Developing FileMaker XSLT stylesheets 61
Using the Web Publishing Engine base URI parameter
The Web Publishing Engine defines the base Uniform Resource Identifier (URI) parameter to be the host
and port where the Web Publishing Engine is installed. The base URI allows requests for XML data from
FileMaker databases to be resolved in relation to the Web Publishing Engine host.
To access the Web Publishing Engine base URI, include this statement in your XSLT stylesheet before the
top
<xsl:template> element:
<xsl:param name="xml-base-uri"/>
You can then use the base URI for the current stylesheet via the $xml-base-uri variable whenever you need
to make an additional request for FileMaker XML data. For example, you can use the base URI in the
following request for additional XML data:
<xsl:variable name="layout_information" select="document(concat($xml-base-uri,'/fmi/xml/FMPXMLLAYOUT.xml?
–db=products&–lay=sales&–view'))" />
Using the authenticated base URI parameter
The authenticated-xml-base-uri parameter combines the functionality of the client-user-name and client-
password
parameters with the xml-base-uri parameter:
<xsl:param name="authenticated-xml-base-uri"/>
Use this parameter to load an additional password-protected XML document that requires the same user
name and password that was specified in the original request currently being processed. For an example, see
the next section,
“Loading additional documents.”
Include this parameter statement in your XSLT stylesheet before the top <xsl:template> element.
If the values for the client-user-name and client-password parameters are not blank, then the value of the
authenticated-xml-base-uri parameter is:
http://username:password@hostname:port
If the values for the client-user-name and client-password parameters are blank, then the value of the
authenticated-xml-base-uri parameter is the same as the value of the xml-base-uri parameter.
Loading additional documents
To load an additional XML document during the processing of an XSLT stylesheet, use the standard XSLT
document() function with a URI to the XML document. The document() function returns the requested XML
as a
node-set that can be stored in an <xsl:variable> element.
To load an XML document that contains data from a FileMaker database, use the document() function with
FileMaker query command and parameters. For example:
<xsl:variable name="other-data" select="document(concat($xml-base-uri,'/fmi/xml/FMPXMLLAYOUT.xml?
–db=products&–lay=sales&–view'))"/>
To load an additional password-protected XML document that requires the same user name and password
that was specified in the original request currently being processed, use the
authenticated-xml-base-uri
parameter. This parameter specifies the same user name and password as part of the URI that is passed to
the
document() function.
For example:
<xsl:variable name="other-data" select="document(concat($authenticated-xml-base-uri,
'/fmi/xml/FMPXMLLAYOUT.xml?–db=products&–lay=sales&–view'))"/>
