Sorting Elements based on Attribute Value in Java -

-

I am trying to sort the node in the nodelist based on the item id. Looks like XML 

  & lt; Order & gt; & Lt; Lines & gt; & Lt; Line line not = "1" & gt; & Lt; Item ID = "Item 1" /> & Lt; / Line & gt; & Lt; Line Line = "2" & gt; & Lt; Item ID = "Item A4" /> & Lt; / Line & gt; & Lt; Line Line = "3" & gt; & Lt; Item ID = "ItemA7" /> & Lt; / Line & gt; & Lt; Line Line = "4" & gt; & Lt; Item id = "itembie 3" /> & Lt; / Line & gt; & Lt; Line Line = "5" & gt; & Lt; Item ID = "Item C1" /> & Lt; / Line & gt; & Lt; / Lines & gt; & Lt; / Order & gt;

So after sorting XML, 

   & Lt; / Line & gt; & Lt; Line Line = "5" & gt; & Lt; Item ID = "Item A4" /> & Lt; / Line & gt; & Lt; Line Line = "4" & gt; & Lt; Item ID = "ItemA7" /> & Lt; / Line & gt; & Lt; Line Line = "3" & gt; & Lt; Item id = "itembie 3" /> & Lt; / Line & gt; & Lt; Line Line = "2" & gt; & Lt; Item ID = "Item C1" /> & Lt; / Line & gt; & Lt; / Lines & gt; & Lt; / Order & gt;

I have written for this argument 

  Maps & lt; String, Element & gt; MapIDAndLine = New Hashmop & lt; String, Element & gt; (); Node list nlLine = doc.getElementsByTagName ("line"); (Element LLN = (element) elLine.item (cntLine); Element LITIM = ALLine.Get Child Element ("item") for (int cntLine = 0; cntLine & lt; nlLine.getLength (); cntLine ++); string sItemID = elItem.getAttribute ( "ID"); if (! Mapaidiandellaincontenski (the Itamaidi)) {mapIDAndLine.put (Saitiamaidi, Ellain);}} map & lt; string, string & gt; Trymark = new Trymark & ​​lt; String, String & gt; (Map ID Endline);

I get a map where all keys (Item ID ED) are sorted

Now I can iterate through the tree map and I can get this line and the doctor has removed the original lines.

Please tell me that I am doing something wrong here or there is a better way to do this.

Thanks in advance

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
