[xsl] Re: xsl-list Digest 7 Apr 2005 05:10:00 -0000 Issue 380

[Shivani Goel <goelshivani@xxxxxxxxx>]

Thanks Michael, David. You were both prompt and accurate... I appreciate it greatly!

Michael said:
Try adding quotes, e.g. 'abcdefghijklmnopqrstuvwxyz'

which worked perfectly. However there is little quirk (annoying one, at that) that I wanted to
report, and perhaps someone could explain it: It seems the following do not function exactly
identically:

<xsl:if test="@name[not (translate (., '$lowerCase', '$upperCase') = translate
following::Program/@name, '$lowerCase', '$upperCase'))]"> 

$lowerCase & $upperCase are defined as follows:

 <xsl:variable name="upperCase" select="ABCDEFGHIJKLMNOPQRSTUVWXYZ"/>
 <xsl:variable name="lowerCase" select="abcdefghijklmnopqrstuvwxyz"/>

                ____ versus ____

<xsl:if test="@name[not (translate (., 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')
= translate (following::Program/@name, 'abcdefghijklmnopqrstuvwxyz',
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'))]"-->

The second <xsl: if> works fine (in that 'project oregon' and 'Project Oregon' nodes in my XML
source/dataset are recognised as identical, ie the translate () is performed perfectly/as
intended).

*Not So* with the first <xsl: if> where I use variables instead of the string 'A...Z'

Not that both refer to nodes /axes in the exact same manner. Any ideas why?

Many thanks,
Shivani.

I've been through this list (and also googled my
query), but am wits end as why my code doesnt work:

This is a fragment from my XML file:

<Program name="project oregon">
...
..
</Program>
<Program name="project oregon">
..
...
.......
</Program>
<Program name="Project Oregon">
.......
........
.......
</Program>
<Program name="Spring Beach Cleanup">
..............
.........
</Program>
<Program name="Spring Beach Cleanup">
...
</Program>

I want to display the value of attr 'name', in an HTML
<select> element (aka drop down list), while
eliminating duplicates, for which, I do this:

<select class="formDropDown1" name="program"
id="program">

<xsl:if  test= "@name [not (self::node() =
following::Program/@name)]">

<option>

    <xsl:attribute name="value"><xsl:value-of
select="@name"/></xsl:attribute>
    <xsl:value-of select="@name" />
						</option>
						    </xsl:if>

The above works flawlesslessly to eliminate duplicates
(though from what I've read, using 'following' axis
may lead to pefomance issues with very large XML
files...).

However, *and this is my reason for posting to the
list*, I want to have "project oregon" and "Project
Oregon" display only once! I tried the following to
translate the respective nodes to identical (upper)
case, as follows:

<xsl:if test="@name[not(translate (self::node(),
abcdefghijklmnopqrstuvwxyz,
ABCDEFGHIJKLMNOPQRSTUVWXYZ) = translate
(following::Program/@name, abcdefghijklmnopqrstuvwxyz,
ABCDEFGHIJKLMNOPQRSTUVWXYZ))]" >

This does NOT work! Duplicates are eliminated,
however, "project oregon" & "Project Oregon " are
treated as separate /unique strings. What am I doing
wrong?

Any suggestions will be gratefully welcome.

Shivani.

  <xsl:if  test= "@name [not (self::node() =
  following::Program/@name)]">

self::node() can be written more simply as .

  translate
  (following::Program/@name, abcdefghijklmnopqrstuvwxyz,
  ABCDEFGHIJKLMNOPQRSTUVWXYZ))]"

This has come up already today (and is a faq) lthough I'm not sure what
you'd search for. If you use a node set as an argument to a string
function xslt1 takes the first node in document order in the set and
uses that nodes string value, it ignores any other nodes.

it (might be) a bit more efficient or at least clearer  to use
following-sibling on the element node rather than following from the
attribute node,

test="@name=following-sibling::Program/@name"
tests if this nodes name attribute is equal to any of the following
nodes names.

test="translate(@name,$u,$l)=translate(following-sibling::Program/@name,$u.$l)"
tests if this nodes name attribute is equal to the _immediately
following_ Program nodes name attribute.

In this case you can do

test="following-sibling::Program/@name[translate(.,$u.$l) =translate(current()/@name,$u,$l)]"

Try adding quotes, e.g. 'abcdefghijklmnopqrstuvwxyz'
