xml - Python ElementTree child node from one tree to another -


i have multiple xml files similar layout.

in following example i've done changes xml tree 1, object 1 , copy changes xml tree 2 , 3:

example xmls:

<example_data>   <object class="example" id="xml_tree_1">     <object class="multi_object" id="object_1">       <style many_attributes="stuff_and_changes"/>       <object class="object_1" id="random_12">         <style many_attributes="things"/>       </object>       <object class="object_2" id="random_21">         <style many_attributes="things"/>       </object>     </object>     <object class="object_1" id="object_2">       <style many_attributes="stuff"/>     </object>   </object> </example_data>  <example_data>   <object class="example" id="xml_tree_2">     <object class="multi_object" id="object_1">       <style many_attributes="stuff"/>       <object class="object_1" id="random_23">         <style many_attributes="stuff"/>       </object>       <object class="object_2" id="random_32">         <style many_attributes="stuff"/>       </object>     </object>     <object class="object_1" id="object_2">       <style many_attributes="stuff"/>     </object>   </object> </example_data>  <example_data>   <object class="example" id="xml_tree_3">     <object class="multi_object" id="object_1">       <style many_attributes="stuff"/>       <object class="object_1" id="random_45">         <style many_attributes="stuff"/>       </object>       <object class="object_2" id="random_54">         <style many_attributes="stuff"/>       </object>     </object>     <object class="object_1" id="object_2">       <style many_attributes="stuff"/>     </object>   </object> </example_data>

after have done changes 1 tree, how can copy changes other trees also?

i don't know how started.

example python:

import os import xml.etree.elementtree et   all_trees = {}   def main():    generate_trees("path_to_xmls")    copy_style_attributes_to_all_trees("object_1", "xml_tree_1")    write_trees()   def copy_style_attributes_to_all_trees(object_id, source):    key in all_trees:     tree = all_trees[key]      dest in tree.iter("object"):       if (dest.get("id") == object_id):         # copy object 1 (and inner objects) style source dest object         # have no idea how   def generate_trees(directory):    root, dirs, files in os.walk(directory):     f in files:       if f.endswith(".xml"):         fpath = os.path.join(root, f)         tree = et.parse(fpath)         all_trees[fpath] = tree   def get_tree(filename):   key in all_trees:     if (key.find(filename) != -1):       return all_trees[key]   return none   def write_trees():    fpath in all_trees:     all_trees[fpath].write(fpath)   if __name__ == '__main__':   main()

how should done?

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
