XML FunctionsBallerina supports various built-in functions to manipulate XML. |
|
import ballerina/io;
|
|
function main (string[] args) {
xml bookName = xml `<name>Book1</name>`;
xml bookComment = xml `<!--some comment-->`;
xml someText = xml `Hello, World!`;
xml content = someText + bookName + bookComment;
|
|
string xmlString = "<book/>";
xml book = <xml>xmlString;
|
Other than the XML literal syntax, XML can be parsed using a string. The string should be a valid XML. |
io:println(bookComment.getItemType());
|
Get the type of the XML element. |
io:println(bookName.getElementName());
|
Get the name of an XML element. |
io:println(bookName.getTextValue());
|
Get the text content of an XML element. |
io:println(content.isEmpty());
|
Check if the XML element is emtpy. |
io:println(content.isSingleton());
|
Check if the XML element has only one value. |
xml x = content.slice(2, 3);
io:println(x);
|
Get a subsequence of an XML sequence. |
x = content.elements();
io:println(x);
|
All the element-type items are taken from an XML sequence. |
x = content.select("name");
io:println(x);
|
An XML element with a particular name can be retrieved. |
book.setChildren(content);
io:println(book);
|
Set the children of an XML element. |
x = book.*;
io:println(x);
|
Get all the children of an XML element. |
x = book.selectChildren("name");
io:println(x);
|
Get a particular child of an XML element. |
x = content.strip();
io:println(x);
|
Remove any text items from an XML sequence that are all whitespace. |
x = bookComment.copy();
io:println(x);
}
|
Make a copy of an XML element. |
$ ballerina run xml-functions.bal
|

<name>Book1</name>
|
Selected child. |
Hello, World!<name>Book1</name><!--some comment-->
|
