Generate Xml file in class

Generating XML file in Salesforce…………………………..

Ø  We need start class with global keyword

Ø  XmlStreamWriter Class

The XmlStreamWriter class provides methods for writing XML data.

For more information:

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_xml_XmlStream_writer.htm

class:

@Restresource(urlmapping = '/accounts/*')

Global class GenerateaccountXML {

   

    webservice static string generatexml(){

        xmlstreamwriter x = new xmlstreamwriter();

        list<account> acc = [SELECT AccountNumber,AccountSource,BillingCity,BillingCountry,DOB__c,Email__c,Name,

            (select name from contacts) FROM Account];

        string xmlstr = '';

        x.writeStartElement(null, 'Accounts', null);

        for(account a : acc){

            if(a.contacts.size()>0){

        x.writeStartElement(null, 'Account', null);

        x.writeCharacters(a.name);

        x.writeEndElement();

        x.writeStartElement(null, 'Accountbillingcity', null);

            if(a.BillingCity == null){

        x.writeCharacters('hyderabad');

            }else{

        x.writecharacters(a.BillingCity);

            }

        x.writeEndElement();

            x.writeStartElement(null, 'contacts', null);

            for(contact c : a.contacts){

                 x.writeStartElement(null, 'contactname', null);

                                     x.writeCharacters(c.name);

                                     x.writeEndElement();            

               

            }

            x.writeEndElement();

            }

        }

        x.writeEndElement();

        xmlstr = x.getXmlString();

        return xmlstr;       

    }

}

Execute following code in console :

string s = GenerateaccountXML.generatexml();

system.debug('account xml file is : ' +s);

Trigger on task object by using messaging class

Require ment:
 
/* whenever task is completed we need send
confirmation mail to related account....

*/

Trigger Send_Email on Task (after insert,after update) {

list<account> acc;

for(Task tsk : Trigger.New)
{

if(tsk.status == 'completed'){

acc = [select name,email__C from account where id =: tsk.whatid];
}
}
for(account a :acc){
if(a.email__c != null){

string mal = a.email__C;
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
String[] toAddresses = new String[] {mal};
mail.setToAddresses(toAddresses);  
mail.setSubject('A task owned by you has been updated');  
String body = 'Dear ' + a.name + ', ';
        body += 'I am informing about your task .';
        body += 'I am varaprasad CEO of salesforce.';
        body += 'your task is completed succesfully.. ';
       
mail.setHtmlBody(body);

Messaging.SendEmail(new Messaging.SingleEmailMessage[] {mail});


}
}
}

Email services in salesforce

Email services are automated processes that use Apex classes to process the contents, headers, and attachments of inbound email. For example, you can create an email service that automatically creates contact records based on contact information in messages.

Basic Synatx:

Before creating email services, create Apex classes that implement the Messaging.InboundEmailHandler interface.

global class myHandler implements Messaging.InboundEmailHandler { global Messaging.InboundEmailResult handleInboundEmail( Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) { Messaging.InboundEmailResult result = new Messaging.InboundEmailresult(); return result; } } Examples: example 1: global class createcontact implements Messaging.InboundEmailHandler { global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) { Messaging.InboundEmailResult result = new Messaging.InboundEmailresult(); Contact contact = new Contact(); contact.FirstName = email.fromname.substring(0,email.fromname.indexOf(' ')); contact.LastName = email.subject; contact.Email = envelope.fromAddress; contact.LeadSource = 'other'; insert contact; System.debug('====> Created contact '+contact.Id); return result; } } ---------------------------------------------------------------- example 2: global class createevent1 implements Messaging.InboundEmailHandler { global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) { Messaging.InboundEmailResult result = new Messaging.InboundEmailresult(); event e = new event(); e.Ownerid='00590000002dteE'; e.Subject = 'email'; e.StartDateTime = system.Now(); e.EndDateTime = system.Now()+1; insert e; System.debug('====> Created event '+e.Id); return result; } }
