c# - What is wrong with this file or code? -

-

what happening \ difference ? i'm trying return specific node xml file.

xml file:

  <?xml version="1.0" encoding="utf-8"?>     <jmf senderid="inkzone-controller" version="1.2">       <command id="cmd.00695" type="resource">         <resourcecmdparams resourcename="inkzoneprofile" jobid="k_41">           <inkzoneprofile id="r0013" class="parameter" locked="false" status="available" partidkeys="signaturename sheetname side separation" descriptivename="schieberwerte von di" zonewidth="32">             <inkzoneprofile signaturename="sig1">               <inkzoneprofile locked="false" sheetname="s1">                 <inkzoneprofile side="front" />               </inkzoneprofile>             </inkzoneprofile>           </inkzoneprofile>         </resourcecmdparams>       </command> <inkzoneprofile separation="cyan" zonesettingsx="0 0,005 " />     </jmf>

code:

           xmldocument xmldoc = new xmldocument();             xmldoc.load("c:\\test\\test.xml");             xmlnode root = xmldoc.documentelement;             var parent = root.selectsinglenode("/jmf/command/resourcecmdparams/inkzoneprofile/inkzoneprofile/inkzoneprofile/inkzoneprofile");              xmlelement izp = xmldoc.createelement("inkzoneprofile");             izp.setattribute("separation", x.colorname);             izp.setattribute("zonesettingsx", x.colorvalues);             xmldoc.documentelement.appendchild(izp);             xmldoc.save("c:\\test\\test.xml");

the var parent returns me null. i've debugged , , root , xmldoc have on inner text xml content. but, test made here(made user @har07 , on previous question: selectsinglenode returns null namespace managing worked without problems. https://dotnetfiddle.net/vj8h9s

what difference between 2 ? follow same code basically, 1 works , other doesn't.
when debugging i've found root.innerxml has contents loaded on (same xmldoc.innerxml ). innerxml doesn't implement method selectsinglenode. believe if save string i'll lose indentation , etc.

can tell me difference or wrong ? ! xml sample: https://drive.google.com/file/d/0bwu9_grfryrtufhmywk5blhhzwm/view?usp=sharing

setattribute don't auto escape string you. therefore make xml file invalid.

from msdn xmlelement.setattribute

any markup, such syntax recognized entity reference, treated literal text , needs escaped implementation when written out

find in code line contain setattribute , use securityelement.escape escape value.

for example: change these lines:

izp.setattribute("separation", x.colorname); izp.setattribute("zonesettingsx", x.colorvalues);

to:

using system.security;  izp.setattribute("separation", securityelement.escape(x.colorname)); izp.setattribute("zonesettingsx", securityelement.escape(x.colorvalues));

if attribute have name contains of <>"'& have escape value.

note:

you have delete current xmls create used old code, because invalid, when load cause exception.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...

filehandler - java open files not cleaned, even when the process is killed -

-
there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...
