copied!<p>I'm trying to sort some xml into different arrays and I'm a bit stuck on how to go about this.</p> <p>Here is the xml: <a href="http://pastebin.ca/1754892" rel="nofollow noreferrer">http://pastebin.ca/1754892</a></p> <p>I'm using this xpath expression to get every "series" element that contains at least one "item" child node.</p> <pre> var ceerez = theXML.evaluate( '//series[item]' ,theXML, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null ); </pre> <p>then I'm iterating over the result and putting the elements in a regular array:</p> <pre><code>var newArr=[]; for (var m = 0; m < ceerez.snapshotLength; m++){ newArr.push(ceerez.snapshotItem(m)); } </code></pre> <p>so what I would like to do next is to map and sort the elements in the newArr array into new arrays for each different sort. </p> <p>I want to have one array that is numerically sorted by the "pub" attribute (as numbers) for each series element.<br> One array that is sorted alphabetically for each "title" child element's text.<br> One array that is sorted by date for each "item" child element. </p> <p>I know how to do this with the sort() method, but I cant figure out how to do it from within the map() method so that I can make it into a new array. </p> <pre><code>var a2z1 = newArr.map(function(item){ item .sort(function(a,b) { return a.firstElementChild.textContent.toLowerCase().replace(/[^a-z,0-9]/gm, '') < b.firstElementChild.textContent.toLowerCase().replace(/[^a-z,0-9]/gm, '') ? -1 : 1; }); ); </code></pre> <p>(a.firstElementChild) would be the "title" element.</p>
