读取文件格式为txt 文件类容为:

P0001-0001-0001	<TAXON_KEY ID="P0001-0001-0001"><Node num="1" id="0" parentnum="0"><num>1</num><text>茎、叶细胞薄壁；叶裂瓣横切面中央为1-2个大形细胞</text><taxon ID="P0001-0001-0001-0001"><zh>藻苔</zh><sci>T. lepidozioides</sci></taxon></Node><Node num="1" id="1" parentnum=""><num>1</num><text>茎、叶细胞壁明显加厚；叶裂瓣横切面中央有多数细胞</text><taxon ID="P0001-0001-0001-0002"><zh>角叶藻苔</zh><sci>T. ceratophylla</sci></taxon></Node></TAXON_KEY>
    P0001-0002-0001	<TAXON_KEY ID="P0001-0002-0001"><Node num="1" id="0" parentnum="0"><num>1</num><text>植物体粗短；叶扁椭圆形，长度短于宽度</text><taxon ID="P0001-0002-0001-0001"><zh>裸蒴苔</zh><sci>H. blumii</sci></taxon></Node><Node num="1" id="1" parentnum=""><num>1</num><text>植物体纤长；叶长椭圆形，长度长于宽度</text><taxon ID="P0001-0002-0001-0002"><zh>圆叶裸蒴苔</zh><sci>H. mnioides</sci></taxon></Node></TAXON_KEY> ....

输入文件名为空格左边的值 内容为空格右边值

public void test() {
    		try {
    			BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(new File("F:/desktop/aaa.txt")), "UTF-8"));

    				createFile("F:/desktop/txt/" + text[0] + ".txt");
    				writeFile("F:/desktop/txt/" + text[0] + ".txt", text[1]);
    			}
    		} catch (Exception e) {
    			System.err.println("read errors :" + e);
    		}

    			fw.write(Content);
    			fw.flush();
    			fw.close();
