start with xml data

[qwerty3321]

Hello there,

i want to learn about writing and retrieving data in xml

can anyone tell me where can i start with

Thank you

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.

What is your final goal with the XML?

I have an xml document.

i would like to read and write back that xml file in labview

[qwerty3321]

Specifically i need to fetch and write the names and the values from the xml 

[Benoit]

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.

I want to indicate the names and values of test 1 and test 2 in table

Could you help me please

new xml.txt

[Benoit]

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

[qwerty3321]

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

[Benoit]

well then the way I explained to you is the same... instead of replacing, report it. ?

Benoit

[qwerty3321]

I'm really sorry but im really new to this.

Which file palette do i need to use ? Is it the XML parser ?

[Benoit]

For the simple task you want to do, just use search pattern.

It should looks like this...

Where did you get this XML document from? 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:

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.

doesnt it make complex using search pattern? i need to give each name and value in string array constant

[Benoit]

No matter what tools you will use, you need to define what value you want...

If you use xml tools, it will be similar.

Why do you refuse to use the code that @Benoit already wrote for you?

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

I would like to know the process of using the xml palette assuming i have a valid xml file

Thank you

Open LabVIEW and click Help > Find Examples... then search for "XML". @crossrulz gave you this advice earlier.
