是否和放大器;放大器;算一个或多个字符在XML文件？ [英] Does & count as one or multiple chars in an xml file?

问题描述

XML模式我正在与有特定的字符长度的字符串。所以，我可能有一个字符串，它是这样的：

The XML schema I'm working with has specific character lengths for strings. So I may have a string that's like:

吉姆＆放大器;玛丽

这是10个字符在C＃中，但是当它被写入到XML从而将其变为：

which is 10 chars in C# but when it is written to xml it becomes:

吉姆＆放大器;放大器;玛丽

如果XML模式表示，该字符串只可能是一个最大的10个字符。请问这个字符串传递？

If an XML schema said the string could only be a max of 10 chars. Would this string pass?

如果没有，我怎么可以测试在C＃中的字符串的长度，因为它会出现在XML？

If not, how can I test in C# for the string length as it would appear in XML?

感谢您的帮助。

推荐答案

我得出同样的结论马特（＆放大器;放大器; 是一个字符），但基于上的标准。该 XML标准指出的在的验证，属性值必须被归一化，其包括实体替换

I reach the same conclusion as Matt (& is a single character), but based on the standards. The XML standard states that before validation, attribute values must be normalized, which includes entity replacement.

另请参阅治疗实体部分，其中规定，他们将被包含无论是内容还是内部属性值的一部分。 包括有这个意思：它的置换文本被检索和处理，以取代基准本身，就好像它是引用已被识别的文档的位置的一部分。

Also see the Treatment of Entities section, which states that they would be "Included" whether they were part of content or inside attribute values. "Included" has this meaning: "its replacement text is retrieved and processed, in place of the reference itself, as though it were part of the document at the location the reference was recognized".
