<children xsi:type="Element" name="id" value="123"/>
<children xsi:type="Element" name="name" value="my name"/>
<children xsi:type="Element" name="is_a" value="345"/>
</children>

<children xsi:type="Element" name="Entity" value="">
<children xsi:type="Element" name="id" value="345"/>
<children xsi:type="Element" name="name" value="my other name"/>
<children xsi:type="Element" name="is_a" value="789"/>
</children>
....
</children>
and a target file like
<relation from_id="123" to_id="345" from_name="my name" to_name="my
other name">
....

but how do i get the to_name value from the other element?
i ve got a rule like:
rule entity{
from i : XML!Element (
i.name='Entity'
)outr0 : relation!relation(
from_id <-i.getvalue('id'),
to_id <-i.getvalue('is_a'),
from_name <-i.getvalue('name'),
to_name <-?????????????
),

with the helper
helper context XML!Element def : getvalue(finder : String) : String =
if self.children->select(c | c.oclIsKindOf(XML!Element) and
c.name=finder)->size()=0 then '' else self.children->select(c |
c.oclIsKindOf(XML!Element) and c.name=finder)->first().value endif;

Many thanks
Ina

You can define this helper:

helper def: getEntityNameFromId(entityId : String) : String =
XML!Element.allInstances()->select(e | e.name = 'Entity' and
e.children->select(c | c.name='id' and c.value= entityId)->notEmpty())
->first().children->select(c | c.name='name')->first().value;

And call it like this:

to_name <- getEntityNameFromId(i.getvalue('is_a'))

Sorry:

to_name <- thisModule.getEntityNameFromId(i.getvalue('is_a'))

with this helper i get an error if the id isnt found, so i added an if
clause to the helper:
now it works but it isnt very fast.

helper def: getEntityNameFromId(entityId : String) : String =
if XML!Element.allInstances()->select(e | e.name = 'Entity' and
e.children->select(c | c.name='id' and c.value=
entityId)->notEmpty())->notEmpty()
then XML!Element.allInstances()->select(e | e.name = 'Entity' and
e.children->select(c | c.name='id' and c.value= entityId)->notEmpty())
->first().children->select(c | c.name='name')->first().value
else ''endif;

many thanks for your contemporary help, this helper saved my day ;-)

Hi,

Concerning your helper performances, you should try to use a let
statement so that your time consuming request is evaluated only once.

fyi:
i changed it to this:

helper def: getEntityNameFromId(entityId : String, outname : String,
inname : String) : String =
XML!Element.allInstances()->select(e | e.name = 'Entity' and
e.children->select(c | if c.oclIsUndefined() then false else
c.name=inname and c.value= entityId endif)->notEmpty())
->first().children->select(c | if c.oclIsUndefinded() then false
else c.name=outname endif )->first().value;

(the outname and inname are only for being more flexible)
this changed the speed from over 25h (i canceld it after 10h and after
that it needed another 15h to end the process (it seems like it did the
transformation till the end) to 2h. (the input file is only 276KB big)
;-)

many thanks for your help
Ina
