Hi,
I have a list of points point(0), point(1), point(2) ... and i will to retrieve them in a xml templater like this:
<listPoint>
for $i in (1 to {fme:get-attribute("_element_count")}) return {fme:get-attribute("point[$i]")}
</listPoint>
I don't succeed with this writing ...
The values contained inside point{} are floats.
the result desired is like this one :
<listPoint > 0,75534 0,4455 0,4532 0,67556 </listPoint >
Each value is separated by a space.
I have a counter to know how many points i have to write (_element_count).
But for the loop "for" i have a problem to write it in a Xml templater
OK. You can easily convert the values contained by FME list attribute to XML list (space separated values) with the fme:get-list-attribute function. Try this expression.
<listPoint>{fme:get-list-attribute("point{}")}</listPoint>Hi
When i put this :
<listPoint>{for $i in (1 to {fme:get-attribute("_element_count")}) return $i}</listPoint>
it give me an error :
XMLTemplater_2(XMLTemplaterFactory): The following error occurred near line 2, column 32 of the query:
XMLTemplater_2(XMLTemplaterFactory): xs:string can not be promoted to parameter type xs:integer? of function to()
But when i put this :
<listPoint>{for $i in (1 to 10) return $i}</listPoint>
it gives me <listPoint>1 2 3 4 5 6 7 8 9 10 </listPoint>

<listPoint>{fme:get-list-attribute("point{}")}</listPoint>I have to test inside the list and extract by example the fifth element

I have to test inside the list and extract by example the fifth element
<listPoint> {for $i in (1 to xs:integer({fme:get-attribute("_element_count")})) return $i} </listPoint>
it output a xml fragment in 2 records :
<listPoint> 1 2 3 4 5 6 7 8 </listPoint>
<listPoint> 1 2 3 4 5 6 7 8 9 10 </listPoint>
In my two records, i have a list in each one, with 8 points for the first, 10 points for the second.
I have to made a test, depending on $i to verify that the point($i) is not negative. If it's the case, i have to extract this point($i), but i don't know the position in advance
<listPoint> {for $i in (1 to xs:integer({fme:get-attribute("_element_count")})) return $i} </listPoint>

<listPoint>{
for $v in fme:get-list-attribute("point{}")
where 0 < xs:double($v)
return $v
}</listPoint> Hi,
Is this good depending the test i have to do on the value of "i" in the list if i want to retrieve only certain values of points and output them in :
<listPoints>
if ( $i ==2 or $i ==5)
{fme:get-attribute(concat("point{", $i, "}"))}
</listPoints>

return $p
