java - XmlPullParserException during parsing XML with XMLPullParser -

-

need resolve : trying parse xml -

<lungprotocol><configuration name="flus sitting">        <segment order="1" name="left upper anterior">     <segment order="2" name="left lower anterior">   </configuration> <configuration name="flus supine">       <segment order="1" name="left upper anterior">     <segment order="2" name="left lower anterior"> </configuration></lungprotocol>

with following function - 

public list<lungsegment> parse(inputstream is, string configuration) {          try {           xmlpullparserfactory factory = xmlpullparserfactory.newinstance();           factory.setnamespaceaware(true);           xmlpullparser  parser = factory.newpullparser();           segment = new lungsegment();         parser.setinput(is, null);           parser.require(xmlpullparser.start_tag, null, "configuration");         int eventtype = parser.geteventtype();         while (eventtype != xmlpullparser.end_document) {               string tagname = parser.getname();               switch (eventtype) {               case xmlpullparser.start_tag:                   if(("configuration").equalsignorecase(tagname) && parser.getattributevalue(null, "name").equalsignorecase(configuration)){                     eventtype = parser.next();                     //eventtype = parser.next();                     tagname = parser.getname();                     log.v("xmltag", "configuration = "+configuration);                 if (("segment").equalsignorecase(tagname)) {                       // create new instance of segment                         segment = new lungsegment();                       segment.setsegmentname(parser.getattributevalue(null, "name"));                       segment.setsegmentorder(integer.parseint(parser.getattributevalue(null, "order")));                 }                  }                 break;                case xmlpullparser.end_tag:                   if (tagname.equalsignorecase("segment")) {                       // add segment object list                       segments.add(segment);                   } else if (("configuration").equalsignorecase(tagname) && parser.getattributevalue(null, "name").equalsignorecase(configuration)) {                         return segments;                 }                   break;                }               eventtype = parser.next();           }        } catch (xmlpullparserexception e) {e.printstacktrace();}        catch (ioexception e) {e.printstacktrace();}        return segments;   }

where configuration name attribute of configuration tag. getting exception -

org.xmlpull.v1.xmlpullparserexception: expected: start_tag {null}configuration (position:start_document null@1:1 in java.io.inputstreamreader@42323800)

please me going wrong.

make these 2 changes in code:

  1. make xml valid. segment tags not ended. should be:<segment order="1" name="left upper anterior"/>

  2. remove line parser.require(xmlpullparser.start_tag, null, "configuration");

everything else looks fine. able run code well.

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

here's current code creating index jsonb. index("mytable_data_idx_id_key", mytable.data['id'].astext, postgresql_using='gin') but got error. sqlalchemy.exc.programmingerror: (psycopg2.programmingerror) data type text has no default operator class access method "gin" hint: must specify operator class index or define default operator class data type.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
