Hi,
Please let me know how to do URL encoding or HTML encoding in WMB.
I know we can do this in Java ( for URL encoding java.net.URLEncoder.encode), Is there any built in CCSID or any other way to do the encoding.
For HTML encoding I need to convert
| Code: |
<?xml version="1.0" encoding="UTF-8"?>
to
<?xml version="1.0" encoding="UTF-8"?> |

Forgive me for asking, but WHY are you wanting to do this?
What you seem to be wanting to do (By your example) is just to 'escape' the XML.
I'm sure Kimbert (or someone just as expert) will be along soon to help

We have an legacy application where we need to send the Whole XML document as an HTML encoded string. |

No - your best bet is to call a Java method from ESQL, or do the job in a JavaCompute node.
btw, that's a really strange use of the term 'CCSID'. Are you sure you meant that? |

And there I thought that just assigning the unescaped XML string to an XML element in the tree would give you the escaped XML as a result...
Of course going with a CDATA type element would make more sense...

Can you explain a little more about what you expect the output message to look like. You mention "java.net.URLEncoder.encode" but then posted an example that did not use this encoding as the java URLEncoder will give a "%xx" encoding, not "<" etc. Also what node are you sending this data out of? Are you actually making an HTTPRequest and want to send the data as part of a querystring or the body?
Kind regards,

mgk's question is an important one. I was answering the question about URL encoding ( based on the class name that Amitha quoted).

Yes, if basic XML escaping is what is required, then it will happen automatically.
Amitha: it would probably help if you could explain exactly what kind of escaping you want, and why. There are various ways of encoding a snippet of XML within another XML document. |

Thanks for the replies.
Actually I have two different requirements, 1) URL encoding 2) HTML encoding.
My apologies to include just one example.
| Code: |
Requirement 1:
WMB will have to send an HTTP POST request with data being URL encoded:
Content-type: application/x-www-form-urlencoded
Content-Length: 8484
method=<methodname>
data=<%3C%3Fxml+version%3D%221.0%22%3F%3E%0A>
Requirement2:
WMB will receive an SOAP request with XML message as HTML escaped string in the body and will have to return response in the same format.
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:getmethod xmlns:ns1="namespace " SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<inputXML xsi:type="xsd:string"><?xml version="1.0" encoding="UTF-8"?><?xml version="1.0" encoding="UTF-8"?><request>message <request></inputXML>
</ns1:getmethod>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
we need to parse the HTML escaped XML string embedded in the SOAP.

For URL encoding(Requirment 1) I can make use of the java method I mentioned.
But for HTML escaping(Requiement 2), I am using esql REPLACE method to replace the escape characters and then parse using CREATE statement.

I was thinking we can make use of CAST with CCSID for URL encoding(ISO-8859-1). As per infocentre ISO-8859-1 aliases to 819, but when I casted the string with this ccsid it didn't encode the characters. |

Have you actually checked the contents of the message tree before running your ESQL decoding algorithm ( using Trace node / debugger)?
All XML parsers automatically decode character refs like < and >. XMLNSC certainly does, and so you should get a CHARACTER field in the message tree which contains decoded XML.

You are getting confused between character encodings ( i.e. code pages / ccsids ) and escaping mechanisms like URL encoding. It is probably worth spending some time to learn the difference - otherwise you are going to have a difficult time as an integration developer  |

Hi Kimbert,
Thank you for suggestion. I figured out that XMLNSC parser does decode escape characters automatically.
But, for URL encoding there is no other way than Java. |

Yes (AFAIK), you have to use Java method java.net.URLEncoder.encode(String,'UTF-8') for URL Encoding but for this you have to use JCN instead of Compute Node as you cannot call this method from ESQL since this method contains a THROWS clause. There is another method java.net.URLEncoder.encode(String) for the same without throws clause but this one is deprecated. |
