RE: Split with delimiter and remove duplicate using XS

Hi Folks,

Yes, xslt 2.0 is great and solves problems.  But I've had to get distinct values with an xslt 1.0 requirement (and no
extensions) numerous times.  I've posted a blog entry on this with an example.  It uses a delimited list and then
interates through the list using a template.

http://www.xmlhelpline.com/blog/stories/2007/05/06/xslt10GroupingIteratingAndUniquenessWithoutKeys.html

It isn't elegant, but it works.  Xslt 1.0 and no extensions nor keys.
For what its worth.

Cheers,
Paul

Subject:  Split with delimiter and remove duplicate using XSL 1.0

Hi all!

I am new to XSL programming and I was tasked to solve the problem I stated on my subject.
As i was browsing the mailing list, i chanced upon this reply

Martin Wrote: I would first tokenize, then use xsl:for-each-group to remove duplicates:

Perfect. I am going through the tutorials to understand <xsl:for-each-group> and it use. Still needs to look into the
correct usage of current-group() and current-group-key(), group-by , group-adjacent etc. <xsl:copy-of
select="current-group()[1]"/>

Time to get seriously involve myself in exploring 2.0. :-)

Thanks again Martin.

I know that this problem can be solved using functions in XSL 2.0 like tokenize, the use of regular expressions and
etc.. but my question is, can it be solved using purely XSL 1.0 functions?
(without the use of tokenize and regex)

Example.

If i have this tag:

<sample>
...
...
<text>[1]Sample Text 1[2]Sample Text 1[3]Sample Text 2</text>

...
...
</sample>

How can i get this output? The text would be parsed using [] as the delimiter then remove duplicate values (Sample Text
1)

<out>Sample Text 1</out>
<out>Sample Text 2</out>


Any suggestions?

Thanks a lot in advance.
