Using the following to pull back a list of events sub pages
<xsl:for-each select="$currentPage/descendant::* [ @isDoc and string(umbracoNaviHide) != '1' and umbraco.library:DateGreaterThanOrEqualToday(umbraco.library:DateAdd(pageDate, 'd', eventDuration)) ]">
Is there any way to make the eventDuration have a default value of zero? Similar to in T-SQL
isNull(eventDuration, 0)
I'd rather not be running a check from inside the 'loop'
Your could write your own extension method for it, where you pass eventDuration and return 0 if the input is empty or null.
Can I take that as a 'No' in answer to my question?
Edit: That wasn't meant half as snippily as it sounds
Well, you could call the extension method in the for-each select, but you will indeed have to make it yourself.
It's a very small amount of work tho.
Just create a class with
public static string WithDefault (string input, string default) { return string.IsNullOrEmpty(input) ? default : input; }
Build and add dll in the bin folder.
Then add a line to xsltExteions.config. See:
http://en.wikibooks.org/wiki/Umbraco/Create_xslt_exstension_like_umbraco.Library_in_C
In the for-each loop, I'm adding a variable which I'm then testing assigning a value if
MY_VALUE = '' or MY_VALUE = NaN
Then using an if before each block of content
Is there really no way to do this check in the fore-each select?
Hi Tony,
I guess you could do something like this:
<xsl:decimal-format name="Nullify" infinity="0" NaN="0" /> <xsl:template match="/"> <xsl:for-each select="$currentPage/descendant::* [@isDoc] [not(umbracoNaviHide = 1)] [umbraco.library:DateGreaterThanOrEqualToday( umbraco.library:DateAdd(pageDate, 'd', format-number(eventDuration, '0', 'Nullify')) )]"> <!-- Do stuff --> </xsl:for-each> </xsl:template>

Nice. I've now learnt something new.
Although, I've abandoned that approach as something in the next step made it easier for me to go back and change how I was doing stuff

An equivalent to isNull?
