Thanks Kimbert . I have been able to perform Binary to Decimal conversion with ESQL . However , As you pointed out , it is in-efficient , I would be intrested to achive the same results using DFDL. I am sharing with you the DFDL Schema's being used. Please let me know which all attributes in these scema needs to be corrected.

A couple of points I noticed immediately:
- You are not setting the DFDL encoding property, so you are inheriting the value 'UTF-8' from the IBM default format block. I suspect that this is incorrect. What character encoding does the BUFR standard use?
- Most of your strings ( but not all of them ) are using lengthUnits='bytes'. That's usually a mistake, although there are edge cases where it is useful. Did you intend to do this?
- You are setting textStandardBase in the default format block but not on the binary elements. That's not the way I would do it - I would prefer to put an unusual setting like this on the element or on its simple type.

See the comments above. I have no idea why it is not working, and I certainly don't have time to try it out. The way this forum works is as follows:
- you try something
- if it doesn't work, you try to find out why
- if you get stuck, you tell us what you tried, and what happened
Does it work in the DFDL test utility in the WMB toolkit. Have you looked at the DFDL Trace to diagnose what's happening?
- we reserve the right to withhold help unless you do your bit  |

Encoding UTF-8 is correct as it has backward coimpatibility to binary codes ITA2 and ITA5.

I have not found any difference by setting either of the two i.e byte or character.

It is because textStandardBase is not appearing in my defined DFDL model.

Yes , here is the trace of one element.

OK - I see where you're coming from.
UTF-8 is an encoding of the entire Unicode character set. The first 128 code points are the same as ITA5 / ASCII. After that, UTF-8 becomes a multi-byte encoding, with the number of bytes for a character depending on the ms bits of the first byte. So it is true that UTF-8 is backward compatible with ASCII, but you still should not be using UTF-8 ( multibyte ) when you mean US-ASCII ( single-byte) or some variant thereof.
| Quote: |

It will work either way, unless and until your data includes a character with the top bit set. At that point, instead of getting an error telling you that you have a malformed character in your input, you might find that the data parses successfully with a funny-looking character included in the output. Or you might get a much less helpful error because the parser stayed on its feet far longer than it should have done.
In your case, the worst-case scenario might not be too bad, but I shudder to think how many hours have been wasted because developers fail to distinguish between ASCII and UTF-8. I wouldn't risk it.

Not your fault - this is a known usability problem with the DFDL editor. There are many DFDL properties, and some of them are so rarely used that you need to click the 'Show Advanced' button to make them visible. This property is one of those.
| Quote: |
| here is the trace of one element... |
The trace shows that you have extracted a string value from the input data, but it does not show the integer value that it was converted into. Please can you check in the trace - it should be showing the conversion.
If you cannot see the value in the trace then please look in the DFDL Infoset view - the converted value will be shown there. |

Thanks Kimabart , DFDL works ! Binary to Decimal works but Binary to ASCII got struck in DFDL.For type string it seems it is not performing conversion to ASCII and is printing the input. Any pointer please I tried with different type settings.

kimbert, not that it matters.
I knew that

You mean, binary represented as text can now be parsed successfully? What did you change to make it work?
| Quote: |

Not sure what that means. Please can you show us
- the input,
- the schema
- the resulting value in the infoset and
- (important) the relevant part of the DFDL trace.

It is kind of difficult to answer that. You have not described the problem, and you have not told us what these 'different type settings' were. Supply the information requested above, and I should be able to help. |

OK - I have some good news and some bad news for you. First the bad news:
a) your format is extremely unusual. I have never before seen a data format that uses one character per *bit*. I would love to meet the person who thought that this was a good idea.
b) DFDL can just about handle integers that are represented in this way, but it cannot handle character data in this ( very inefficient ) representation.
The good news: You can work around the problem as follows:
1. Change the domain on your input node to 'BLOB'.
2. Wire the input node to a Compute node
3. In the Compute node, convert the bit string to a BLOB using ESQL's CAST function ( I think you already know how to do that )
4. Convert the BLOB to CHARACTER using CAST. Make sure that you specify the CCSID correctly on the CAST.
5. Use an ESQL statement something like this:
| Code: |
| CREATE LASTCHILD OF <someplace> DOMAIN 'DFDL' .... |
...to parse the ( much more normal ) stream of bytes using the DFDL parser.
Before testing 5. you will need to adjust your DFDL model to work with bytes instead of bits. That will involve quite a lot of changes, because most of your data will now be binary and not text, and will be composed of bytes and not characters. I recommend that you create a new model, and test it in the DFDL Test perspective before attempting to use it in a message flow.
Good luck! |

| Or alternatively, ask the sender to send the original bytes, and not the expanded character representation. But that assumes that you have some influence over the incoming data format. |

Is't the below representation effecient and are actualy the original bytes. What is now required is reading 01000010 into B ( character representation in UTF-8 encoding for this byte ) .
01000010 - B
01010101 - U
01000110 - F
01010010 - R |
