beautifulsoup - How to retain " and ' while parsing xml using bs4 python -

-

i using bs4 parse xml file , again write new xml file.

input file: 

<tag1>   <tag2 attr1="a1">&quot; example text &quot;</tag2>   <tag3>     <tag4 attr2="a2">&quot; example text &quot;</tag4>     <tag5>       <tag6 attr3="a3">&apos; example text &apos;</tag6>     </tag5>   </tag3> </tag1>

script:

soup = beautifulsoup(open("input.xml"), "xml") f = open("output.xml", "w")  f.write(soup.encode(formatter='minimal')) f.close()

output:

<tag1>   <tag2 attr1="a1"> " example text "  </tag2>   <tag3>     <tag4 attr2="a2"> " example text " </tag4>     <tag5>       <tag6 attr3="a3"> ' example text ' </tag6>     </tag5>   </tag3> </tag1>

i want retain &quot; , &apos; . tried using options of encode formatter - minimal, xml, html, none. none of them solved problem.

then tried replacing " &quot; manually.

for tag in soup.find_all(text=re.compile("\"")):     res = tag.string     res1 = res.replace("\"","&quot;")     tag.string.replacewith(res1)

but gave below output 

<tag1>   <tag2 attr1="a1"> &amp;quot; example text &amp;quot;  </tag2>   <tag3>     <tag4 attr2="a2"> &amp;quot; example text &amp;quot; </tag4>     <tag5>       <tag6 attr3="a3"> &apos; example text &apos; </tag6>     </tag5>   </tag3> </tag1>

it replaces & &amp; . confused here. please me in solving this.

custom encode & output formatting

you can use custom formatter function add these specific entities entity substitution.

from bs4 import beautifulsoup bs4.dammit import entitysubstitution  def custom_formatter(string):     """add &quot; , &apos; entity substitution"""     return entitysubstitution.substitute_html(string).replace('"','&quot;').replace("'",'&apos;')  input_file = '''<tag1>   <tag2 attr1="a1">&quot; example text &quot;</tag2>   <tag3>     <tag4 attr2="a2">&quot; example text &quot;</tag4>     <tag5>       <tag6 attr3="a3">&apos; example text &apos;</tag6>     </tag5>   </tag3> </tag1> '''  soup = beautifulsoup(input_file, "xml")  print soup.encode(formatter=custom_formatter) 
<?xml version="1.0" encoding="utf-8"?> <tag1> <tag2 attr1="a1">&quot; example text &quot;</tag2> <tag3> <tag4 attr2="a2">&quot; example text &quot;</tag4> <tag5> <tag6 attr3="a3">&apos; example text &apos;</tag6> </tag5> </tag3> </tag1>

the trick after entitysubstitution.substitute_html() &s don't substituted &amp;s.

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
