What is Web Scraping:

In simple terms, Web scraping, web harvesting, or web data extraction is an automated process of collecting large data(unstructured) from websites. The user can extract all the data on particular sites or the specific data as per the requirement. The data collected can be stored in a structured format for further analysis.

Steps involved in web scraping:

1. Find the URL of the webpage that you want to scrape
2. Select the particular elements by inspecting
3. Write the code to get the content of the selected elements
4. Store the data in the required format

It’s that simple

Was wondering if anyone had a simple way of calling  ##class(Ens.Director).EnableConfigItem() within a Business Process or adding code to a Custom Service to start or stop the object?

The use case is that I have a Process that uploads a file into a external SQL table. When it is finished I want it to kick off another Service that does the processing of the data that it just uploaded. Once it is finished the response is sent back to the service and when the service receives the response from the process, I want to stop that service from running.

so...

1. Service  A sends file to Process A to

Hi guys!

My student asked my why his unit tests don't work as they should, and I just could answer him. Here is the simplified case.

There is a class with a required unique property Name:

Class Test.NewClass [ Abstract ]
{
Property Name As%String [ Required ];
Index NameIndex On Name [ Unique ];
}

And there is an inherited class:

Class Test.NewClass1 Extends (%Persistent, Test.NewClass)
{
}

What I expect to happen, is when I save two objects of class Test.NewClass1 with the same value of property Name, for the second one to get an error stating that it violates the unique index.

When creating a PRA (Privileged Routine Application; which by the way is not relevant just for Routines but also for Classes/Methods), it is important to make sure you include a new $ROLES, before calling AddRoles(). For example:

new$ROLESset status=$System.Security.AddRoles("MyPrivilegedRoutineApplication")

This way you ensure that indeed the added (elevated) roles "evaporate" for the User running this code, once the User is out of the scope of that routine/method.

TL;DR: This article describes an introductory-level project that exercises some string-manipulation functions in both ObjectScript and Python…with specs from a song.

After you’ve written your first “Hello World!” program, are you ready for a new fun challenge?  An old, very popular (at the time) song may be just what you need.

While I was driving around on vacation in southern Maine, the local “Legends” radio station played the old classic, “The Name Game” by Shirley Ellis (https://www.youtube.com/watch?v=5MJLi5_dyn0). If the listener resists the urge to get up and dance and instead listens

Hi, how do I create a trigger that will only set the value of the "Status" field for new objects, not for all available?

Class CarDealer.Order Extends (%Persistent, %Populate)
{

 Property Title As %String

 Property Status As %String(VALUELIST = ",InProgress,Done,Canceled");

Trigger setStatus [ Event = INSERT, Foreach = row/object, Time = AFTER ]
{
 &sql(update CarDealer.Order set Status = 'InProgress')
}

Hi Developers!

Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?

Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.

When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.

So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!

Hi Community,

I need to convert HL7 Message into FHIR Format.Can anyone share basic reference for FHIR ADT^A01 message?

For converting HL7 message to FHIR we need to convert HL7 to SDA3 format and then converting SDA3 to FHIR format.

Please Share few basics steps for converting SDA3 to FHIR message?

Thanks

Hi,

I

want to get the values from a serial property because my code depends upon the class serial class.

For example

Serial class

Class Data.Serial Extends %SerialObject

{

Property FirstName as %String;

Property LastName as %String;

}

Persistent class

Class Data.Persistent Extends %Persistent

{

Property MPID as %Integer;

Property Name as Name.Serial;

}

Now i need save MPID and Name(Serial class property into SQL Table ) so i am trying the below class

Class Data.TestUtil Extends %RegisteredObject

{

Method Savedata(MPID,FirstName,LastName)

{

Set tSC=0

Set Obj=##Class(Data.

Hi,

when I using ObjectScript Trigger Code , I want to get whether the fields has changed by using "{fieldName*C}" ,  actually, fieldName in "{fieldName*C}" is a real field name ,but in my code, fieldName is a variable as follows:

SET stat=##class(%SYSTEM.SQL).GetColumns(tableName,.byname,.bynum,1)
		IF stat=1{
			SET i=1WHILE$d(bynum(i)){
				SET xColName=bynum(i)
				SET valComp={xColName*C}
				
				IF valComp=1{
					SET oldVal=1//{xColName*O}SET newVal=2//{xColName*N}
					&sql(INSERTINTO Yan.LogTableExt(Parref,ProperName,OldValue,NewValue) VALUES (:id,:xColN

Hi 

I have a  Zen Page with tablepane which has a datasource in a different namespace to that of the Zen Page. When the page is run, no data is returned and the tablepane is not populate,  even though the rerferenced table contains dat.

The tablePane code is as follows:

<tablePaneid="DataExtractionCurrent"showZebra="true"cellSpacing="2px"OnCreateResultSet="DataExtractionCurrent"></tablePane>

The OnCreateResultSet points to the following method:

Method DataExtractionCurrent(Output tSC As%Status, pInfo As%ZEN.Auxiliary.QueryInfo) As%ResultSet [ ZenMethod ]
{

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches. In short, loops iterating over $ListBuild lists with $ListNext or over a local array with $Order are the fastest options.

As a motivating example, we will consider looping over the pieces of a comma-delimited string.

A natural way to write such a loop, in minimal code, is:

For i=1:1:$Length(string

Your help is appreciated.

Hello all; I am using a one-to-many relationship.  I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id.  This seems upside down, and not what I expected.

Class Claim

{
    Relationship ClaimLineRel as ClaimLine [Cardinality = many, Inverse = Claim];
}

Class ClaimLine
{
    Relationship Claim as Claim [ Cardinality = one, Inverse = ClaimLineRel, OnDelete = cascade];
    Index ClaimIndex on Claim;
}

But the storage globals for Claim show data in the ClaimLine spot:

^ClaimD(1)=$lb("",$lb

A small reflection/question for today... it's true that new IRIS for Health (I4H) releases are more and more powerful each time regarding FHIR capabilities. Nowadays it allows us to consume FHIR resources with extrem easiness, we can connect with end-points in external FHIR servers very easily and make I4H act as passthrough or consume their resources... or, even more, we can define, configure and run a FHIR repository in, literally, less than 5 minutes.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

MSH| ^~\&|||||20221014103828.043+0100||ACK^A03^ACK|1049|D|2.5.1
MSA|AE|1665740278804

Hi ,

Still a newbie for ensemble, I am trying to convert XML message to HL7 Message. I am using Custom schema for XML structure which includes MSH and PID segments from HL7 Message.

These are the service, process, Operation classes i am using 

Business service-EnsLib.EDI.XML.Service.FileService

Business Process-EnsLib.MsgRouter.RoutingEngine

Business operation -EnsLib.HL7.Operation.FileOperation

I am using data transformation to convert XML message to HL7 message  and data transformation is working fine and im getting this in the business operation.

Good men don’t need rules.

Hi everyone,

I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.

I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.

ClassMethod getSportsPerDate(language As %String, date As %String){
