XML document - request string

[Former Member]

Hi Experts,

Could you please tell me, how to pass XML document as a request string to the webservice scenario. Inside the service, I have to do the schema validation for the request . Please guide me, how to proceed further?

Regards

Sara

Hi Sara,

By request string you mean under one node every thing should come as a string then you have to use java mapping and there you can do xml Validation also.

Thanks

Yes, Sunil. What you have mentioned is correct. Could you please tell me, how to pass the XML document as a input string?

Sara,

Depending on how your XML document is "received" (inputsource ? DOM ? SAX ?) you will need to serialize it to a String object ...

It is easily feasible in a JAVA mapping, ie, in the execute() method of your mapping, read the inputsource object and collect each read byte into a String var and then use it to build your target document ...

In the aii_utilxi_misc.jar file, there is a class dedicated to string conversion : StringConversion that provides a lot of useful static methods, and one may interest you :

public static String xml2String(byte xmlBytes[]) {...}

It may be worth giving a try ?

Otherwise, please give us additional detail so we can help,

Rgds

Chris

See this

/people/michal.krawczyk2/blog/2005/11/01/xi-xml-node-into-a-string-with-graphical-mapping

U may also use java mapping and pass the whole input string with parsing to anu target node

Hello Sara,

how to pass the XML document as a input string?

you can change the XML message's tags into something else and later on chage it back .

you can also include the XML message inside a CDATA tag .

Take a look at this weblog: Frm Michal Krawczyk

XI: XML node into a string with graphical mapping?

Create the Data type that has only one data type that has type xsd:string

|||ly create message type corresponding to that

Instead of using graphical mapping use XSLT mapping that converts the whole XML doc into a single string out.

<?xml version='1.0' ?>

<xsl:stylesheet version="1.0" xmlns='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />

<xsl:template match="/">

</xsl:template>

</xsl:stylesheet>

use XSL:value-of select="node" in your element..

Thus create an xsl file and append it to winzip file. and copy it to imported Archives.

Hi SARA,

use following Code written in SAX parsing .this will fulfil your requirment.This handle Special character also.
