mysql - 如何使用 bash 文本处理命令将一个字符的单词元素转换为两个字符的单词元素？

Question

我在一个文件夹中有很多这样的脚本:

INSERT INTO fv_xml_binary_adim VALUES (1, '<FeatureVector><feature>project</feature><feature>w</feature><feature>focus</feature><feature>d</feature><feature>new</feature><feature>cut</feature><feature>tool</feature><feature>design</feature><feature>allow</feature><feature>increas</feature><feature>high</feature><feature>speed</feature><feature>machin</feature><feature>hsm</feature><feature>product</feature></FeatureVector>');

我想将单字符元素转换为双字符元素。我想将上面的命令转换成:

INSERT INTO fv_xml_binary_adim VALUES (1, '<FeatureVector><feature>project</feature><feature>w0</feature><feature>focus</feature><feature>d0</feature><feature>new</feature><feature>cut</feature><feature>tool</feature><feature>design</feature><feature>allow</feature><feature>increas</feature><feature>high</feature><feature>speed</feature><feature>machin</feature><feature>hsm</feature><feature>product</feature></FeatureVector>');
