Hai friends,
I am using filter node to validate my xml.. i am wring the validation conditions.
In one of the conditions i have to check whether the xml element is integer or not. can any body tell me how to check this condition in ESQL.
I appreciate if you tell me how to check the date forat whether the xml element containing the yyyy-mm-dd format value.
Thanks in advance

| Any reason why you are not using the validation facilities that are available in the MRM domain? |

I have to perform more validations on the element values
i thought it is the easiest way. instead of creating another message set project and using message defintion files i am using filter node to validate. |

So you want to write ESQL to do something which the MRM parser can do automatically...
I know the MRM parser can be difficult to set up ( that's why I monitor this forum ) but I am not convinced that you are taking the easiest road. Maybe you have some validation requirements that the MRM parser cannot handle? |

YES, i have to do some validations at the element value level, and i'm new to the message broker. i have somany confusions in using message set and mrm domains. thats the reason why i have choosen this way.
I am validating the values using esql..
my main problem is i need to check the one value whether it is integer or not.
and few more like checking date format(yyyy-mm-dd) and time stamp.(yyyy-mm-dd hh:mm:ss)
if you know these things please tell me. |

Hi bshankar,
Q1 : Which version of WMB are you using?
Q2 : Which XML domain are you using?
Q3 : Do you have an XML Schema available for your input XML?

Message sets are a core feature of message broker. They allow you so separate the definition of the message from the processing of the message. If you ignore and avoid message sets you will simply create a problem for the person who maintains your message flows. |

Hi Padawan
1. i am using wmb6.1
2. i am using xmlnsc domain
3. I am checking wether the input xml is well formed or not in input node itself
4. and i'm using filter node for validating the element values of the xml
5. I have xml schema also. but i'm not using it.
if possible please give me your contact details. |

Thanks for the details. Please read this:
http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/topic/com.ibm.etools.mft.doc/ad67020_.htm
...and make sure you read the topic about validation.
It would be very strange to do the validation in a Filter node when
a) you have the XML Schema
b) you can import the XML Schema to create your message definition file
c) XMLNSC supports validation

Sorry - I don't give out my email address online. I'm an IBM developer, and I work on the message broker parsers. You can contact me on this forum whenever you like. |

i tried out validating xml using message set with the domain mrm. but it is not validating properly it is sending the message to failure node eventhough i'm sending the valid xml.
i fed up with that method. so i started writing esql. |

The MRM domain does not support 100% of XML Schema. That is why v6.1 offers XML validation in the XMLNSC domain. Please switch to XMLNSC and try again.
If you hit a problem, just post the error message here. |

Kimbeart,
It is working fine with xmlnsc domain. but the thing is, it is not validating some validations like i have provided restriction tag in the xsd. in that i have metioned some values.It has to accept those values only. but it is accepting anything as a value..
I hope u understand my doubt.
thanks

Let me see whether I have understood that correctly.
- Your XSD contains a simple type with some enumeration facets.
- Your XSD contains an element or attribute based on that simple type.
- In your input XML, the element/attribute has a value which does not match one of the enumerations but you are not getting a validation exception
- You are getting validation errors for other types of bad input
Please post the XML Schema and the input XML.
- Use [code] tags to preserve the indentation and make it readable
- Cut it down if necessary. |
