Re: [xsl] Resolving xsl:import href on different base URIs

2020-11-04 15:24:01
Thanks for all the suggestions! A static parameter and a shadow
attribute did the trick for me:

    <xsl:param name="apl:baseUri" as="xs:anyURI" static="yes"/>

    <xsl:import
_href="{resolve-uri('static/com/atomgraph/linkeddatahub/xsl/bootstrap/2.3.2/layout.xsl',
$apl:baseUri)}"/>

I didn't even know they existed, learned something new about XSLT 3.0
today :) The example in that section is pretty much what I needed:

Two further tricks:

(a) when you load the top-level stylesheet using new StreamSource(stream, 
systemId), the systemId becomes the base URI of the top-level stylesheet 
module, and this doesn't need to reflect the actual location of the source 
code.

(b) don't forget that you can set xml:base="" on either the xsl:stylesheet 
element or the xsl:import element,

Hi,

I have a stylesheet that I want to deploy on different setups that
have different base URIs. That impacts the relative URI of the
imports
of that stylesheet. For example, in one case

    <xsl:import href="../../../xsl/bootstrap/2.3.2/layout.xsl"/>

and in the other case

    <xsl:import
href="../../../../static/com/atomgraph/linkeddatahub/xsl/bootstrap/2.
3.2/layout.xsl"/>


In the first instance i'd consider seeing ifi could make the
environments closer,  and, if not, consder an external symbolic link.

Other alternatives include
* using a parameter (as Martin suggested) with _href="{ ....}"
* using an environoment variable, also with _href
 xsl:import _href="{ get-environment-
variable('PATHTOBOOTSTRAP')}/2.3.2/layout.xsl" />
or whatever (if you precompile the stylesheet, though, and deploy the
compiled bytecode, this probably won't help)

* using an XML Catalog
* using a wrapper stylesheet that calls fn:transform() on the real one,
after finding it.
