Clash Royale CLAN TAG

undefined function 'xmls:getString'

I am trying to run a small program with ballerina. Here's my code.

import ballerina.lang.system;
import ballerina.lang.xmls;
function main(string args) {
system:println("Hello, World!");
string xmlvar = "<bookstore>n<book category="cooking">n <title lang="en">Everyday Italian</title>n <author>Giada De Laurentiis</author>n <year>2005</year>n <price>30.00</price>n</book>n<bookstore>";
string var1 = xmls:getString(xmlvar, "/bookstore/book[1]");
system:println(var1);

}

I have already imported ballerina.lang.xmls.

Any idea ?

getString(xml msg, string xPath)

Please try the following.

import ballerina.lang.system;
import ballerina.lang.xmls;

function main(string args) {

xml payload = `<bookstore><book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price></book></bookstore>`;

system:println(xmls:getString(payload, "/bookstore/book[1]"));
}


Also correct your end tag to </bookstore>

</bookstore>

Please refer documentation for more information.
