I am trying to use VTL for the first time and cannot see to get arrays to grab an inputted String.
I have tried "in" (but I do not believe this is a key word in this language), as well .contains() below (but it does not find the string inside the created array)
Code Below for Use Case Reference:
#set($MSpanish = ["Argentina", "Belize"])
#elseif($MSpanish.contains(${lead.Country}))
#set($subject = "hellow world")
What keyword would I use instead of contains? Is there any keyword that would save the time of many if statements with == in VTL?

I'm trying to look for specific keywords inside of text from a for each loop.
var text = "The lazy fox jumped over the brown dog."
var keywords = "fox,dog,sun";
If true, I want to do something with the text. If false, I want to ignore the text.
Does anyone know how to use an Array filter, Function, Select, Condition or inline code to check for this? If so, specific examples would be great.
By the way, I have a C# function that handles this extremely well in an ASP.net Core app.
UPDATE 1:
This doesn't work.
UPDATE 2:
The Condition is always false after the for each loop even after changing the settings and parallelism to 1.
Azure Logic App Condition does not work in loop if based on changing values
Thanks in advance!
There are so many ways to achieve what you need. Here are the 3 options that came to my mind within a minute.
The first one does use a For each loop, but I wouldn't recommend using it as it's not very efficient.
The For each parameter looks like this:
The Condition parameter looks like this:
The second option is much easier - no need for a loop, just filter the array straight away, then you can check whether it's empty or it has some items:
The Filter array parameters look as follows.
The split function is identical to the one used in option 1.
If you know JavaScript, you might decide to use regular expressions in inline code instead, e.g.:
Then you'd just need to check the output of the inline code. JavaScript code used in the example above:
var text = workflowContext.actions.Compose_text.outputs;
var keywords = workflowContext.actions.Compose_keywords.outputs;
return text.match(new RegExp("(" + keywords.split(",").join("|") + ")", "gi"));
My personal preference is option 2. However, please note that all 3 options above would find "sun" in text "The weather was sunny" even though there's no word "sun" in the text. If you do need "sun" to match only word "sun" - not "sunny", "asunder" or "unsung" - then go for option 3, just use a different, more complex regular expression.
One of the workaround would be use of Condition Connector. I have initialized the sentence in a string and then used Condition Connector which will be checking the conditions.
Finally, In the true section you can add the connectors accordingly.
Placing a Compose behind the for each loop and referencing the Output in the Condition is what finally worked for me. I used the toLower() function in my Compose. The Compose looks like this.
toLower(items('For_each_2')?['day']?['longPhrase'])
I've been following the guide on Exceljet for how to create a recursive LAMBDA function that removes all numbers from a string. For example, A1B2C3D4E5 becomes ABCDE.
The only thing I wanted differently was to have the string containing the character omissions stored inside the function rather than the cell. So, I took away the chars parameter from the opening line and used the LET function to store the string.
The problem is I keep getting a #VALUE! error and can't work out why.
=LAMBDA(str,sub,
LET(chars,"0123456789",
IF(chars="",str,
ReplaceChars(
SUBSTITUTE(str,LEFT(chars),sub),
MID(chars,2,LEN(chars)-1),
sub
)
)
))
A nested LET() in a recursive LAMBDA() is going to be troublesome since every time you'd use the variable in the recursion you'd start from scratch. Replacing characters will therefor never stop (if my interpretation of this is correct). But in your case you don't even need to make a recursive LAMBDA() to replace numbers, for example:
=LAMBDA(str,LET(X,MID(str,SEQUENCE(LEN(str)),1),CONCAT(IF(ISNUMBER(X*1),"",X))))
Core of this function is now:
=LET(X,MID(A1,SEQUENCE(LEN(A1)),1),CONCAT(IF(ISNUMBER(X*1),"",X)))
which can be used outside of LAMBDA() just fine. We can even replace this with
=LET(X,MID(A1,SEQUENCE(LEN(A1)),1),CONCAT(IF(ISNUMBER(FIND(X,"0123456789")),"",X)))
to do the same thing with any character you want to replace.
Now you can call =REPLACECHARS(A1). However, IMHO the beauty of the use of variables is now lost and the original approach (for example here would have my personal preference.
I'm using OpenRefine to pull in information on publisher policies using the Sherpa Romeo API (Sherpa Romeo is a site that aggregates publisher policies). I've got that.
Now I need to parse the returned JSON so that those with certain pieces of information remain. The results I'm interested in need to include the following:
'any_website',
'any_repository',
'institutional_repository',
'non_commercial_institutional_repository',
'non_commercial_repository'
These pieces on information all fall under an array called "permitted_oa". For some reason, I can't even work out how to just pull out that array. I've tried writing grel expressions such as
value.parseJson().items.permitted_oa
but it never reutrns anything.
I wish I could share the JSON but it's too big.
I can see a couple of issues here.
