Concat 2 or more expressions

[tessej]

Hi folks,

I use the following expression as a filter for a RSS feed:

• @And(contains(string(item()?['title']), '[H/H]'),contains(string(item()?['title']), 'Microsoft'))

Now I want to add a second and maybe a third expression which needs to act as parallel filter options. So the second expression looks like this:

• @And(contains(string(item()?['title']), '[H/H]'),contains(string(item()?['title']), 'VMware'))

How can I 'connect' these two expressions so the filter gives the result for the first expression or the second expression or....

Kind regards

Hello @tessej ,

remove the @ from the expressions, put them into @or:

@Or(And(contains(string(item()?['title']), '[H/H]'),contains(string(item()?['title']), 'Microsoft')),And(contains(string(item()?['title']), '[H/H]'),contains(string(item()?['title']), 'VMware')))

*I hope I've got the brackets right

Each OR / AND can compare only 2 values/expressions, if you need more of them you must group them: e.g. evaluate the first two, then the result of the first two with the third, then the result of 1+2+3 with 4...

@or(expression1,expression2)
@or(or(expression1,expression2),expression3)
@or(or(or(expression1,expression2),expression3),expression4)
