如何在XSL中从字符中去除重音符号？ [英] How do I strip accents from characters in XSL?

问题描述

我一直在寻找字符，但是找不到等效于 normalize-space的XSL函数。也就是说，我的内容带有重音UNICODE字符，这很好，但是从该内容中，我正在创建一个文件名，我不希望这些重音符号。

I keep looking, but can't find an XSL function that is the equivalent of "normalize-space", for characters. That is, my content has accented UNICODE characters, which is great, but from that content, I'm creating a filename, where I don't want those accents.

因此，是否存在我在忽略或无法正确搜索以轻松处理字符的内容？

So, is there something that I'm overlooking, or not googling properly, to easily process characters?

在XML数据中：

<filename>gri_gonéwiththèw00mitc</filename>

在XSLT样式表中：

<xsl:variable name="file">
    <xsl:value-of select="filename"/>
</xsl:variable>

<xsl:value-of select="$file"/>

结果为gri_gonéwiththèw00mitc

results in "gri_gonéwiththèw00mitc"

其中

<xsl:value-of select='replace( normalize-unicode( "$file", "NFKD" ), "[^\\p{ASCII}]", "" )'/>

没有任何结果。

我做什么我的目标是 gri_gonewiththew00mitc （不带重音符号）

What I'm aiming for is gri_gonewiththew00mitc (no accents)

我使用的语法错误吗？

推荐答案

在XSLT / XPath 1.0中，如果要将这些带重音符号的字符替换为无重音字符，可以使用 translate（） 函数。

In XSLT/XPath 1.0 if you want to replace those accented characters with the unaccented counterpart, you could use translate() function.

但是，假定您的重读UNICODE字符不是由unicode字符组成。如果是这种情况，则需要使用XPath 2.0 normalize-unicode（）函数。

But, that assumes your "accented UNICODE characters" aren't composed unicode characters. If that were the case, you would need to use XPath 2.0 normalize-unicode() function.

然后，如果真正的目标是拥有有效的URI，则应使用 en-for-uri（）

And, if the real goal is to have a valid URI, you should use encode-for-uri()

更新：示例

translate('gri_gonéwiththèw00mitc','áàâäéèêëíìîïóòôöúùûü','aaaaeeeeiiiioooouuuu')

结果： gri_gonewiththew00mitc

encode-for-uri('gri_gonéwiththèw00mitc')

结果： gri_gon％C3％A9withth％C3％A8w00mitc

正确的表达式由@biziclop提供建议：

Correct expression provide suggest by @biziclop:

replace(normalize-unicode('gri_gonéwiththèw00mitc','NFKD'),'\P{ASCII}','')

结果： gri_gonewiththew00mitc

注意：我在XPath 2.0中，正确的字符类取反是大写的 \P 。

Note: In XPath 2.0, the correct character class negation is with a capital \P.
