如何使用 MACROMAN 编码解析 xml

Question

我试图解析给定的pom内容，但出错了：xml：打开字符集“MACROMAN”：不支持的字符集：“MACROMAN”。我试图通过设置解码器来禁用严格编码。严格 = 假，但这也不起作用。

这是Go Playground链接，我正在解析这个特定的pom。任何帮助/参考将不胜感激。

<?xml version="1.0" encoding="MACROMAN"?>

以下是 Go 中编码的已知别名：macintoshvar nameMap = map[string]htmlEncoding{&nbsp; &nbsp; // ...&nbsp; &nbsp; "csmacintosh":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;macintosh,&nbsp; &nbsp; "mac":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;macintosh,&nbsp; &nbsp; "macintosh":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;macintosh,&nbsp; &nbsp; "x-mac-roman":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;macintosh,&nbsp; &nbsp; // ...}由于 不在该列表中，因此您可以使用函数字段通过设置macromanCharsetReader&nbsp; &nbsp; decoder.CharsetReader = charsetReader在哪里：charsetReaderfunc charsetReader(charset string, input io.Reader) (io.Reader, error) {&nbsp; &nbsp; if isCharsetMacintosh(charset) {&nbsp; &nbsp; &nbsp; &nbsp; return transform.NewReader(input, charmap.Macintosh.NewDecoder()), nil&nbsp; &nbsp; }&nbsp; &nbsp; return input, nil}var macNames = []string{&nbsp; &nbsp; "macroman",&nbsp; &nbsp; "csmacintosh",&nbsp; &nbsp; "mac",&nbsp; &nbsp; "macintosh",&nbsp; &nbsp; "x-mac-roman",}func isCharsetMacintosh(charset string) bool {&nbsp; &nbsp; charset = strings.ToLower(charset)&nbsp; &nbsp; for _, n := range macNames {&nbsp; &nbsp; &nbsp; &nbsp; if charset == strings.ToLower(n) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return true&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; return false}如果您需要更多信息，这里的答案可能会有所帮助：在Go中取消ISO-8859-1 XML输入。查看函数的源代码并遵循函数调用也很有帮助。charset.NewReaderLabel
