how to check if xml file has more than one child values using php -

-

मेरे पास XML फ़ाइल है $ file.xml जिसमें निम्न शामिल हैं 

  & lt;? Xml संस्करण = "1.0"? & Gt; & LT; नाम & gt; & lt; नाम & gt; name1 & lt; / नाम & gt; & lt; नाम & gt; NAME2 & lt; / नाम & gt; & lt; नाम & gt; NAME3 & lt; / नाम & gt; & lt; / नाम & gt;

मुझे यह जांचने के लिए एक तरीका है कि अगर & lt; नाम & gt; एक से अधिक बच्चे है, & lt; name & gt; नाम 1 & lt; / name & gt; whick से अधिक है इसका मतलब है कि यदि & lt; name & gt; name2 & lt; / name & gt; या फ़ंक्शन कॉल करने के लिए मौजूद है।

मैंने निम्नलिखित की कोशिश की है 

  $ file = "file.xml"; $ Result = file_get_contents ($ file);

file_get_contents ने मुझे पहले से ही मान दिया है Name1 name2 और name3

लेकिन यदि (@count (फ़ाइल ($ परिणाम)) 1) { कुछ भी नहीं

पहले से धन्यवाद

जी हाँ, यह संभव है, आप इस मामले के साथ संयोजन के रूप में xpath का उपयोग कर सकते हैं: 

  $ file = "file.xml"; $ Xml = simplexml_load_file ($ फ़ाइल); $ नाम = $ xml- & gt; xpath ('/ नाम / नाम'); अगर (गणना ($ नाम) & gt; 1) {// एक फ़ंक्शन एको प्रदर्शन 'प्रदर्शन!'; }

या DOMDocument के साथ विकल्प xpath के साथ भी: 

  $ dom = new DOMDocument (); $ Dom- & gt; लोड ($ फ़ाइल); $ Count = $ xpath- & gt; मूल्यांकन करें ('गणना (/ नाम / नाम)'); यदि ($ count & gt; 1) {गूंज 'प्रदर्शन!'; }

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
