RE: Concat values

I started to look at your code and decided it would probably be better
to take your description of what you are trying to do and show you a
sample solution as opposed to actually trying work through your code and
adjust it as needed.  If the following code doesn't help with better
understanding how to create a solution that will work for you let me
know and Ill take another look at the actual code...

But in this particular case you've got the value of a variable that
needs to be compared to the value of an attribute in a sequence of
elements that have matched a certain XPath statement...  So if we start
there and move forward then I think we should still be on the page...

So heres our variable...

<xsl:variable name="attName" value="someValue"/>

And heres is where we are going to compare that variables values with an
attribute of each element that matches our XPath criteria.

But first we create a token element just so that we are sticking to a
set of good coding standards.  Then within that element we can create an
attribute with the proper name.  To cap off this portion of the code we
are going to select the items we are desirous to test against our
variables value and if they pass the test we are going to use the all
mighty power of xsl:apply-templates to send our little golden children
away to be buffed and shined and transformed into objects of shear
beauty.

So this code...

<xsl:element name="proudParentof_ExtendedAttributeDefinitionObjectLink">
        <xsl:attribute name="ExtendedAttributeDefinitionObjectLink">
                <xsl:apply-templates select="Frustrated_Child_of_
ExtendedAttributeDefinitionObjectLink[(_at_)compareMeTOattName = $attName]"/>
        </xsl:attribute>
<xsl:element>

<xsl:template match=" Frustrated_Child_of_
ExtendedAttributeDefinitionObjectLink">

<xsl:text> | </xsl:text><xsl:value-of select="."/>

</xsl:template>

Is going to give us this output...

<proudParentof_ExtendedAttributeDefinitionObjectLink
ExtendedAttributeDefinitionObjectLink=" | child_1 | child_2 | child_3"/>

Of which of course is invalid given the | to the left of child_1.  So to
fix that you would need to pass a parameter(well call it "pos" for
simplicity's sake) along with the apply-templates that contains the
value of its position() and then uses <xsl:if test="$pos &gt;
1"><xsl:text> | </xsl:text></xsl:if> to ensure that the first match to
the template doesn't get the | stuck in front of him/her.

So, if we put all the above together then we would have something that
looks like this...

<xsl:template match="/">
<xsl:element name="proudParentof_ExtendedAttributeDefinitionObjectLink">
        <xsl:attribute name="ExtendedAttributeDefinitionObjectLink">
                <xsl:apply-templates select="Frustrated_Child_of_
ExtendedAttributeDefinitionObjectLink[(_at_)compareMeTOattName = $attName]">
                        <xsl:with-param name="pos" select="position()"/>
                </xsl:apply-templates>
        </xsl:attribute>
<xsl:element>
</xsl:template>

<xsl:template match=" Frustrated_Child_of_
ExtendedAttributeDefinitionObjectLink">
<xsl:param name="pos"/>
<xsl:if test="$pos &gt; 1"><xsl:text> |
</xsl:text></xsl:if><xsl:value-of select="."/>
</xsl:template>

and this would give you the following output:
 
<proudParentof_ExtendedAttributeDefinitionObjectLink
ExtendedAttributeDefinitionObjectLink="child_1 | child_2 | child_3"/>

which should be similar to the output you are looking for and will
hopefully save your CPU a cycle or 12 as well :)

Hope this helps!

Best regards,

Subject: [xsl] Concat values

What I am trying to do is based on a value $attrName I need to check
every line item to see if this value exist in that Line Item.  If it
does exist for a particular line item I need to get the value of the
line item and pass it back and concatenate it with a | under a
particular attribute.

Hence I should produce something like this:

ExtendedAttributeDefinitionObjectLink="LineItem1|LineItem2|LineItem3"

Where are the Line Item names with a matching $attrName gets appended to
the Attribute above.
 


<xsl:attribute name = "ExtendedAttributeDefinitionObjectLink">
        <xsl:variable name="GroupLineItems" />

        I Loop through the line items here...
        <xsl:for-each
select="../../../../../ListOfRequestQuoteDetails/RequestQuoteDetails">
            <xsl:variable name="LineItem">

        I call the template below looping through the Reference of the
Line Item
                <xsl:apply-templates
select="RequestQuoteItemDetail/BaseItemDetail/ListOfItemReferences/ListO
fReferenceCoded/ReferenceCoded" mode="BidLineItems">

     
        Passing the template the value I have to match on.
                    <xsl:with-param name="fieldName"
select="$attrName"/>
                </xsl:apply-templates>
            </xsl:variable>

        Trying to concatenate... but of course this will not work
            <xsl:variable name="GroupLineItems"
select="concat($LineItem,'|')" />
        </xsl:for-each>
        <xsl:value-of select="$GroupLineItmes" />
</xsl:attribute>

My Template is below

<xsl:template match="ReferenceCoded" mode="BidLineItems">
    <xsl:param name="fieldName"/>
    <xsl:if test="ReferenceTypeCodedOther='QuestBidExtendedAttribute'">
        <xsl:if test="PrimaryReference/Reference/RefNum=$fieldName">
            <xsl:value-of
select="SupportingReference/Reference/RefNum"/>
        </xsl:if>
    </xsl:if>
</xsl:template>

Thanks... James
