Re: [Nant-users] string::get-length problem

[Ian MacLean]

this:
test="${string::get-length('${modifications}') 

should be
test="${string::get-length(modifications)}"
by using quotes you are just getting the length of the literal string 
'${modifications}'
note ${} syntax does not nest. '${}' excloses a complete expression and you reference 
properties by name inside it - ie without re-using $ syntax

Hi there,
if I do the following :
                       <property name="modifications" value=""/>
                       <xmlpeek  file="albwir.basis.modifications.xml"
xpath="/vssdiff/item[1]/@name"
                                               property="modifications"
                                               failonerror="false"/>
                       <echo message="${modifications}"/>
                       <if test="${string::get-length('${modifications}') >
1}">
                                  <echo message="Doh! Not empty that string
is! The force you must use."/>
                       </if>
                       <property name="modifications" value=""/>
                       <echo message="Now empty modifications is!"/>
                       <echo message="${modifications}"/>
                       <if test="${string::get-length('${modifications}') >
1}">
                                  <echo
message="${string::get-length('${modifications}')}"/>
                                  <echo message="That is modifications :
${modifications}"/>
                       </if>
Then, in the second <if>, string::get-length returns the same like before.
But ${modifications} HAS changed.
Am I doing something wrong here or is this a bug? I’m using nant 0.85
