you should look at XSLT, it can help transform xml as you need

ClassMethod SplitXML() 
{

    for item="market","product" {
        set params("path")="/doc/"_item
        
        Set tSource=##class(%Dictionary.CompiledXData).%OpenId(..%ClassName(1)_"||XML").Data
        
        Set tXSL=##class(%Dictionary.CompiledXData).%OpenId(..%ClassName(1)_"||XSL").Data

        // Transform the source according to the XSL
        Set tSC=##class(%XML.XSLT.Transformer).TransformStream(tSource,tXSL,.tOutput,,.params)
        If $$$ISERR(tSC) Quit
        
        write !!
        // Output the result to the screen
        Set tSC=tOutput.OutputToDevice()
    }
}

XData XML
{
<?xml version="1.0"?>
<doc>
<header></header>
<product><test>1</test></product>
<market><test2>2</test2></market>
</doc>
}

XData XSL
{
<?xml version="1.0"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:param name="path"></xsl:param>

<xsl:output method="xml" indent="no"/>
 
<xsl:template match="/">
    <xsl:copy-of select="$path"/>
</xsl:template>
    
</xsl:stylesheet>
}

will output like below

USER>d ##class(Test).SplitXML()


<?xml version="1.0" encoding="UTF-8"?><market><test2>2</test2></market>

<?xml version="1.0" encoding="UTF-8"?><product><test>1</test></product>

you can do it with ccontrol tool

Syntax:
    ccontrol create <instance name> <parameters>
Description:
    Create an instance's entry in the Cache registry.
Parameters:
    directory=<installation directory name>
    versionid=<version identifier>
Example:
    ccontrol create mystuff directory=/usr/cachesys versionid=2008.2.0.357.0

Looks like you forgot to define web application for your REST Service.  Please look at the documentation. And at this part:

Each subclass that has its own entry point must have its own CSP web application. You define the CSP web application and specify its security for on the Management Portal’s [Home] > [Security Management] > [Web Application] page, which you can access by clicking System AdministrationSecurityApplications, and Web Applications. When you define the CSP web application, you set the Dispatch Class to the name of the custom subclass of %CSP.REST and specify the first part of the URL for the REST call as the name of the application.

$case is used to convert one value to another. Like, you have some code, but you need a display text for it, you can do so:

set display=$case(gender,"F":"Female","M","Male",:"Unknown")

$select returns value when meets the first true condition. It needs if can't compare only one variable, or you have some more conditions.

write $SELECT(0=$ISVALIDNUM(x):"not a number",x=0:"zero",""=$NUMBER(x,"I"):"not an integer",x#2=1:"odd",1:"even")

Hi Greg, 

It is a very interesting question. I can't give you all that you want, but I'll try to give some hints. 

Deploy Script

In first, you are looking for some script. While you have to execute some script from Operation System, you have different ways how to do it. And here again, depends on what are you going to inside Caché. As you working on some Linux system, I'll start from it.

Linux:

To start some script inside of Caché you may use csession tool, in two ways: 

  • specify some routine or class, which will be executed at once, and after finish, that code csession will exit. In this case, you have to use some internal code, which already ships by InterSystems, or you can install some of your code.
    csession ENSEMBLE -UUSER ##CLASS(package.class).method()
  • or you can write some COS code, generated in your script, or just in a text file near to script. And send this code to csession. 
    csession ENSEMBLE -UUSER < deploy.mac

Windows:

On a Windows system, you don't have csession tool. But here available another tool cterm.

  • you can also specify routine name
    cterm /console=cn_ap:ENSEMBLE[USER]:^%D
  • but cterm also support special scripts format, which supports even interactive mode.

For both Windows and Linux also possible to launch executable file cache, and call your code in almost the same way as it does csession.

Deploy

To launch that script, you can use any of Continuous Integration system, which you like. I would recommend Jenkins, it is an opensource project, has lots of plugins, and supports multi servers installation. You can configure to launch your script, just by timetable, every time. Or check if appeared some new commits in your chosen System of control version (Subversion or so on), since it was run last time. Multi-server version may help have some different servers with a secondary installation of Jenkins, and control all of them from the master node.

Last time I found GitLab for myself, it quite good git server, with CI service inside. Supports multiple runners for CI, and you can choose which runner should execute some stages. You can easily configure multiple tasks which will be run after every commit. Like build, test and deploy if everything is OK.

Good choice, I'm already using gitlab in our company, with closed sources. In our process, I even deploy to our own windows server. Our application on Angular 2.

it is our gitlab-ci.yml, I've removed deploy stage.

Counts only lines which appear in the final "INT" code.  If you working with MAC code, you may open INT by pressing Ctrl+Shift+V in the Studio. And then you can go to this needed line wit dialog called by Ctrl+Shift+G, Where you should put 'label+line' or just '+line'. If you Studio says, that no other sources, you should check flag "Keep Generated Source Code" and add compiler flag "k" in the Studio options and recompile your routine.
