Parsing XML in Python -


i have large xml file , need format needed data particular elements in , print out data needed file. in xml file have number of text tags belonging different conversations id's , authors have id's after author tag. not need texts authors specific ones whom have id's. how write function specifies select , write out conversations author = id1 or id2 or id3.......etc? document looks like...

 <conversations>   <conversation id="e621da5de598c9321a1d505ea95e6a2d">     <message line="1">       <author>97964e7a9e8eb9cf78f2e4d7b2ff34c7</author>       <time>03:20</time>       <text>hola.</text>     </message>     <message line="2">       <author>0158d0d6781fc4d493f243d4caa49747</author>       <time>03:20</time>       <text>hi.</text>     </message>   </conversation>   <conversation id="3c517e43554b6431f932acc138eed57e">     <message line="1">       <author>505166bca797ceaa203e245667d56b34</author>       <time>18:11</time>       <text>hi</text>     </message>     <message line="2">   </conversation>   <conversation id="3c517e43554b6431f932acc138eed57e">      <author>505166bca797ceaa203e245667d56b34</author>       <time>18:11</time>       <text>aujourd.</text>     </message>     <message line="3">       <author>4b66cb4831680c47cc6b66060baff894</author>       <time>18:11</time>       <text>hey</text>     </message>   </conversation>     </conversations>  

import xml.etree.elementtree et tree = et.parse('conversations.xml') node in tree.iter():     if node.tag == "conversations":         continue     if node.tag == "conversation":         print("\n")  # visual break, new conversation         print("{} {}".format(node.tag, node.attrib))         continue     if node.tag == "message":         print("{} {}".format(node.tag, node.attrib))         continue     print("{} {}".format(node.tag, node.text))

so using above should able check id, using similar logic if searching 97964e7a9e8eb9cf78f2e4d7b2ff34c7, etc, make list or dict.

authors = ['97964e7a9e8eb9cf78f2e4d7b2ff34c7'] node in tree.iter():     if node.tag == "author" , node.text in authors:         print('found')

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
