Any ideas how to solve this truncation thing.
Cheers Robert

Hey Robert,
While I wouldnt recommend this particular implementation for anything
larger than a "Breadcrumbs" XML source file(unless your mapping the
library of
congress most breadcrumb files should be somewhat manageable -- im
guessing yours is as well) here's what I used on the Saxon.NET project
site.
Heres the link to see the actual implementation:
http://www.x2x2x.org/x2x2x/home
The genearal idea... Create an XML that maps to your site structure that
starts with a "links" node as the main parent with all underlying
descendants
set to the name "link" and an "href" attribute set to the current
directory value (I use a relative reference) and then place the
reference to this
file within the document function and place that into a variable called
"links".
<xsl:variable name="links" select="document('links.xml')"/>
I then use a seperate "index.xml" that resides in each directory with an
element that contains the value of the current directory (in the same
relative format -- I usually set all of these to the root of the site by
using a preceding "/" such as "/x2x2x/home" instead of "x2x2x/home" but
thats
up to you and beyond the scope of your question as to which is more
appropriate for your situation. This index.xml contains all of the
necessary
content data the page for this directory correctly. It is passed to the
transformation process as the main data file to be transformed. As such
I
can just set the following param (used to compare with the href value of
each "link" element until a match is found) to the location of that
element
like so: (Note: This is the same general idea that you are using the id
attribute for although the xml parser will notice the id attribute as a
unique
identifier where as my method will not... depending on your future needs
or what else you may use the id attribute for you can decide which is
more
appropriate for your particular case)
<xsl:param name="curDir" select="/page/curDir"/>
I chose to reference the above as an xsl:param in case you decide to
pass this value as a parameter via whatever implemenation you are using
to
transform your file. It will work either way but if you choose to
implement it the way I did then I would change it to a xsl:variable
instead to
ensure a more consistent practice of proper use throughout your projects
development.
The params from above are passed into this code block which outputs the
appropriate bread crumbs and then continues the transforation of the
rest of
the stylesheet. As you can see, with an embedded xsl:for-each element
and a reference to all descendant-or-self "link" elements using "//link"
this
is definitely not something you want to use with a large data source to
process through :)
<xsl:for-each select="$links/links//link[(_at_)href =
$curDir]/ancestor-or-self::link">
<xsl:variable name="href">/x2x2x<xsl:for-each
select="ancestor-or-self::link">/<xsl:value-of
select="@href"/></xsl:for-each></xsl:variable>
<a href="{$href}" class="locationA"><xsl:value-of
select="@common"/></a> <xsl:if test="position() != last()"> >
</xsl:if>
// by the way, the @common attribute value used above is the
common or friendly name for the directory
// using capitalized first letters and spaces between each word
in the directory name. Its part of each link element. </xsl:for-each>
And that should do it...
Hope this helps!
Regards,

Hello,
what I am trying to do is create a breadcrumb trail based on a current
page id and a sitemap XML document. In my page.xml I have a
placeholder
tag:
<?xml-stylesheet type="text/xsl"
href="generate-breadcrumb.xsl"?>
...
<add-breadcrumb pageid="ID5"/> <--------- final breadcrumb
HTML fragment should go here
...
Based on its @pageid the first XSL(generate-breadcrumb.xsl) generates
this XML fragment:
<breadcrumb>
<item url=""area1.xml" label="area1"/>
<item url=""area2.xml" label="area2"/>
<item url=""areaN.xml" label="areaN"/>
<page label="thisPage"/>
</breadcrumb>
To do styling and truncation task based on the page width, I need to
send this fragment through a Second XSL (style-breadcrumb.xsl) which
generates the actual HTML fragment which then be should placed in the
page.xml.
How can I realise this 2-step transformation. Any ideas are welcome.
Best regards,
Robert
