php - Access instance variables with special characters -

-

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 4 जवाब

    का प्रयोग कर SimpleXML < / Code> PHP में, मैं केवल & lt; lj: उत्तर-गणना & gt; नोड मान को पकड़ना चाहता हूं।

    XML: 

      & LT; LJ: सुरक्षा & gt; सार्वजनिक & lt; / LJ: सुरक्षा & gt; & LT; LJ: posterid & gt; 631,636 & lt; / LJ: posterid & gt; & LT; LJ: जबाब गिनती & gt; 42 & lt; / LJ: जबाब गिनती & gt;   
     इस तरह से सॉर्ट करें, लेकिन स्पष्ट रूप से बिल्कुल नहीं, क्योंकि यह PHP पार्स त्रुटियों को फेंक देगा  
      if ($ item- & gt; lj: reply-count ) $ उत्तरकाउंट = $ item- & gt; lj: उत्तर-गिनती   
     मैंने कुछ अन्य बदलावों की कोशिश की और Google ने चारों ओर घूम लिया, लेकिन मुझे लगता है कि मैं क्या ढूंढ रहा हूं । धन्यवाद।   
     
     
     चूंकि आपके एक्सएमएल के नाम स्थान हैं, इसलिए आपको उसके लिए विधि का उपयोग करना होगा। उदाहरण:  
      $ xml_string = & lt; & lt; & lt; XML & lt;? Xml संस्करण = "1.0" एन्कोडिंग = "UTF-8"? & Gt; & Lt; रूट xmlns: lj = "http://www.example.com/" & gt; & LT; LJ: सुरक्षा & gt; सार्वजनिक & lt; / LJ: सुरक्षा & gt; & LT; LJ: posterid & gt; 631,636 & lt; / LJ: posterid & gt; & LT; LJ: जबाब गिनती & gt; 42 & lt; / LJ: जबाब गिनती & gt; & Lt; / जड़ & gt; एक्सएमएल; $ Xml = सरल एक्सएमएललोड_स्ट्रिंग ($ xml_स्ट्रिंग); $ Lj = $ xml- & gt; बच्चों ('एलजे', 'http://www.example.com/'); $ Answer_count = (स्ट्रिंग) $ lj- & gt; {'उत्तर-गिनती'}; गूंज $ answer_count; // 42

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
