jQuery包含精确搜索 [英] JQuery contains exact search

问题描述

我正在使用JQuery解析一些xml并遇到以下行的问题:

I'm using JQuery to parse some xml and having trouble with the line below:

$(xml).find("ACT:contains(" + selectedAct + ")>SCENE").each(function()

例如，如果选定的行为是"ACT I"，那么上面的行不仅会找到"ACT I"，还会找到"ACT II"，"ACT IV"，依此类推，即返回所有行为包含变量selectedAct.

For example, if the selected act is 'ACT I', then the above line finds not only 'ACT I', but also 'ACT II', 'ACT IV', and so on, i.e. it is returning all acts that contain the variable selectedAct.

我们非常感谢您的帮助.我已经看到了将过滤器"与匿名函数结合使用的示例，但是我不知道如何根据上面的代码来构造它.

Any help is much appreciated. I've seen examples where 'filter' is used with an anonymous function, but I don't know how to structure it in relation to my code above.

有什么想法吗?

非常感谢

XML示例:

<ACT><TITLE>ACT I</TITLE>

<SCENE><TITLE>SCENE I.  Alexandria. A room in CLEOPATRA's palace.</TITLE>
<STAGEDIR>Enter DEMETRIUS and PHILO</STAGEDIR>

<SPEECH>
<SPEAKER>PHILO</SPEAKER>
<LINE>Nay, but this dotage of our general's</LINE>

<!ELEMENT LINE     (#PCDATA | STAGEDIR)*>
<!ELEMENT STAGEDIR (#PCDATA)>
<!ELEMENT SUBTITLE (#PCDATA)>
<!ELEMENT SUBHEAD  (#PCDATA)>

推荐答案

尝试一下:

$(xml).find("ACT > TITLE").filter(function() {
    return this.firstChild.nodeValue === selectedAct;
}).siblings('SCENE').each(function() {...
