Converting XML String to MessageElement array

Hi,
I am trying to call a .NET web service from my Java client. I used WSDL2Java to generate the java classes for calling the .NET web service. The generated classes to call the service expects an array of org.apache.axis.message.MessageElement objects. I have a string representing an XML document which looks like this:
String xmlString = "<Results><Adjustments><Adjustment><RebuildAdjustmentID>16</RebuildAdjustmentID><IsBasicAdjustment>true</IsBasicAdjustment><AdjustmentType>stone/AdjustmentType><Title>External walls</Title></Adjustment></Adjustments></Results>"
I have tried converting the string into an array of MessageElement objects by the following way:
MessageElement[] m = new MessageElement[1];
Document XMLDoc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(result2.toString())));
m[0] = XMLDoc.getDocumentElement();
However I keep getting the following message returned from the service:
"Object reference not set to an instance of an object"
I have tried a handful of ways but keep getting this same error. I have searched the web for hours looking for a solution to this problem without success so any help/ideas much appreciated,
Thanks.
Paul

Any updates on this?

I want to convert a String into an array of bytes

I am working with telnet programming with java, where I want to convert login name and password of an online user in 'String' format to 'Bytes', plz help me. Which Input or Output Stream I can use

Assuming you've got the username / password into a String object, you can convert it to a byte[] array using this method.
String.getBytes();
Look at the String API
http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html
Hope that helps.

How to convert a String to an array

Can somebody tell me how to convert a String to an array

Can you not simply look at the API documentation? Nothing in the String API jumps out at you?

Convert a string to an array of 16bit unsigned integers

I have a string represented in hex format, how can I convert this to an array of 16 bit unsigned integers?
I know I can use string to byte array to easily convert it to 8 but unsigned integers, is there a simple way for 16 bit unsigned integers?
Solved!

While your description is somewhat vague and not very clear, I think the typecast solution from the previous poster may not be what you look for. You may more likely look for something along these lines:

Convert a string to an array of character

What would be the easiest way to convert a string "HELLO" to an array of character "H" "E" "L" "L" "O" ?
I have a way to do it with a for loop but I'm wondering if there is nothing even more simple.
Thanks in advance,
Martin

Try typecast instead.

Convert binary string into binary array

Dear I am looking for a way to convert my ten bit string array into 10 bit array.
Any idea?

Yes, but you need to tell us in more details what you have and what you want.
There is no "10bit string", they come in integer multiples of 8 bits. Some possible interpretations:
Maybe you have a 2 character string (16bits). Do you want the 10 low order bits?
Maybe you have a 10 character formatted string of zeroes and ones, one character for each bit.
Do you have a long string and every 10 consecutive bits are one 10bit number that you want as integer?
Please clarify!
There is no "10bit array". Do you want:
a boolean array with 10 elements, one element per bit?
An integer array if ones and zeroes?
An array of U16, each element corresponding to 10bits of the original string?
something else?
It might help if you could attach a small example containing typical data. (make current values default before saving and attaching here).

Convert HEX String into HEX Array

Hi!
Probably a silly question, but I am looking for a way to convert a ROM ID number such as "5E03C21000BA" into an short hexadecimal array.
The way to do this in C would probably be
char[17] str_romID = "5E03C21000BA";
uchar[8] romID;
sscanf(str_romID, "%02X%02X%02X%02X%02X%02X%02X%02X",
&romID[0], &romID[1], &romID[2], &romID[3],
&romID[4], &romID[5], &romID[6], &romID[7]);
but I can't seem to find a way to do this in LabVIEW. I would be very grateful if you could help me out with a sample program. Thanks ever so much!

Hello Blondchen,
I have attached a picture to my last explanation. This example doesn't take care of strings with an uneven number of chars!
My array has only 6 numbers as you only gave a string with 12 chars... That's what I asked before: how should we know where to split your string to the single numbers? Normally I would take 2 chars to form a byte (as I did in the example). If you give me 16 chars I give you 8 bytes...
I also think your C byte array will be an U8 array in LabView. If you REALLY need I8 numbers you can change the default type of the "hex to string" or cast to I8 (advanced->data manipulation->type cast) after the conversion.
Best regards,
GerdW

Is it possible to convert from string to variant?

Hi!
I would like to convert a text string to variant. I'm doing this because I would like to merge a couple of signals and then save all the signals in a lvm-file. Could someone please explain how to convert from text to variant, is it possible?
Thanks in advance!
Regards,
Mattias

What you are attempting to do is possible, but might not give you the results you expect. All you need to do is convert your string to an array of U8s using the String to Byte Array conversion primitive. In the file, you will get a single character per line of the file expressed as the ASCII code. When you read it, convert to U8s, then use Byte Array to String to get your string back.
You may also want to read up on LVM files. There are several places to put strings that work a little better than this.

Need help in converting string to numeric array

I am trying to convert a string to a numeric array ... the first # in the string gets cut off, the last three seem to come through.
This may be fairly simple, but I really haven't worked with the string functions all that much.
Help would be appreciated.

How to convert a string data to a 1 d array

Dear All,
I am wondering if somebody help me.
In the attached fle i have my program (in labview 8.6) which read temperature data and updates temperature during the time.
I want to use the updated temperature in a calculation. How can i get the new temperature which i think is in a string format and convert it to 1 d array?
I tried but the number that i got from temperature was not the same temperature which is shonw in data section of the program.
Could somebody please help me?

You are not reading temperature, you are reading a binary file. You seem to be assuming string format but do you really know? No one here can tell since you did not attach the file If it is you would need to use one of the string conversion functions. And please, get rid of the Data local variable. You are already usin shift registers. Do the same with the data from the file.

Which is lightweight array list or string tokenizer

which is lightweight array list or string tokenizer:
I am reading a flat file and doing some text parsing to find some records which matched my search criteria.
The flat file will have 5K records at the average and each records is in each line. (\n) is the delimiter to the string tokenizer.
My Doubt is:
Will it be good to manipulate all the records to the array list and then manipulating and achieve my task or
Will it be good if i do a just string tokenizer and achieve my task with out an arraylist.
Note: There is no unique fields in the records so no way to use hashmap/table.

However answering this a different way.
lightweight - your computer won't be heavier no matter which way you choose.
good - it will have no barring on your concious or your place in the after life.
good(2) - Write it the simplest way you think you can and worry about performance later if its a problem.

Converting a string of numbers into an array of booleans

For a homework assignment, I need to convert a string of numbers into an array of booleans. The string is a bunch of random numbers (0-9) in sequence, with no spaces. It looks something like this: 0123452348949230740329817438120947392147809231419. I need to make it so that each even number represents a "True" boolean and so that each odd number represents a "False" boolean. I think that I first need to convert each element of the string into a number, and then use a case structure (or something) to say, for each element of the array, "If even, then true. If odd, then false," but I could be wrong. Any suggestions?

I know you are trying to be vague but I'd like to give a key hint. Use the Quotient and Remainder function.
LOL maybe that was one of the objectives of the homework.
To be fair it sounds like there is more work that is needed. A new user of LabVIEW will have a hard time figuring out how to process each character one at a time when it isn't in an array.
It's just that most people (me at least) stopped thinking about division with quotient and remainder after basic algebra. I then of course changed my way of thinking when I used LabVIEW. Still most of the time when you use division you want to know the fractional part as a decimal. Thinking this way makes the problem more difficult then it needs to be.
