xml"')" />
is transformed into file:/c:/bancos/santander/clientes.xml
but <xsl:variable name="route" select="'http://www.animales/domesticos/europa/perros.xml'" /> is not transformed
and my question is if document function is allways required for the transformation or there are other XSL commands or functions that can be used too
for the catalog transformation.

Hi,

Good question.
I've used in the past quite a lot the capabilities of the document() function to automatically resolve through the XML catalog, but from what I know the XSLT resolve-ur() function does not although maybe it should, I asked a question about this on the Saxonica (XSLT Processor) issues list:
https://saxonica.plan.io/issues/5277
I'm not sure why you want to pass that URL reference through the XML catalog and keep it as a plain string, maybe you can elaborate.
Anyway you could probably do something like this as a workaround: Also some resources about XSLT training:
