Parsing An XML Data With DOM Parser In Apex

Parsing the XML data in Apex is always pain and there are already very good blogs and links that really help us to design the strategy for parsing XML data of various complexities .

The above blog from Abhinav one of our MVP of sfdc dev commmunity is informational and i suggest everyone to read this on how to use fast XML DOM.

There is a cookbook article as well on how to effectively achieve the parsing of XML using DOM parsers

One has to know two system classes a)Document Class b)XMLNode Class

Now the question then ,why I am I writing this blog when already there are so much information on web as how to do it.The reason is even after reading all the documents in net ,i struggled to parse an XML as none of the blogs speak on how to parse when we have namespace in the XML.

Here is the sample XML data that i am trying to parse
Now one thing you will observe in the below parser code that i have written ,how i use the namespaces to parse the data.Providing namespace as null will trigger null pointer exceptions

So the idea of this blogpost was just to make one aware on how to parse the XML if there are namespaces .

Hope you enjoyed the blog series .

Invoking Apex Callout From Process Builder

Process builder is GA in Spring 15 and one of the queries I came across was around how to invoke apex callouts from Process builder .

Before process builder came we had two common approaches of calling webservice 

1)We have outbound messages as one of the Actions for workflows.This works if other party implements the WSDL that is generated once Outbound messaging is defined with appropriate end point .

2)Most of times future method invoked through triggers allowed to do apex callouts and invoke external web service provided the future method is annotated with @future(callout=true).This provides lot of flexibility and one of the best approaches .

3)Flow triggers was in BETA and this was also one of the ways we could invoke callouts provided the Flow implements process plugin .To understand in detail how to implement process plugin refer to the below example

The purpose of this blogpost is to demonstrate the new possibility of invoking apex callout through Process Builder

Opening Modal Using Lightning Component Framework of SFDC

One of my friend from India threw a challenge .The challenge was to open a modal by using latest and greatest lightning components framework and modals design from SLDS .For the love of community I thought of sharing the entire code base that I did .

So here we start ..

Business Use Case - Need a handy SalesLeader board component that can be used to display the Sales revenue generated by each sales rep for current year in the order of decreasing total revenue .On click of the tile ,we will show detail opportunity list aggregating the revenue .

The component can be dragged in lightning design experience or in App builder lightning Page .

Writing Test Classes For Apex Rest Service

I came across a question in a developer community on how to write Unit Test Classes for the Rest API service for POST HTTP calls

Unit Test Classes for REST API following link is very useful and inspired by this jeff had an article on his blog on how to write the test method for same .

Here is the Jeff Blog Link Test Class for REST API(Good reference for GET Rest Services)

In one of my previous blog post i demonstrated how to use native parsing technique for Rest api for User Defined Type
I wrote the Test class for the same and this post is helpful for all those searching for how to write test classes for apex rest service annotated with POST Call
Here is the Rest Service Class for which i attempted the test class
