Hi Guys,

I am using the below to get the first element from a "recognise text in image\PDF" output, is there a similar expression to get the second element?

Many thanks

Hi @dmgc,

You can use index numbers for this. [0] will also get the first element, [1] will get the second, [2] the third, etc.

So, in your case try:

item()['lines'][1]['text']

Hi @dmgc

You can try this:

first(take(skip(item()?['lines'],1),1))?['text']

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

@ManishSolanki @Expiscornovus , both work well, thanks.

As an aside, is there any expression to select First and Second element at the same time? Would save join operations that I am struggling with, seems the join goes badly for me! The join converts each array to string inside a new array element.

Eg:
Element 0
[
"I am the first page in the PDF. I am some junk text that I do not need, this",
"I am another page. I am some junk text that I do not need, this can be"
]

Element 1
[
"12341234",
"43214321"
]

Joined:
[
["I am the first page in the PDF. I am some junk text that I do not need, this","I am another page. I am some junk text that I do not need, this can be"]
["12341234","43214321"]
]

Hi @dmgc

If you want to merge the elements of both select results, then you can use createArray function. In the below expression, I have merged the results of 2 select actions with name 'Select 2' & 'Select 3' in compose action:

createArray(body('Select_2'),body('Select_3'))

This will return the following result in compose action:

[

    [

        "I am the first page in the PDF. I am some junk text that I do not need, this",

        "I am another page. I am some junk text that I do not need, this can be"

    ],

    [

        "12341234",

        "43214321"

    ]

]

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

Thanks
