java - Serialize a DOM document in UTF-8 -

-

i have been trying rid of com.sun.org.apache.xml.internal packages in code replacing them stable alternatives.

this 1 method i've replaced...

import com.sun.org.apache.xml.internal.serialize.lineseparator; import com.sun.org.apache.xml.internal.serialize.outputformat; import com.sun.org.apache.xml.internal.serialize.xmlserializer; ... ...      /**      * @param source      * @param target      * @throws ioexception      */     protected static void serialize( document source, writer target ) throws ioexception     {         outputformat outputformat = new outputformat( (document) source );         outputformat.setlineseparator( lineseparator.windows );         // format.setindenting(true);          outputformat.setlinewidth( 0 );         outputformat.setpreservespace( true );          xmlserializer serializer = new xmlserializer( target, outputformat );         serializer.asdomserializer();         serializer.serialize( source );     } // end serialize

this alternative found...

/**  * @param source  * @param target  * @throws ioexception  * @throws illegalaccessexception   * @throws instantiationexception   * @throws classnotfoundexception   * @throws classcastexception   */ protected static void serialize( document source, writer target ) throws exception {     domimplementationregistry registry = domimplementationregistry.newinstance();     domimplementationls impl = (domimplementationls) registry.getdomimplementation( "ls" );     lsserializer writer = impl.createlsserializer();     target.write( writer.writetostring(source) ); } // end serialize

however, showing difference in xml being produced.

it creates 

<?xml version="1.0" encoding="utf-16"?>

how can modified create utf-8 instead?

i think have use lsoutput:

lsoutput domoutput = impl.createlsoutput(); domoutput.setencoding(standardcharsets.utf_8.name()); domoutput.setcharacterstream(stringwriter);

see response here more details:

change com.sun.org.apache.xml.internal.serialize.xmlserializer & com.sun.org.apache.xml.internal.serialize.outputformat

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
