I have this XML data which basically to add/minus/multiply the two numbers. And I have this Xquery function that suppose to convert this XML data into a readable string format.
For example, let say XML file has in this form :
<expr>
<add>
<number>2</number>
<number>3</number>
</add>
</expr>
<expr>
<divide>
<number>7</number>
<times>
<number>1</number>
<number>6</number>
</times>
</divide>
</expr>
the Xquery function will be able to convert this into "2 + 3" and 7 / (1 * 6) respectively through the local:convertExpr function
Below is the sample of the Xquery that I am working right now :
Xquery File :
declare function local:convertExpr($expr) {
(: function to convert XML into a readable string format :)
let $number := data($expr[1])
let $x := $number
return $x
};
validate{<html>
<head>
<title>{/*/q:title/text()}</title>
<script type="text/javascript" src="miniformvalidator.js"/>
</head>
<body>
<h1>{/*/q:title/text()}</h1>
<form>
<ol>
{
let $exprs := /*/q:expr,
$count := count($exprs)
for $i in (1 to $count)
let $expr := $exprs[$i]
return <li>{local:convertExpr($expr)}</li>
}
</ol>
</form>
</body>
</html>}
I am able to pull all the numbers within the tags right now, but I am not sure how I can connect these numbers to become one readable string.
Please help. Thanks! :)
