I'm having difficulties as to how I should parse this kind of csv file.
For example:

"London","United Kingdom","City Of London, Greater London",51.517,-0.106,7421228,http://www.worldweatheronline.com/London-weather/City-of-London-Greater-London/GB.aspx
For example, I need to get the first two values on the first line, all the values on the 2nd to 6th line, and the first value of the 7th line.
I currently have a model class with properties for all the values I need to get.
I'm not sure how to do it in this situation. So far, I know how to parse that csv (if I didn't need to get the first two values on the 1st line, and the first value of the 7th line)
What would be the logic to parse in this situation? Hope you guys can give me some idea how to do it.
Thanks
Split the string into lines (busing a scanner or array method depending on how big the string is). Once you have your lines, takes the special ones and pass to appropriate methods to extract the required values. Likewise for the main lines.
You can use your parser on each line individually or use a scanner or array method if that's easier depending on what content you need to extract and where it is.

I was wondering if folks have found a reliable way to inject text into an existing string. Some context, I'm writing data to a string indicator formatted like a table, and I wanted to inject values into so they maintain a specific format, spacing-wise. Writing to a table would definitely be easier, however I am porting a legacy program and wanted to provide familiarity to the end user.
Essentially, I want to do the equivalent of typing into a .txt file with the INSERT function enabled, where it just overwrites the content already in the string. Example below (dashes added to show spacing) of how it is currently looking when I inject the values with hard coded spacing:
Time---value---avg. value---result
60------10---------20---------PASS
120------11---------20---------PASS
180------9---------15---------FAIL
I'd prefer it to look more lined up, like below:
Time---value---avg. value---result
60------10---------20---------PASS
120-----11---------20---------PASS
180-----9--------- 15---------FAIL
Writing my application using LabVIEW 2019
Edit: Header will obviously not change, only each subsequent line where the values can result in entries not looking lined up
What about "Replace Substring" function (https://zone.ni.com/reference/en-XX/help/371361R-01/glang/replace_substring/)? Doesn't it meet your requirements?
The diagram below outputs 01234999990123PASS890123456789. The values of the integer and the word PASS are added replacing characters in the existing string, exactly like overstrike would do.
I'm trying to clear an array after each iteration of a for loop in LabVIEW, but the way I've implemented it has the values not going directly to what I want, but it changes with previous values in other parts of the array.
It isn't shown, but this code is inside of a for-loop that iterates through another numeric array.
I know that if I get the array to clear properly after each loop iteration, this should work. How do I do that? I'm a beginner at Labview but have been coding for awhile - help is appreciated!!!

