xml - XPath to compare two distinct attributes of two elements -

-

मान लीजिए मुझे यह XML है: 

  & lt; x & gt; & Lt; e s = "1" t = "ए" / & gt; & Lt; e s = "2" t = "ए" / & gt; & Lt; e s = "1" t = "बी" / & gt; & Lt; / एक्स & gt;

क्या एक्सपैथ को लिखने के लिए कोई तरीका है, यह पता करने के लिए कि क्या "ई" नाम के दो अलग-अलग नोड हैं जो कि @ के समान मान हैं, लेकिन @t के विभिन्न मान पहला भाग आसान है: 

  // e [@s = // ई / @ s]

जैसा कि दूसरा भाग है: 

  // ई [@t! = // ई [@टी]]

लेकिन मुझे एक एक्सपेथ का निर्माण करने का कोई तरीका दिखाई नहीं देता जो दो अलग-अलग दो अलग तत्व "ई" के लिए विशेषताओं क्या xpath वाक्यविन्यास के भीतर कोई रास्ता है, या यह निराशाजनक है?

अनुरोधित नोड्स एक XPath 1.0 अभिव्यक्ति द्वारा चयनित किया जा सकता है।

अगर होस्टिंग भाषा XSLT 1.0 है, तो current () फ़ंक्शन का उपयोग करके एक अभिव्यक्ति का निर्माण किया जा सकता है, जो कि चयन करता है वांछित नोड्स।

निम्नलिखित XPath 2.0 अभिव्यक्ति का प्रयोग करें: 

  $ x में / * / ई [@s = (पूर्ववर्ती- Sibling :: ई | निम्नलिखित- sibling :: ई) / @ s], $ y में / * / ई [@s = $ x / @ s] वापसी $ x [नहीं (@t = $ y / @ टी]]

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

php - Login to icq account to receive messages from contact #12345678 -

-
What's the way php-script is running, which does the following: - Enter the icq-account - Received Existing contacts are all messages (if any) from # 12345678 and - write those messages in an array such as $ Messages = array (); Edit I like to answer: "Blaee" is a good, active community, it is often updated because ICQ changes its internal changes Let's see: The first result of that: This class can be used to communicate with other ICQ consumers. This can: Non-interception with an ICQ server Authenticate as a given user Get offline message Send and receive messages (...) I would say that code Looking for you.

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
