qwerty3321 Posted November 26, 2018 Report Posted November 26, 2018 Hello there, i want to learn about writing and retrieving data in xml can anyone tell me where can i start with Thank you Quote
crossrulz Posted November 26, 2018 Report Posted November 26, 2018 1. Help->Find Examples. Do a search for XML 2. Go look at packages in VIPM. NI has a Simple XML library that I used to figure some things out. Then JKI and MGI have their own XML packages you can have a look at. 1 Quote
Benoit Posted November 27, 2018 Report Posted November 27, 2018 What is your final goal with the XML? Benoit Quote

qwerty3321 Posted November 27, 2018 Author Report Posted November 27, 2018 Specifically i need to fetch and write the names and the values from the xml Quote
Benoit Posted November 28, 2018 Report Posted November 28, 2018 So since it is quite generic, I will suggest you as crossrulz said and learn the basic stuff about xml standard. It is not difficult. you can even inside of a week create your own parser. Benoit Quote
qwerty3321 Posted November 28, 2018 Author Report Posted November 28, 2018 I want to indicate the names and values of test 1 and test 2 in table Could you help me please new xml.txt Quote
Benoit Posted November 28, 2018 Report Posted November 28, 2018 Do a match pattern on those: "<Name>Test 1</Name> <NumElts>" and then on "<NumElts>" By getting the character position in the file, you can easily replace the value in between with anew one. repeat with <Name>Test 2</Name> But why do you want to replace those value? are they already real measurement from real device? I have Ethical concern on what you are trying to do. Benoit Quote
qwerty3321 Posted November 28, 2018 Author Report Posted November 28, 2018 i dont want to replace those values . i just want to indicate them on the front panel along with the names p.s These values are constants Quote
Benoit Posted November 28, 2018 Report Posted November 28, 2018 well then the way I explained to you is the same... instead of replacing, report it. ? Benoit Quote
qwerty3321 Posted November 28, 2018 Author Report Posted November 28, 2018 I'm really sorry but im really new to this. Which file palette do i need to use ? Is it the XML parser ? Quote
Benoit Posted November 28, 2018 Report Posted November 28, 2018 (edited) For the simple task you want to do, just use search pattern. It should looks like this... Benoit Edited November 29, 2018 by Benoit Quote

It is corrupted (There are many stray "-" characters, so XML parsers will give you an error) Also, take the time to follow @crossrulz's advice: On 11/26/2018 at 6:46 PM, crossrulz said: 1.

Benoit Posted November 28, 2018 Report Posted November 28, 2018 Since his xml document is not standard, I suggest him to use search pattern instead... so no matter is the txt file format/standard, it will work. Benoit Quote

Benoit doesnt it make complex using search pattern? i need to give each name and value in string array constant Quote
Benoit Posted November 28, 2018 Report Posted November 28, 2018 No matter what tools you will use, you need to define what value you want... If you use xml tools, it will be similar. Benoit Quote
qwerty3321 Posted November 28, 2018 Author Report Posted November 28, 2018 can you show me how to fetch the name and value of two elements of cluster test1 and test2 using xml palette please new xml.txt Quote

Like I said before, your XML file is corrupted. The XML palette won't work on it. Quote
