What is namespace in XML
What is the use of namespaces
How to create a namespace
XML Namespace examples
Prefixes can be used in XML to resolve elements name conflicts
When using prefixes in xml, a namespace for the prefix must be defined
xmlns:prefix="URI"
The namespace can be defined by an xmlns attribute in the start tag of an element
All child elements with the same prefix are associated with the same namespace
Namespaces can also be declared in the XML root element
Default Namespaces
Defining a default namespace for an element saves us from using prefixes in all the child elements
xmlns="namespace URI"
XML namespaces are used for providing uniquely named elements and attributes in an XML document

Thanks Raghav for ur video 👍,
What's the use of uri in namespace, and what that uri locates ?
Hi, The namespace URI is what allows us to identify uniquely the namespace stackoverflow.com/questions/18974378/what-does-namespace-uri-exactly-means
@@RaghavPal Do we always need a live url for identification of the namespace? or is there some other way?
Hi Raghav, brilliant explanation! Request you start a series on oracle osb 12c in detail. Theres hardly any good explanatory material available online for a beginner to understand osb and i think with your simple yet in-depth explanations can help many including me. regards!
Noted, will plan Divyajyoti
Hi Raghav, What are the valid values for URI? How to decide, values for URI?
Hi Sneha, URI is the Uniform Resource Identifier, like URL for a web page, it is the locator of a resource on the server, So it has a fixed value for every resource and you should get it from your dev or product team
@@RaghavPal Thanks Raghav for quick reply.
But, if I am creating a XML for myself and I need to give a unique and valid URI for namespace and if there is no dev or product team. How to choose it?
Thankyou so much from the land of mountains,Nepal
Most welcome Subash
Hello Raghav ! Excellent video with detailed explanation ! Request you to start a video on-"How to use xsi:type ="xsd:string"" in Soap request and response . Thank you so much ! OR do you already have a video done for that ?please let us know
Noted
Clear explanation. Thanks.
Glad it was helpful Hui
Please explain for what purpose of the URL is. Many thanks for this great series of videos.
Hi Steven, pls tell me the exact time stamp to refer
@@RaghavPal well many of the namespaces on your video are associated with URLs, but what i didn't understand is why would i associated an XML element to any URL?
@@daniel.balandra seems he doesn't have answer 😅
the URL used as a namespace identifier in XML is a convention to ensure global uniqueness and does not necessarily imply any direct web resource retrieval.
Thank you for this very useful video!
You're very welcome
Hi,
Thanks for the content.
What is the use of the URI in the NameSpace?
You can
@@RaghavPal I have the same question. What is that URI for> Which server is that pointing to?
Uniform resource identifier, it locates the resource where that particular operation can be executed using required parameters we give
@@basavaraju1466 this doesn't really answer the question. What needs to exist at the URL provided?
What is the purpose of adding the uri to the namespace? Documentation or does it validate something?
url allows to identify the namespace uniquely
Thank you! ❤
Most welcome Shane
Hi Raghav, does it requires to learn HTML and CSS for automation testing?!
No, it does not, but having knowledge of XML and JSON will help specially for API testing
HTML is basic, you must learn HTML,
atleast for 3 hours, make some basic web pages, do practice.
you can learn it from you tube.
Good luck.
Your video very helpful
Glad it was helpful Kanchanlata

I can only understand till prefixes. I have many questions..
1. Why would anyone combine a XML document(furniture) with a HTML document(Tables).
2. Please anyone give me a real example. Added to this, how can we join a HTML document with XML documents!
3. What is a real, physical meaning of namespace, do we have to provide namespace always while using prefixes?
4. Why at the first place I would want to initialize my tag to "URI" using a namespaces. ?
Please somebody answer this question....
Hi, I will plan to check on these, Meanwhile if anyone can help, pls add your *Comment*
Awesome! Thank you so much.

I don't get where the link or URI takes us to or what URI should we provide
In XML (eXtensible Markup Language), a Uniform Resource Identifier (URI) or link is used to identify or locate resources. A URI can be a Uniform Resource Locator (URL) or a Uniform Resource Name (URN).
Brilliant video! I do have a question, I happen to run into a problem when trying to write back into an xml after i changed somethin. The default namespaces get written in properly, but there have been local namespaces, which were not defined above inside an element which dissapeared. Can i just add them to the default definition?
Hi, It is possible to add local namespaces to the default definition in an XML document, but it depends on the specific structure and requirements of your XML document
When you add a namespace to the default definition, it is applied to the entire document, including all elements and attributes
This means that if you add a local namespace to the default definition, it will be applied to all elements and attributes in the document, even if they don't require it. This can lead to issues with validation and compatibility if the namespace is not used correctly
A better approach would be to keep the local namespaces separate from the default namespaces, and define them only on the specific elements and attributes that require them. To do this, you can use the xmlns attribute to define the namespace on the specific element or attribute
E.g.
It's also important to note that if you change an xml file, it's always a good practice to validate the xml file with the appropriate schema before sharing or publishing it
But how can we give the urls? Is there any criteria for this
Priya
When including URLs in XML documents, there are a few considerations to keep in mind. Let's explore how to handle URLs within XML:
1. Plain URLs:
You can directly include a URL within an XML element. For example:
```xml
¹(www.mysite.com/page?id=1)
```
However, if your URL contains special characters (such as `&`, ``), you need to escape them properly. For instance:
- `&` should be replaced with `&`
- `` should be replaced with `>`
2. CDATA Sections:
To avoid escaping special characters, you can use CDATA (Character Data) sections. Text inside a CDATA section is ignored by the XML parser. Here's an example:
```xml
```
In this case, the entire URL (including any special characters) is preserved as-is.
3. XLink (XML Linking Language):
If you want to create links within your XML document, you can use XLink. Here's a simple example:
```xml
Visit W3Schools
```
XLink allows you to define relationships between elements and external resources.
Remember that the choice between plain URLs, CDATA sections, or XLink depends on your specific use case and requirements. Choose the approach that best suits your XML structure and content.
Best👍

hi sir what is the URI that is used? does it have to point to an XSD?
Hi Diego, what is the context here, pls point the time in the video so I can refer
How do I add custom namespace uri and local part in soap response in java spring
Hi Krupa, I will need to check on this
Im highly confused on the addition of h: and f: 😢
ok, will try to add more details
what is the use of uri?
Anuj
URIs act like unique addresses for online resources, telling you where to find them and sometimes even describing them
what to write in URI of namespace?
The namespace declaration has the following syntax. xmlns:prefix="URI".
www.w3schools.com/xml/xml_namespaces.asp
IRI or URL? 2:04
its URI here

Muy bienvenido
You not provide the information where to use this language
In your videos you teach the how write the language but what is Output you are not showing.?!
Hi Adil, I created this playlist for people who work with XML like in API Testing etc, but need to know more about the basics. But I get your point, will add more videos
w3school ?
and several other resources, I tried to make it useful and understandable for beginners
hey this one is from w3 school
hope it helped, i studied diff resources including w3school
No !
you are not teaching from scrach.
