There are more than enough splitting answers already, so here is another approach. If your input represents a tree structure, why not parse it to a tree? The following code was automatically translated from VB.NET, but it should work as far as I tested it. using System; using System.Collections.Generic; using...
Splitting at a specific point in PDFBox
One way to achieve the task, i.e. to split a page at a certain point (i.e. all content above a limit to be included and everything below to be excluded) would be to prepend a clip path. You can use this method: void clipPage(PDDocument document, PDPage page, BoundingBox clipBox) throws...

You are in the right path. You have to set the flag PREG_SPLIT_DELIM_CAPTURE in this way: $array = preg_split('/(<img .*>)/i', $string, -1, PREG_SPLIT_DELIM_CAPTURE); With multiple tag edited properly the regex: $string = 'Text <img src="hello.png" > hello <img src="bye.png" /> other text.'; $array = preg_split('/(<img[^>]+\>)/i', $string, -1, PREG_SPLIT_DELIM_CAPTURE); This will...

This may get a little 'ugly' but see if this works: =ArrayFormula(iferror(REGEXEXTRACT(" "&A1:A,"^"&REPT("\s+[^\s]+",COLUMN(OFFSET(A1,,,1,6))-1)&"\s+([^\s]+)"))) 6 in the offset denotes the (maximum) number of columns/groups that are outputted. as this is an arrayformula, no 'dragging down' is needed. ...
How to use Split() method in Android
java,android,string,list,split
I suggest you to use Pattern and Matcher classes. The below regex will capture the text present inside curly braces and then it would add them to the list variable. String myString = "A=myPage{a1,b1,c1};B=myPage{a2,b2,c2};C=myPage{a3,b3,c3};"; List<String> list = new ArrayList<String>(); Matcher m = Pattern.compile("\\{([^{}]*)\\}").matcher(myString); while(m.find()) { list.add(m.group(1)); } System.out.println(list); ...
prolog misunderstanding. Split list into two list with even and odd positions. where is my mistake?
The answer by CapelliC is perfect. Just to explain: When you have a Prolog clause like this: foo([H|T], [H|Z]) :- foo(T, Z). which you then call like this: ?- foo([a,b,c], L). from: foo([H| T ], [H|Z]) with H = a, T = [b,c], L = [a|Z] call: foo([a|[b,c]], [a|Z]) which...
hadoop large file does not split
performance,hadoop,split,mapreduce
dfs.block.size is not alone playing a role and it's recommended not to change because it applies globally to HDFS. Split size in mapreduce is calculated by this formula max(mapred.min.split.size, min(mapred.max.split.size, dfs.block.size)) So you can set these properties in driver class as conf.setLong("mapred.max.split.size", maxSplitSize); conf.setLong("mapred.min.split.size", minSplitSize); Or in Config file...
