perl - Working with child nodes in subroutine (XML::LibXML) -

-

I parse some XML data in my small code, but since I need the same thing in 3 places , Then I would like to make a suboutine for every time but I need to pass the current node which I am working as an argument, beyond reaching the current node's hair nodes beyond its current skill.

Here is an example of my code: 

  foreach $ day ($ doc-> SearchNode ('/ my / current / path')) {@atts = $ Day-> GetAttributes (); Foreach $ at (@atts) {$ na = $ at- & gt; GetName (); $ Va = $ at- & gt; GetValue (); If ($ va eq "Today") {# ------ My double code starts here ----- foreach $ cheese ($ day- & gt; SearchNode ('child_nodes_im_looking_for')) {# - --- Do a lot of things} # ------ My double code ends -----} If ($ va eq "tomorrow") {#same repeat code} if ($ va eq "some_other_day" ) {# Once repeated code .... again) for the second day ... do not do anything

How do I pass my current node into subroutine so that I can directly Can your hair nodes enter the routine?

I believe that you have harden and Use warnings in effect? Even if you have, you should declare your variable as my as late at its first point of use as ideally as possible. .

I'm not clear what the problem really is, on its face, you have to give node $ day as a normal subtraction parameter.

This reconfiguration shows your code sample. If I have been misinterpreted to you then please say so. 

  For my $ day ($ doc- & searchnode ('/ my / present / path')) {my @atts = $ day-> GetAttributes (); For my $ et (@ts) {my $ na = $ att-> GetName; My $ va = $ et- & gt; GetValue; If ($ va eq 'today') {barrind ($ day); } If ($ va eq 'tomorrow') {barrind ($ day); } If ($ va eq 'some_other_day') {barrage ($ day); } # For the second day ... do not do anything}} sub-repeated {my ($ node) = @_; My $ cheese ($ node- & gt; search node ('child_nodes_im_looking_for')) {# ----- do a lot of things}}

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
