如何用perl将普通文本转换成数据库可以读取的文本？如下面例子

在一个txt文件中有如下数据
# This file contains data on the following fields from the Unihan database:
# kCompatibilityVariant
# kSemanticVariant
# kSimplifiedVariant
# kSpecializedSemanticVariant
# kTraditionalVariant
# kZVariant
#
# For details on the file format, see http://www.unicode.org/reports/tr38/
#
U+3400 kSemanticVariant U+4E18
U+3405 kSemanticVariant U+4E94<kMatthews
U+342B kSemanticVariant U+51F6
U+342E kSemanticVariant U+8944
U+342F kSemanticVariant U+5EB8
U+3431 kSemanticVariant U+9B12<kMatthews
U+3434 kSemanticVariant U+6500
U+3441 kSemanticVariant U+20B74
U+3444 kSemanticVariant U+4FAE<kMatthews
U+344C kSemanticVariant U+5C29<kMatthews
U+345D kSemanticVariant U+22671<kMeyerWempe
U+3469 kTraditionalVariant U+5138
U+346E kSimplifiedVariant U+2B748
U+346F kSimplifiedVariant U+3454
U+346F kTraditionalVariant U+3454
U+3473 kSimplifiedVariant U+3447
U+3473 kTraditionalVariant U+3447
U+3487 kSemanticVariant U+511B<kMatthews
U+348B kSemanticVariant U+5EDD<kMatthews U+53AE<kMatthews
U+3493 kSimplifiedVariant U+20242
U+3493 kTraditionalVariant U+20242
U+349A kSemanticVariant U+7A69<kFenn,kMatthews
U+349A kSpecializedSemanticVariant U+6587<kFenn
U+349E kSemanticVariant U+5136<kMatthews
U+34B0 kSemanticVariant U+5168<kMatthews
U+34B2 kSemanticVariant U+8CA1<kMatthews
U+34B7 kSemanticVariant U+8208<kLau,kMatthews
U+34B7 kSpecializedSemanticVariant U+8208<kFenn
U+34C1 kSemanticVariant U+7F51<kMatthews
U+34DF kSpecializedSemanticVariant U+62AB<kMeyerWempe
U+34E5 kTraditionalVariant U+528F
U+34E8 kSimplifiedVariant U+523E
U+34E8 kTraditionalVariant U+523E
变成形如下面这样的：
kUnihan kCompatibilityVariant kSemanticVariant kSimplifiedVariant kSpecializedSemanticVariant kTraditionalVariant kZVariant

U+34DF U+62AB<kMeyerWempe
U+34E5 U+528F
U+34E8 U+523E U+523E
存到另一个文本文件中，没有的值的就用空格。求高手指点
