编码以数字开头的 XML 元素名称? [英] Encoding XML element name beginning with a number?

问题描述

我正在查看工具的输出，将数据库表转储到 XML.其中一列名为 64kbit ，该工具对其进行编码，我需要复制它:

I'm looking at the output of a tool, dumping a database table to XML. One of the columns is named 64kbit , the tool encodes that as such, and I need to replicate that:

 <_x0036_4kbit>0</_x0036_4kbit>

这是某种标准编码吗?我在哪里可以了解更多信息?

Is this some sort of standard encoding ? Where can I learn more about it ?

推荐答案

好吧，这似乎不太标准，但 XML 明确不允许将数字(和其他一些东西)作为元素名称的第一个字符:

Well, it doesn't seem to be too standard, but XML explicitly disallows numbers (and some other things) as the first character of an element name:

NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] |
                  [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] |
                  [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] |
                  [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] |
                  [#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

如果不符合要求，这里的编码只是对第一个字符进行转义.它使用该字符的十六进制值._x0036_显然对应的是十六进制的0x36，也就是十进制的54，代表数字6.

This encoding here just kinda escapes the first character if it doesn't fit that requirements. It uses the hexadecimal value of that character. _x0036_ obviously corresponds to hexadeximal 0x36 which is 54 in decimal and represents the digit 6.
