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>

输入文件名为空格左边的值内容为空格右边值
