OK, so I have:
<xsl:variable name="DocRefINFO" select="( 'Project Name', 'Project ID', 'Sub
Project ID', 'tester' )"/>
<xsl:variable name="Lst" >
<xsl:for-each select="$root/html:tbody/html:tr[position()>1]">
<xsl:sequence
select="string(normalize-space(current()/html:td[1]/uci:par))" />
</xsl:for-each>
</xsl:variable>
then
<xsl:copy-of select="$DocRefINFO[not(.=$Lst)]"/>
returns whole $DocRefINFO
...when I debug, I have noticed Lst is sequence of Text types, whereas
DocRefINFO is sequence of string types;
I was trying to declare <xsl:variable name="Lst" as="xs:string"> but I get
error:
XTTE0570: Error in XPath 2.0 expression
Type error, value does not match a required type as specified by the
matching rules in 2.5.4 SequenceType Matching. - 'xs:string'
Which I guess is due to even though Lst would be declared as sequence of
strings, the way I assign values to it would make it rather a sequence of
Texts, which are incompatible to Strings?

If the two sequences of strings are $s1 and $s2,
$s1[not(. = $s2)]
returns all strings that are in $s1 and not in $s2.

Hello,
I have a another question:
I have one sequence. In runtime I generate another one.
Now I need a relative complement of the first to the second
(all the items that are in 1st sequence, but are not in the second).
The first sequence for me is tags that I need to generate in
the output. The second sequence is tags that I have found
data for in input, have processed them and have generated
tags to output. The relative complement is then the set of
tags of which data I did not encounter while processing
input, thus I need to generate them with some default values.
Is there some good way to do so? Should I be using some other
structure instead of sequences? (now I have a sequence of
strings that represent XML
tags)
Or other way, is it possible to extract items from the
sequence in runtime?
E.g. in a for-each loop? So that in the end that sequence
will contain only those tags that I did not find data for.
The problem I have now is if I use remove($list,index), then
it returns a new list without that item. I cannot change the
original list itself, the only thing I can do now to remember
this newly generated list is to recursively call the same
function again and give it this new list as the parameter.
However I see this as very uneffective, since then the
function will start the for-each loop again from the first
node and go through all the already processed data again...
The only way I have found to dynamically preserve in-loop
generated data is to <xsl:variable>
<xsl:for each>
<xsl:sequence> <--here I dynamically add data to that
variable
</for each>
</variable>
Thanks again for any advice,
Michael
