Hello,
I need to read a message from an input queue ,extract the cdata from the message and sftp the file to the server.
My code currently sftp the file successfully to the server but cannot extract the cdata.It appends the whole message to the file.

what is going wrong when you try to extract the cdata section? Have you tried to debug your own efforts? Are you using ESQL or another coding method?
You may get more help if you post your code here and demonstrate that you have searched the documentation and forum for information. |

Hello,
Yes I am using esql and as a example this is input message
<IBIS version="2.0"><SH><SID>test</SID><TO></TO><FM></FM><MG>N</MG><MS>1</MS><LG>Y</LG><IT>2012-10-15 10:42:13</IT><OT>2012-10-15 10:42:14</OT><PR>1</PR><GID/><C3ID/></SH><AD><![CDATA[100000666 200905251042TC 20090525 000001000001000000174534KPN ENTERCOM MANAGEMLEIDSCHENDAM ]]><AH><TO/><FM/><DP/><MK/><RF/></AH></AD></IBIS>
expected output message is extracted the cdata only:
100000666 200905251042TC 20090525 000001000001000000174534KPN ENTERCOM MANAGEMLEIDSCHENDAM
written to a text file.
The code is simple :
SET outfile = 'workfile.txt';
-- Ensure the properties header is copied for CCSID and encoding
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot = InputRoot.XMLNSC.IBIS.AD;
SET OutputLocalEnvironment.Destination.File.Name = outfile;
Currently this is the output message:
<IBIS version="2.0"><SH><SID>test</SID><TO></TO><FM></FM><MG>N</MG><MS>1</MS><LG>Y</LG><IT>2012-10-15 10:42:13</IT><OT>2012-10-15 10:42:14</OT><PR>1</PR><GID/><C3ID/></SH><AD><![CDATA[100000666 200905251042TC 20090525 000001000001000000174534KPN ENTERCOM MANAGEMLEIDSCHENDAM ]]><AH><TO/><FM/><DP/><MK/><RF/></AH></AD></IBIS> |

Hi,
You should perhaps investigate if following line does what you think it does

| SET OutputRoot = InputRoot.XMLNSC.IBIS.AD; |

you are not extracting the CDATA portion correctly.
check your code and also check other flows that are similar where a CDATA section is extraced

I have not set it to SET OutputRoot.BLOB.BLOB = CAST(InputRoot.XMLNSC.IBIS.AD.(XMLNSC.CDataValue) AS BLOB CCSID 1208);
but getting error : The following error messages will give specific details of the location and nature of the error. Check and correct the syntax of the SQL statements and redeploy.
BIP2401E: (.test_Compute.Main, 19.84) : Syntax error : expected 'AS' but found 'keyword Blob'.
The expected token was not found.
Correct the syntax of your ESQL expression in node '.test.Main', around line and column '19.84', then redeploy the message flow. |

 set it like this
DECLARE chrCDataVal CHAR InputRoot.XMLNSC.IBIS.AD.(XMLNSC.CDataValue);
SET OutputRoot.BLOB.BLOB = CAST(chrCDataVal as BLOB CCSID 1208);
works fine now..thank you again for the help ..now cdata is appending to the file..only issue is how to include newlinefeed after each message |

You are hard coding the Window form of line separator (CRLF), what happens if you send the file to a Unix server in the future?
Either way don't forget to use a configurable service for the FTP definitions, it will avoid a code change if the server moves or credentials change. |

If the OP has the ftp operation set up as a text transfer, wont the FTP operation deal with that conversion for them? Or will that only do char set conversions? |

You should aim to make all WMQ and WMB implementations platform independent as a best practice.
Making the line end characters a UDP might be a good idea, then it could be changed without a code change.
FTP should convert the file line terminators, but SFTP should really be used and that only does binary. |
