xml - PHP SimpleXML: insert node at certain position -

-

का कहना है कि मेरे पास एक्सएमएल है: 

  & lt; root & gt; & Lt; नोडए / & gt; & Lt; नोडए / & gt; & Lt; नोडए / & gt; & Lt; nodeC / & gt; & Lt; nodeC / & gt; & Lt; nodeC / & gt; & Lt; / जड़ & gt;

मैं as और Cs के बीच "nodeB" कैसे सम्मिलित कर सकता हूं? PHP में, अधिमानतः SimpleXML के माध्यम से? जैसे: 

  & lt; रूट & gt; & Lt; नोडए / & gt; & Lt; नोडए / & gt; & Lt; नोडए / & gt; & Lt; nodeB / & gt; & Lt; nodeC / & gt; & Lt; nodeC / & gt; & Lt; nodeC / & gt; & Lt; / जड़ & gt;

निम्नलिखित कुछ अन्य SimpleXMLElement के बाद एक नया SimpleXMLElement सम्मिलित करने के लिए एक फ़ंक्शन है। चूंकि यह सिंपलएक्सएमएल के साथ सीधा संभव नहीं है, इसलिए यह काम पाने के लिए कुछ वर्गों / तरीकों का इस्तेमाल करता है। 

  फ़ंक्शन सिम्प्लेक्सएमएलएनिर्ट_after (सरल एक्सएमएलमेंट $ डालें, सरल एक्सएमएलमेंट $ लक्ष्य) {$ Target_dom = dom_import_simplexml ($ लक्ष्य); $ Insert_dom = $ target_dom- & gt; स्वामी दस्तावेज़- & gt; आयातनोड (dom_import_simplexml ($ सम्मिलित करें), सच है); यदि ($ target_dom- & gt; अगला सिबलिंग) {return $ target_dom- & gt; parentNode- & gt; सम्मिलित करें ($ insert_dom, $ target_dom- & gt; अगले सिबलिंग); } और {वापसी $ target_dom- & gt; parentNode- & gt; एपेंड चाइल्ड ($ insert_dom); }}

और इसका इस्तेमाल कैसे किया जा सकता है (आपके प्रश्न के लिए विशिष्ट): 

  $ sxe = new SimpleXMLElement ('& lt; root & gt; & LT; nodeA / & gt; & lt; nodeA / & gt; & lt; nodeA / & gt; & lt; nodeC / & gt; & lt; nodeC / & gt; & lt; nodeC / & gt; & lt; / जड़ & gt; '); // नया तत्व डालने के लिए $ insert = नया SimpleXMlelement ("& lt; nodeB / & gt;"); // अंतिम नोड ए तत्व प्राप्त करें $ target = current ($ sxe-> xpath ('// nodeA [last ()]')); // अंतिम नोड के बाद नया तत्व सम्मिलित करें simplexml_insert_after ($ डालें, $ लक्ष्य); // नए एक्सएमएल पर क्लिक करें प्रतिध्वनि $ sxe- & gt; asXML ();

यदि आप कैसे यह काम करता है (कोड काफी सरल है लेकिन विदेशी अवधारणाओं में शामिल हो सकते हैं) की व्याख्या की आवश्यकता है, तो बस पूछें।

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
