Intro

Recently I reread this article by @Bernd Mueller. It's about calling DELFATE function from zlib library. In this article I'll demonstrate several different approaches to callout libraries, we'll build the same functionality (compress function) in several different languages and compare them.

The following code walks a DOM using %XML.Node. It also prevents %XML.Writer to change whitespace. Run the code using the class method "test":

Class objectscript.walkDOM Extends %Persistent
{
    ClassMethod dfs(node As %XML.Node)
    {
        s entrynode=node.NodeId
        do {
        //element nodes with one whitespacetyped child are the ones we want to change
        if (node.NodeType=$$$xmlELEMENTNODE){
            s snode=node.NodeId     
            if (node.MoveToFirstChild())            
                {
                    i ('node.MoveToNextSibling()){
                        i (node.NodeType=$$$xmlWHITESPACENODE){
                            s node.NodeType=$$$xmlTEXTNODE
                            s node.NodeId=snode
                        }
                    }
            }
            s node.NodeId=snode     
        }   
        if (node.HasChildNodes()){
            d node.MoveToFirstChild()
            d ..dfs(node)
        }
        } while (node.NodeType'="" && node.MoveToNextSibling())
        s node.NodeId=entrynode
         
    }
     
    ClassMethod test()
    {
      set xml = "abcdefg"
     
      s reader=##class(%XML.Reader).%New()
      do reader.OpenString(xml)  
      set writer = ##class(%XML.Writer).%New()
      //do some magic
      d ..dfs(reader.Document)
       
      w !,"with indent=1:",!
      set writer.Indent = 1
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
      set writer.Indent = 0
      w !,"with indent=0:",!
      do writer.OutputToString()
      do writer.Document(reader.Document)
      w writer.GetXMLString()
    }
}

Here's a link to the code on GitHub: https://github.com/intersystems-community/code-snippets/blob/master/src/...

I am trying to use Entity Framework with Visual Studio 2017. After following the Intersystems documentation ("Using the Caché Entity Framework Provider") I still cannot see the data source in Server Explorer. Any ideas why?

I want to test automatically that HL7 business operation works correctly in error conditions. One is to test CE acknowledgement. I have planned to implement test production which includes business services for different situations (AA, AE, CA, CE, timeout, late response etc).

How should I implement HL7 business service that always returns CE (commit error)? I have tried but it keeps returning "AA".

This is the class which I want to test.

Class GSK.MyTestUnit Extends %RegisteredObject
{

ClassMethod Add(num1 As %Integer, num2 As %Integer)
{
s res=num1+num2
q res
}
}

This is my testing class.

Class GSK.TestingClass Extends %UnitTest.TestCase
{

Method test()
{
Do $$$AssertEquals(##class(GSK.MyTestUnit).Add(3,8),41, "Test Add(2,2)=4 passed ")
do $$$AssertNotEquals(##class(GSK.MyTestUnit).Add(3,8),11,"pass/fail")
}

}

Have a great weekend!

Hi,

I need to route a message synchronously to multiple targets using a routing rule.

In IRIS I built a general routing rule set, made up of a couple of rules. For one Rule in particular, and based on a common condition, I want to send the incoming message to 2 different targets. (no transformation is used)

I can select, in the single SEND action, multiple target names, or, I can create consecutive SEND actions, one after the other, each sending to their specific target.

Working on a proyect with :

Cache Object Script, Jquery and Bootstrap :

I have a big problem to do pagination with parameter, to query filter and registry limitation, but i find a solution using session and global:

Hi,

How Can I get sentiment analysis (positive or negative attribute) from a source or entity from iKnow REST API?

Is there a responsive way to detect a source code change without using a source control hook?

Update

I have my own custom unit test tool which has lots of extra functions that I find useful such as Asserting HL7 Transformers and REST targets.

I have a studio hook that will send an event signal to my test runner that will automatically re-run a specific test class or test suite, for which I have a test runner viewing page that updates with the results.

Hi,

I ran into the Issue https://hibernate.atlassian.net/browse/HHH-10620. The workaround described at https://community.intersystems.com/post/support-java-hibernate-5 worked for me. I'm using Hibernate Version 5.3.2.Final.

The following code provides information about software builds. Read the original description below for information about the different methods:

Hi all,

I have a FTP.Inbounding service that read a file and move it to a other folder when it is processed. The problem is that is not working fine in SFTP server.

The code is coppied from How to - Customize Ensemble Settings article.

Hi!

Is there any way to export a class package to xml file programmatically which will include all the classes of the package?
