The challenge of day 5 is to calculate a password of 8 characters by finding the MD5 hash of the input and an increasing integer index.
The password is constructed by taking the 6th character of the first 8 hashes that start with 5 zeroes (in hex representation).

Recently I needed a classmethod that returns annotation value based on a name of a activity.

As doing it at runtime seemed inefficient, I wrote compile-time utility that iterates over all business process activities and generates relevant code.

This code could be used in a variety of situations when you need to iterate over business process activities, just add it as a secondary superclass to your BPL processes.

Hello,

First of all thanks for your time to read and reply,

We would need some help,

We have an ORM_O01 which has a NTE.3 with a Line Feed

Our Process converts the XML to ER7 using the ITB as follows:

set context.mensajeHL7 = ##class(ITB.HL7.Util.Convert).XMLToER7(hl7,.tSC,"2.5")

When we show the ER7 we observe:

INTE|1||Psa libre\X0A\ Indice psa

We have thought about the following solution, where mensajeXML is the XML representation of the ER7 shown:

First of all thanks for your help and time

We would need to find inside PID:3 which one meets the following condition:

PID 3.4.1 = "CAC" and PID 3.5 = "JHN"

We have been investigating how could we do it

We have achieved to get single fields in a call request as follows:

request.GetValueAt("ORCgrp(1).ORC:OrderingProvider(1).IDNumber")

##class(Ens.Util.Time).ConvertDateTime(request.GetValueAt("PID:DateTimeofBirth"),"%Y%m%d","%Y-%m-%d")

Hello,

First of all, thanks for your help, and time, reading this questions, and answering to this doubt.

We have the following use case: to convert a HL7 ER7 ORU_R01 v2.5 message, to a Ens.Request Message which represent it with a custom data structure (each segment is a group of Properties).

To be more precise, the target Ens.Request Message's structure looks like:

I've seen a few password change posts, but I wasn't 100% sure it was the same process, so I am asking here. We periodically have to change the passwords for a few Cache user accounts across several servers. Is there a process/script to change these passwords without having to go into the web portal on each server? Thanks so much, and I apologize if this was covered in some of the other articles that I've run across. Just looking for the best method.

Use %XML.Node to walk a DOM

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

    {
      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)

      set writer.Indent = 1

      set writer.Indent = 0
      w !,"with indent=0:",!

      do writer.Document(reader.Document)
      w writer.GetXMLString()
    }
