XML variables:

This language has special xml variable which help with operations on xml.

Declaration

Unfortunetly xml variables need to be declared, we cannot use them with auto declaration, so everytime we want to use them we need to declare. Below is example.

xml Root;

Tag name

by default tag name will be the same as variable name, so our example declaration will create xml document with tag "Root"

xml Root; 
console(string(Root));

We should see xml document like this:

<Root></Root>

If we don't want to have the same tag name as variable name we can set or get tag name by using propertie "name"

Geting tag name:

xml Root; 
tagname = Root:name();
console(tagname);

We should see xml document like this:

Root

Seting tag name:

xml Root; 
Root:name("Document");
console(string(Root));

We should see xml document like this:

<Document></Document>

Basic operations (static)

We can easy do basic et/get operation on all tag values in xml document. Below few examples with decriptions.

Setting attribute

Source:

xml Root; 
Root:lang = "English";
console(string(Root));

Output:

<Root lang="English"></Root>

Setting child tag

Source:

xml Root; 
Root.Store = "List of books";
console(string(Root));

Output:

<Root>
  <Store>List of books</Store>
</Root>

Setting child tag attribute

Source:

xml Root; 
Root.Store.Book:name = "Moby Dick";
console(string(Root));

Output:

<Root>
  <Store>
    <Book name="Moby Dick"></Book>
  </Store>
</Root>

Setting tags and attributes

Source:

xml Root; 
Root.Store.Book:name = "Moby Dick";
Root.Store.Book:author = "Herman Melville";
Root.Store.Book.Description = "Not availabe yet";
console(string(Root));

Output:

<Root>
  <Store>
    <Book name="Moby Dick" author="Herman Melville">
      <Description>Not availabe yet</Description>
    </Book>
  </Store>
</Root>

Getting tags and attributes

Source:

xml Root = xml("<Root>
  <Store>
    <Book name="Moby Dick" author="Herman Melville">
      <Description>Not availabe yet</Description>
    </Book>
  </Store>
</Root>"); 

console(Root.Store.Book:name);
console(Root.Store.Book.Description);

Output:

Moby Dick
Not availabe yet

Setting Multiple tags with same name

Source:

xml Root;

Root.Store.Book[0]:name = "Moby Dick";
Root.Store.Book[0]:author = "Herman Melville";
Root.Store.Book[0].Description = "Not availabe yet";

Root.Store.Book[1]:name = "The Odyssey";
Root.Store.Book[1]:author = "Homer";
Root.Store.Book[1].Description = "Not availabe yet";

Root.Store.Book[2]:name = "Catch-22";
Root.Store.Book[2]:author = "Joseph Heller";
Root.Store.Book[2].Description = "Not availabe yet";

console(string(Root))

Output:

<Root>
  <Store>
    <Book name="Moby Dick" author="Herman Melville">
      <Description>Not availabe yet</Description>
    </Book>
    <Book name="The Odyssey" author="Homer">
      <Description>Not availabe yet</Description>
    </Book>
    <Book name="Catch-22" author="Joseph Heller">
      <Description>Not availabe yet</Description>
    </Book>
  </Store>
</Root>

Getting Multiple tags with same name

Source:

xml Root = xml("<Root>
  <Store>
    <Book name="Moby Dick" author="Herman Melville">
      <Description>Not availabe yet</Description>
    </Book>
    <Book name="The Odyssey" author="Homer">
      <Description>Not availabe yet</Description>
    </Book>
    <Book name="Catch-22" author="Joseph Heller">
      <Description>Not availabe yet</Description>
    </Book>
  </Store>
</Root>"); 

console("Books: " + string(Root.Store.Book:count1()))
console(Root.Store.Book[0]:name);
console(Root.Store.Book[1]:name);
console(Root.Store.Book[2]:name);

Output:

Books: 3
Moby Dick
The Odyssey
Catch-22
