php - XML replace content to other -

-

मुझे यह स्क्रिप्ट है: 

  $ dom = new DOMDocument (); $ एक्सएमएल = '.. / आस्तियों / local.xml'; $ Dom- & gt; लोड ($ एक्सएमएल); $ Cdata = $ Dom- & gt; createCDATASection ('95 .55.4.2 '); विदेशी मुद्रा ($ dom- & gt; getElementsByTagName ('कनेक्शन') $ आइटम के रूप में) {$ item- & gt; getElementsByTagName ('होस्ट') - & gt; आइटम (0) - & gt; एपेंडबल्ड ($ cdata); } $ Dom- & gt; सहेजें ($ xml);

और मेरा XML है: 

  & lt; कनेक्शन & gt; & LT; मेजबान & gt; स्थानीय होस्ट & lt; / मेजबान & gt; & Lt; / कनेक्शन & gt;

और मुझे सीडीटाए से "लोकलहोस्ट" को "95.55.4.2" में बदलना होगा। मैं इस शेयर की कोशिश करता हूं लेकिन वह गलत है ... इसका नतीजा है: 

  & lt; कनेक्शन & gt; & LT; मेजबान & gt; 95.55.4.2localhost & lt; / मेजबान & gt; & Lt; / कनेक्शन & gt;   
 
 "> 
 आप नोड मान को सीधे सेट करने के लिए  nodeValue  का उपयोग कर सकते हैं: 
 
  $ dom = new DOMDocument (); $ एक्सएमएल = '.. / आस्तियों / local.xml'; $ Dom- & gt; लोड ($ एक्सएमएल); # तत्व का सीधे उपयोग करें: यह डॉक्टर में पहला "होस्ट" नोड है: $ dom- & gt; getElementsByTagName ('होस्ट') - & gt; आइटम (0) - & gt; नोड वेले = '95 .55.4.2 '; $ Dom- & gt; बचाने ($ एक्सएमएल);   
  appendChild  का उपयोग कर अपने सीडीएटीए नोड को मौजूदा बाल नोड्स में जोड़ देगा, यही वजह है कि आपको पुरानी और नई स्ट्रिंग्स का संयोजन मिल रहा है।

I need to convert a QByteArray into a structure.

I was already using the union but I think it can not be used for QByteArray, i...

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
