In MB use LENGTH, In MQ use getMessageLength()
Is this what u wanted ?

Hi,
Is there a way to count the whole OutputRoot.XML tree rather den counting each child eg LENGTH(OutputRoot.XML.Message.a)? thanks |

You can use ASBITSTREAM to flatten the data into a bitstream (a BLOB) and then do length of that.
Otherwise, you can't really even get this by walking the tree - because you won't get tag names in your lengths.

Hi,
How do I calculate the data length for OutputRoot.MRM?
I tried using
SET Datalength = ASBITSTREAM(OutputRoot.MRM SET 'adf' TYPE 'fdfd' FORMAT 'CWF1');
Using this way, I only get the data length of the Custom Wired Format but not those MRM tags..
Thanks |

| ASBITSTREAM gives the BLOB form of the input. CWF does not contain the tags, tht is y u get the length of only the data... |

There is only one reliable way to find the length of an output message. The method is the same whatever the domain.
1. Serialialize the message using ASBITSTREAM and save the result in a BLOB.
2. Get the length of the BLOB using the LENGTH function.
For CWF, it might be possible to do it by walking the tree and adding up the lengths. That will work sometimes, but it depends on the trimming and padding options on the individual fields. So if you want your message flow to be independent of your message set, I don't recommend that approach. |

Hi,
My input message body is of CWF then in my flow I parse it to MRM and after parsing, I try the following codes:
1)SET OUTPUT_DATA = ASBITSTREAM(OutputRoot.MRM);
2)SET DATA_LENGTH = LENGTH(OUTPUT_DATA);
after my 1st statement, I got the error "Invalid Wire format retreived". Since the flow has logically convert the CWF message to MRM why I can't convert it to BITSTREAM.
I tried this
1)SET OUTPUT_DATA = ASBITSTREAM(OutputRoot.XML);
2)SET DATA_LENGTH = LENGTH(OUTPUT_DATA);
it works for XML..

So...how were you expecting the MRM parser to find the correct message set? Please search for ASBITSTREAM in this forum if you don't understand that question. |
