i have something like this
<ValueSet>
<value id="0">109.3</value>
<value id="1">110.6</value>
<value id="2">111.1</value>
<value id="3">111.5</value>
</ValueSet>
and i need the id of the node that has the maximum value, i need do this in javascript using Xpath.
i do this:
var path = "//ValueSet[not(value <= preceding-sibling::ValueSet/value) and " +
" not(value <= following-sibling::ValueSet/value)]";
var result = this.documentRoot.evaluate(path, this.documentRoot, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
alert("max:" + result.textContent);
but doesn't work, :(
