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।

Active Directory Authenticated Proxy Server with Squid or CNTLM -

I need to configure a proxy server for a local network that authenticates with Active Directory and gives me access The control list enables you to configure the domain groups within AD.

python - Calculate STD manually using Groupby Pandas DataFrame -

Image
I was trying to write a solution, which is a different and a manual for calculating a mean and STD The way. I have created a = ["Apple", "Banana", "Cherry", "Apple"] B = [3,4,7,3] C = [5,4,1,4] D = [7,8,3,7] Pd DF = PD to import pandals DataFrame (index = class (4), column = list ("ABCD")) DF ["A"] = A DF ["B"] = BDF ["C"] = C DF ["D"] = D Again, I made a list of A duplication. Then I went through the group all the time of the objects and calculated the solution. import as np l = list (set (df.A)) df.groupby ('A', As_index = False) listMean = [0] * len (df.C) ListSTD = [0] * L in the LAN (df.C) X: s = np.mean (df [df ['A'] == x] for C =.) = Z = [index for index, enumerate In the object (df ['a']. Value] x == item i for z: listMean [i] = s in: s = np.std (df [df ['a'] == X] .cvalues) z = index for index, enumerate item (df ['a']. Value) if x ==...
