No IfIn for a simple array?

[newbieforever]

Hi!

array := ["one", "two", "three"]

Is there really no direct way to check if "two" is an element of the array (so that a loop must be used)?

Yesterday I searched exactly for the same problem and found this:

But it didn't work for me. HTH you.

Hi!

array := ["one", "two", "three"]

Is there really no direct way to check if "two" is an element of the array (so that a loop must be used)?

here is a pretty direct way:

v2

Code: Select all

array := ["one", "two", "three"]
for key, value in array
	if InStr(value,"two")
		MsgBox("The string  > " value " <  was found.")
return

v1

Code: Select all

array := ["one", "two", "three"]
for key, value in array
	if InStr(value,"two")
		MsgBox % "The string  > " value " <  was found."
return

You could also do

v2

Code: Select all

array := ["one", "two", "three"]
,	InStr(array[2], "two") ? MsgBox("The string  > " array[2] " <  was found.") : MsgBox("The string  > two <  was  NOT found.")
return

v1

Code: Select all

array := ["one", "two", "three"]

if (InStr(array[2], "two"))
	MsgBox % The string  > " array[2] " <  was found."
else	
	MsgBox % "The string  > two <  was  NOT found."
return

Thank you, Kobaltaugte & Tigerlily!

So I summarize: There is no "direct way" (in the sense of my question)...

Hm.. my second method was extremely direct...

this may be the most direct way:

You could even do this in v2:

Code: Select all

MsgBox(InStr(array := ["one", "two", "three"][2], "two"))

resolves to 1, meaning string was found!

@Tigerlily: But of course this was meant to mean that you don't know in advance that it is the 2nd element.
Or, for a better understanding of my question:


array := ["one", "three", "two"]

Is there really no direct way to check if "four" is an element of the array (so that a loop must be used)?

I'm a little confused .. are you asking if you can directly check WITHOUT a loop? or WITH a loop?

what do you mean by direct way?

[newbieforever]

Direct = without a loop.

v2

Code: Select all

i := 1, InStr(array := ["one", "two", "three"][i], "two") ? MsgBox("found in index # " i ) : i++, InStr(array := ["one", "two", "three"][i], "two") ? MsgBox("found in index # " i ) : i++, InStr(array := ["one", "two", "three"][i], "two") ? MsgBox("found in index # " i ) : i++, InStr(array := ["one", "two", "three"][i], "two") ? MsgBox("string not found in any index") : { }

[toralf]

If you could put the values as keys (they must be unique) then you could use .HasKey()

[Tigerlily]

v2

Code: Select all

a:=["one","five","two"],(InStr(a[1],"four")!=0)||(InStr(a[2],"four")!=0)||(InStr(a[3],"four")!=0)||(InStr(a[4],"four")!= 0)?MsgBox("found"):MsgBox("not found")

[A_AhkUser]

Without loop (using the strrept string hack by jeeswg):

Code: Select all

array := ["one", "two", "three"]

MsgBox % hasValue(array, "two") "`n"
		. hasValue(array, "Two", false) "`n"
		. hasValue(array, "Two", true) "`n"
		. hasValue(array, "thre") "`n"
		. hasValue(array, "one") "`n"

hasValue(arr, value, caseSensitive:=false) {
return !!InStr(Format("|" StrReplace(Format("{:" ObjCount(arr) "}", "")," ","{:}|"), arr*), "|" value "|", caseSensitive)
}

As for me, I think the better way is using a loop.

The solution of @toralf I found here yesterday to.
https://stackoverflow.com/questions/33591667/how-to-check-if-string-is-contained-in-an-array-in-autohotkey/33593563
But I have the same issue. I'm iterating though hundreds/thousand of XMLs. My goal was to push on specific element in an array. And then going on with

Code: Select all

If "new element" is in array {
do this
}

I didn't find a proper solution without looping through the array. But as you can imagine after a while it took a while. =)

can you use querySelector/querySelectorAll?

Code: Select all

myDoc.querySelector("[*|id='toto']")

Will return an empty string if the object is missing, but if its there will be node[0]

[toralf]

If the check (IfIn) is required more often. You can have the normal Array as you have right now and create a Value Array where the values are the keys. Then you can check in the values Array. Of course, you’ Have to keep the two arrays in sync.

Ps: the value Array could have the xml path as values

[Kobaltauge]

Thank you for your feedback.
I don't want to hijack this thread, but I don't know how to get your solution to run.
Additionally, hope I understand what you are doing, I don't want to find a specific value in a bunch of XMLs. I'll try to search in all the XML for double values.
Therefor I tried to read all the values in one array and search for an existing one.
But it doesn't matter, don't waste more time on my issue. I found another solution. And if I need your solution in future I'll post a new thread.

Thank you. This was exactly what I tried, but I didn't get it to work. So I found another soultion involving a csv file and Excel
I have still so much to learn.

[toralf]

You will have to use the xml values as keys in the AHK associated Array

[swagfag]

regular ahk arrays u gotta loop over to find specific values, theres no way around that
u can stuff ur values in an associative array like toralf suggested, but ull lose the order of insertion and case sensitivity. identical values will also overwrite previous one.
if u need to preserve these properties, ull have to implement ur own ordered hashmap

Why are you using arrays instead of xpath if it's an XML document
