Description

When I use the document() function in saxon-js to try to access a relative file path on the web server It cannot find the path as I expected and I need to put a full path in with the domain to make it work. I think this may be a bug or if not it would be a nice feature to add the context here!

I noticed this when I call a function requesting the path along the lines...

[...] <xsl:result-document href="#svg" method="ixsl:replace-content"> <xsl:copy-of select="foo:output-svg(.)"/> </xsl:result-document> [...]

The function then must have the full path using the function as follows:

<xsl:function name="foo:output-svg" expand-text="no"> <xsl:param name="content"/>
<xsl:apply-templates mode="svg" select="document('/floorplan.svg')"/> </xsl:function>

Yes, you need to be careful using relative URIs. Please see the information under "Relative URIs" at http://www.saxonica.com/saxon-js/documentation/index.html#!development/source-documents. In particular, the last paragraph:

"We recommend using absolute URIs rather than relative URIs to avoid any mix up - for instance resolve against ixsl:location() to fetch a document relative to the HTML page, using doc(resolve-uri($relativeURI, ixsl:location())) rather than doc($relativeURI) (which will be resolved against the static-base-uri())."

So rather than using a relative path, always construct the right absolute path yourself. There's also an example under http://www.saxonica.com/saxon-js/documentation/index.html#!ixsl-extension/functions/location

Note that doc(), and document#1 when given a string literal argument, resolve against the static base URI of the stylesheet. This in turn depends on whether you specified -relocatable when compiling the stylesheet. Generally a lot of the W3C spec is written on the assumption that the stylesheet is executed at the same location where it is compiled, and we've had to adapt the rules for a different scenario.

Note also that document() also has a two-argument form, so rather than use resolve-uri() explicitly, you can also specify the node whose base URI is to be used in the second argument.