Firstly the Sherpa API response items is an array (i.e. a list of things). When you have an array in the JSON, you either have to select a particular item from the array, or you have to explicitly work through the list of things in the array (aka iterate across the array) in your GREL. If you've previously worked with arrays in GREL you'll be familiar with this, but if you haven't
value.parseJson().items[0] -> first item in the array
value.parseJson().items[1] -> second item in the array
value.parseJson().items[2] -> third item in the array etc. etc.
If you know there is only ever going to be a single item in the array then you can safely use value.parseJson().items[0]
However, if you don't know how many items will be in the array and you are interested in them all, you will have to iterate over the array using a GREL control such as "forEach":
forEach(value.parseJson().items, v, v)
is a way of iterating over the array - each time the GREL finds an item in the array, it will assign it to a variable "v" and then you can do a further operation on that value using "v" as you would usually use "value" (see https://docs.openrefine.org/manual/grel#foreache1-v-e2 for an example of using forEach on an array)
Another possibility is to use join on the array. This will join all the things in an array into a string.
value.parseJson().items.join("|")
It looks like the Sherpa JSON uses Arrays liberally so you may find more arrays you have to deal with to get to the values you want.
Secondly, in the JSON you pasted "oa_permitted" isn't directly in the "item" but in another array called "publisher_policy" - so you'll need to navigate that as well. So:
value.parseJson().items[0].publisher_policy[0].permitted_oa[0]
would get you the first permitted_oa object in the first publisher_policy in the first item in the items array. If you wanted to (for example) get a list of locations from the JSON you have pasted you could use:
value.parseJson().items[0].publisher_policy[0].permitted_oa[0].location.location.join("|")
Which will give you a pipe ("|") separated list of locations based on the assumption there is only a single item, single publisher_policy and singe permitted_oa - which is true in the case of the JSON you've supplied here (but might not always be true)
I need to iterate and parse 108 lines from a file and then sort them into 3 different hashes. (In one iterator.) (In Ruby)
I have the file loaded into the program and into the array I need to parse. When I try to make the iterator anyway I try to use the Regex Match command I get an error abut the unknown method. Is as simple that I can't use that method on a array?
lines = File.readlines('access_log')
lines.each.match(/^([:\d\.]+) .*\[.*\].*\"[A-Z]+ *(.+) HTTP/)
This and every other way I have tried to use the match method it hasn't worked.
This also doesn't anything for the hash, as I haven't done that yet.
/^([:\d\.]+) .*\[.*\].*\"[A-Z]+ *(.+) HTTP/.match(lines)
Have also tried this, but the error output appears that you cant run it on only the array. I beilive this is where I would need to tie the iterator in, but I'm stumped.
So, what's happening is that what readlines does is it slurps the entire text file.
So you have an array with the content of the textfile separated by a newline(and the newline is kept in every string in the array).
After that, you're doing lines.each, which brings out an enumerator. Then you're calling .match on the enumerator instead of the string itself
The proper way to do this would be
lines.each { |line| line.match(/^([:\d\.]+) .*\[.*\].*\"[A-Z]+ *(.+) HTTP/) }
However, the above actually won't do anything because all you're doing is iterating against each element and checking if it matches the REGEX.If you want it to actually do something, try...
matches = lines.map { |line| line.match(/^([:\d\.]+) .*\[.*\].*\"[A-Z]+ *(.+) HTTP/) }
Remember that the match method only works on strings. If match matches something, it returns an object of the class MatchData, else if it doesn't match anything-- nil.
I cannot seem to find anything about using the values of one property of an object in a foreach loop (without having the entire object placed into the loop).
I first create a function called UFGet-Servers that uses Get-ADComputer and returns the names of the servers in a specific OU in my environment and places them in an array. That's great, except that when I use the array in a foreach loop, each object that it grabs has #[Name=serverName] in it, which I cannot use in any useful manner. The following pseudo-code is an abbreviated example:
foreach($Computer in $ComputerNames){do code... code is adding the server name into a UNC path such as "\\$Computer\C$\"}
The problem with the above is that you can't add the whole object to a path -- it ends up looking like "\#[Name=serverNameHere]\C$\" which totally bombs out. How do I get rid of the "#[property=" part, and simply use the value as the $Computer in the loop?
What really weirds me out is that I can't find a straightforward article on this anywhere... would have thought everyone and their mom would have wanted to do something like this.
So, your issue isn't with ForEach loops, it is with string formatting. There are two ways that I know of to take care of what you need. First is going to be string formatting, which allows you to use {0}m {1} and so on to inject values into a string, providing that you follow the string with -f and a list of said values. Such as:
ForEach($Computer in $ComputerNames){
"The Server Path is \\{0}\Share$" -f $Computer.Name
}
The second way is a sub-expression (I'm sure somebody will correct me if I used the wrong term there). This one involves enclosing the variable and desired property (or a function, or whatever) inside $(). This will evaluate whatever is inside the parenthesis before evaluating the string. See my example:
ForEach($Computer in $ComputerNames){
"The Server Path is \\$($Computer.name)\Share$"
}
