xmldecode

[Former Member]

Hi all,

In a transaction, the input is string. the string contains the encoded xml file.( The xml is xMII XML Format)

Now I want to decode the xml file and assign it to local property of xml type.

In the link editor, While evaluating the value it shows the xml file.While executing the transaction, it shows no error. But I could not get any output.

I have tried with the xml saver. It is not working.

Any inputs...???

Kishore,

I was experiencing a similar issue, so I wrote a custom action block.

See below for the code...

import com.lighthammer.xacute.actions.ActionReflectionBase;

import com.lighthammer.xacute.core.ILog;

import com.lighthammer.xacute.core.Transaction;

import com.lighthammer.xml.XMLDataType;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

public class TextToXml extends ActionReflectionBase

{

public TextToXml()

{

_texttoparse = "";

}

public String getTextToParse()

{

return _texttoparse;

}

public void setTextToParse(String s)

{

_texttoparse = s;

}

public XMLDataType getContent()

{

return _xmlcontent;

}

public void setContent(XMLDataType s)

{

_xmlcontent = s;

}

public String GetIconPath()

{

return "/com/companyx/xacute/actions/resources/icons/XMLParser.png";

}

public void Invoke(Transaction transaction, ILog ilog)

{

_xmlcontent = new XMLDataType();

try

{

String xmlContent = xmlDecode(_texttoparse);

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = domFactory.newDocumentBuilder();

Document doc = builder.parse(new org.xml.sax.InputSource(new java.io.StringReader(xmlContent)));

_xmlcontent = new XMLDataType(doc);

_success = true;

}

catch(Exception ex)

{

_success = false;

}

}

private String xmlDecode(String strIn)

{

strIn = stringReplace(strIn, "&", "&");

strIn = stringReplace(strIn, "&lt;", "<");

strIn = stringReplace(strIn, "&gt;", ">");

strIn = stringReplace(strIn, "&apos;", "'");

strIn = stringReplace(strIn, "&quot;", "\"");

return strIn;

}

private String stringReplace(String strSource, String strSearch, String strReplace)

{

StringBuffer sb = new StringBuffer();

int nLastPos = 0;

for(int nPos = strSource.indexOf(strSearch, nLastPos); nPos >= 0; nPos = strSource.indexOf(strSearch, nLastPos))

{

sb.append(strSource.substring(nLastPos, nPos));

sb.append(strReplace);

nLastPos = nPos + strSearch.length();

}

sb.append(strSource.substring(nLastPos, strSource.length()));

return sb.toString();

}

private String _texttoparse;

private XMLDataType _xmlcontent;

}

Hope this helps.

Hi Matt,

How this block is linked into BLS?

Where I can write the same code?

Guide me on this....

Namita,

The document i sent you is a generic 'how to guide' on creating action blocks.

The names of the classes and files in the document are my examples for the purpose of the document.

When writing the TextToXml action block, you need to use the string TextToXml whereever the MyAction string appears in the document. Including the name of the java file.

I would also suggest giving a meaningful name to the JAR file and replacing 'companyx' with your vendor name.

Hi Matthew Tuohy,

I am also looking for a help to create the custom action block, in xMII. It would be of great help if you share the document on " guide to create custom action block"

My e-mail ID: vishal.jadhav@tcs.com

Thanks for your time.

Hi Matthew..

I want to create CC: option while mailing in BLS (XMII 11.0).

Since there is no already built in option, i am trying to create a custom action block for it.

I just got the hint..it can be achieved via creating own custom block...

Can you help me in creating custom action block?

Any material/ idea/ link ... anything wld be of great help...

Thanking you in anticipation..

Hi, all.

A word of (strong) caution. Writing and adding custom action blocks is not something to be taken lightly. This code will run inside the BLS engine and can therefore cause significant problems if it is not written correctly.

This will be more "officially" supported with an SDK and deployment model in version 12.0, but I would not count on any official technical support for custom action blocks in 11.5. You'll have to depend on peer support here on SDN and you must accept all risk for any problems you might cause with your xMII installation.

Kishore,

I have written a white paper titled <b>Writing custom Action Blocks for xMII 11.5</b>

I cannot find a decent way to publish it in the forum...

I can email it to you if you wish?

Can you send me this document as well? bjhoffma@gmail.com

I am working on converting custom action blocks from version 11.0 to 11.5 and I'm most interested in where the files need to be place on the xMII server. Thanks!

Hi Kishore,

Could you please send the Transaction to my Email ID and let me have a look at it ?

[Former Member]

Hi Abesh,

<?xml version="1.0" encoding="UTF-8"?><Rowsets xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</Rowsets>

This xml is encoded as a string.

I am using an assignment action to assign it to local proerty of xml type.

The expression used in the assignment action is

Local.xml----> xmldecode(Transaction.string)

The output structure after decoding this xml looks like the same xml.

I hope this helps you.

Hi.

You should be able to change the transaction input to type "XML" and xMII will automatically parse it into an XML document.

- Rick

[Former Member]

Hi Rick,

If Input type is changed as xml type, the transaction can't be exposed as a web service. Thats why Input type is changed as string.

A string contains the encoded xml. By using xmldecode(String), it is converted into xml type. Now I have a xml. It has to be assigned to a xml type property. But it is not happening. Whenever the transaction is executed, it is not showing any error.

I hope this helps you to understand my problem in better way.

Hi all,

The problem here is, the output of xmldecode is in string type. when it is assigned to xml type, the transaction is not running.

The above method won't work.

The ultimate aim is

1. To get a string which contains the whole xml file.

2. Change it to xml type.

How this can be acheived?

any inputs appreciated.......

Kishore

I understand. The correct way to do this is with the StringToXml action, but there is a bug with this action that is not fixed until 11.5 SR3.

A workaround is to save the string content to a temporary file with the TextSaver action, load the same file using the XmlLoader action, and then delete the file with the DeleteFile action. This will work.

Also, you shouldn't need to xmldecode the string - this should automatically happen. Try it without the xmldecode (and the above technique) and see if it works.

Best regards,

Rick

Hi,

This solution works fine. But I have to save the file and delete it.

Is any other option there?

Regards,

[Former Member]

Hi, Kishore.

SAP xMII 11.5 SR3 should be available shortly, which includes a fix to the StringToXml action. This action is precisely what you need. You pass a string into the action, and an Xml object is the output.

Best regards,

Rick
