i have been learning pipeline Pilot for a couple of weeks i am new with it and i have a question
hope can get help from you.

i want to access many Webpages (many URLs one by one not parallel) the format of webpages is XML
the target is to filter some content from every Webpage i figured out how to filter the Webpage using
xpath but the problem how can i send many URLs using XML-Component to open the Webpages one by one
to filter a content form them.

every URL has a changing part (id) in the address i create the URL at runtime using string append
operation

Example
https://pubchem.ncbi.nlm.nih.gov/rest/pug_view/categories/compound/id/XML, where id = 1,2,3 etc.

The problem is the XML-Component need in Parameter Window a value for Source like file or an address
like https://www.address.com because my URLs are a dynamic created URLs that means a URL is created at
runtime is there any possibility to save the value of the dynamic (at runtime ) created URL in a variable
and write this variable in the Source field inside Parameter Window for XML-Component ? i tried but got
Error or Exception may be i made a syntax mistake ?

--> pushing many URLs one by one to XML-Component to access a Webpage to filter some content of it.
Parameter Window for XML-Component need an address or file as source value doesn't accept a variable ?
save the address in a variable then write this variable as source inside Parameter Window.
 
best regards