It looks as if you're not quite used to how LabVIEW passes data around yet. There's no need to use lots of value property nodes for the same control or indicator within one structure; if you want to use the same data in more than one place, just branch the wire. Perhaps you're thinking that a LabVIEW control or indicator is equivalent to a variable in text languages, and you need to use a property node to get or set it. Instead, think of the wire as the variable. If you want to pass the output of one operation to the input of another, just wire the output to the input.
The indicators with terminals inside your loop will be updated with new values every loop iteration, and the code inside the loop should execute faster than a human can read those values, so once the loop has finished all the outputs except the final values will be lost. Is that what you intended, or do you want to accumulate or store them in some way?
I can see that in each loop iteration you're reading two values from a config file, and the section is specified by the string value of one element of the numeric array Array. You're displaying the two values in the indicators PICKERING and SUBUNIT. If you can describe in words (or pseudocode, or a text language you're used to) what manipulation of data you're actually trying to do in the rest of this code, we may be able to make more specific suggestions.
First of all, I'm assuming that the desired order of operations is the following:
Putting the value of Pickering into Array 2
Extracting from Array 2 the values to put in Pickering 1 and Pickering 2
Putting Array 2 back to its original value
If this is the case, with your current code you can't be sure that operation 1 will be executed be fore operation 2. In fact, the order of these operations can't be pre-determined. You must force the dataflow, for example by creating a sequence structure. You will put the code related to 1 in the first frame, then code related to operation 2 in the second.
Then, to put Array 2 back to it's original value I would add a third frame, where you force an empty array into the Value property node of Array 2 (the tool you use for pickering, but as input and not as output).
The sequence structure has to be inside the for loop.
I have never used the property node Reinit to default, so I can't help you with that.
Unfortunately I can't run Labview on this PC but I hope my explanation was clear enough, if not tell me and I will try to be more specific.
I am new to ABAP.
I have a requirement in abap.In my presentation server ,there is header text file, which I want to upload data from that text file to Header table. But the custom table is having different structure from text file.
It includes extra 4 fields- PO_CREATED_DATE, PO_CREATED_BY, PO_CHANGED_DATE, PO_CHANGED_BY.
These fields have to populate from our report program using sy-datum and sy-uname.
In this scenario,we have to check,If the data is existing then populate
PO_CHANGED_DATE, PO_CHANGED_BY and if the data is not there,then populate PO_CREATED_DATE, PO_CREATED_BY.
Please let me know the logic...
first load the file into an internal table with only 1 very long field (long enough to contain at least the longest possible line in the file). Then loop over that itab and split the individual lines using the separator that is used in the file. You split the contents into a work area that contains all your fields, including the 4 extra fields that may or may not be included in the file. Make sure to clear the work area before splitting the line into the WA. Append the work area to an itab with the same structure as the wa, then continue with the next line.
After that, loop over that second itab and check for lines where your 4 extra fields are initial. Those are the lines where you need to add the data by code. After that, do whatever you need to do with the data in the itab.
I uploaded text file header data to it_input1 using gui_upload.But the it_input1 is not having extra 4 fields.I declared another itable it_header which is having the same structure as Header custom table.Now i wnt to check whether the data in the it_input 1 is alredy existing or not.If existing ,populate it_header-po_changed_date and it_header-po_changed_by or else, it_header-po_created_date and it_header-po_created_by.
Take a look to the "Pattern" Button on top. Select ABAP Objects an press enter.
Now you can supply the class and methdo you want to call.
CL_GUI_FRONTEND_SERVICES=>GUI_UPLOAD
GUI_UPLOAD is a static method. If you are new that is the easiest way to see which parameters must be supplied. With the forward navigation (double-click) you can check the signature for typing the parameter variables.
Then you just need to convert your data (e.g. SPLIT). I can only recommend to use the F1-Help.
Kind regards!
Coding in Objective-C, I'm appending text to a NSTextView object named subCap in my code like so:
[[[_subCAP textStorage] mutableString]appendString:[NSString stringWithFormat:#"%#", subcapLine]];
subcapLine will have two timecode values such as: "01:00:00:00 01:00:01:00" separated by a single space, then a newline (\n) character, then a string like "ONC314_001_001" followed by two newline chars (\n\n).
The end result will create a list similar to:
01:00:00:00 01:00:01:00
ONC314_001_001
01:00:01:00 01:00:02:00
ONC314_001_002
01:00:02:00 01:00:03:00
ONC314_001_003
etc, etc, etc.
It's a sub caption file for placing text (the ONC314 lines) at appropriate times in a video file, as indicated by the timecodes.
However, I've determined that there is an odd set of circumstances where a timecode pair could be the same as the previous timecode pair, and if that happens, I want to skip appending that line.
So, my question is, given that the timecodes are always 11 chars apiece, separated by a space, can anybody think of a way I can easily grab the prior TC pair and compare it to my current pair in the subcapLine I'm preparing to append? The problem is the text of the sub caption could be random lengths. In my example they're the same, but that isn't always the case.
If I need to check prior to compiling my subcapLine, I can do that too, but I just thought it might be more slick to use a range of some sort to grab the prior pair of TCs from the last-written line in the NSTextView object and compare (again, using a range?) against the TCs in the line I'm about to append?
Thoughts and suggestions much appreciated.

When you add a timecode store the length of the text field string just before you add the timecode so you will have the offset to the timecode you are about to add.
Then before adding a new timecode you could simply use the previous offset you stored to extract the substring and do a string comparison and see if the timecodes are identical.
This should allow you to always have an offset to the previous timecode regardless of the length of the subtitles.
I have over a hundred text files and I need to change the construction of several sentences using a specific format. I am not very familiar or experienced with Word VBA but I hope I could get some ideas to help me get started. I have below the original paragraph and its desired output. Basically I need to place the values (e.g. 40-120 parts) after each item (e.g. isoleucine) and enclose those with "(" and ")".
Original: An acid combination for increasing immunity, comprising the following raw materials by weight: 40-120 parts of isoleucine, 45-135 parts of leucine, 76.5-229.5 parts of lysine hydrochloride, 21.5-64.5 parts of methionine, 35-105 parts of phenylalanine, 40-120 parts of valine, 30-90 parts of threonine, 39-117 parts of arginine, 23-69 parts of histidine, 37.5-112.5 parts of glycine, 50-150 parts of aspartate, 900-2700 parts of dried mushroom, 750-2250 parts of medlar and 250-750 parts of licorice.
Desired Output: An acid combination for increasing immunity comprises (pts.wt.): isoleucine (40-120), leucine (45-135), lysine hydrochloride (76.5-229.5), methionine (21.5-64.5), phenylalanine (35-105), valine (40-120), threonine (30-90), arginine (39-117), histidine (23-69), glycine (37.5-112.5), aspartate (50-150), dried mushroom (900-2700), medlar (750-2250) and licorice (250-750).
Maybe you could try the following sequence :
Find the part you want to change (numbers seperated by - and parts) with the Find function (another link) and a well-formed regexp (meant wildcards for Word)
Set the brackets at the beginning and at the end of the matched element (use the range object)
Delete the last word ("part") - or whatever you want to do
Loop through every results to do the same (see an example of looping through find function here)
Don't forget you can record macro if you are looking for some tips or specific objects (even if the code produced is less complete than the one produced by Excel vba).
Please don't hesitate to post some code if you want some more help,
