jquery中不支持的xpath函数 [英] xpath functions not supported in jquery

问题描述

我有以下需要运行的xpath，但是Jquery不支持这些功能....那么我如何才能在jquery中真正实现此功能?

I have the following xpath that I need to run, but Jquery doesn't support the functions....so how can i actually make this work in jquery ?

$("//*[br]/text()[string-length(normalize-space()) != 0]").each( ....

推荐答案

嗯-现代jQuery不支持XPath. jQuery不是Xpath解析工具.

Um - modern jQuery doesn't support XPath. jQuery isn't an Xpath parsing utility.

但是，我建议您实际上将其翻译成jQuery ...也许类似

However, I would recommend you actually translate that into jQuery... perhaps something like

$('*[br]').filter(function() {
    var text = $(this).text(), normalized = $.trim( text );
    return normalized.length>0
});

尽管您可能需要对多个空格进行额外的正则表达式替换，但我不确定xsl/xpath函数的工作方式.

Though you may need an additional regex replacement of multiple whitespace, I'm not quite sure how that xsl/xpath function works.
