我正在使用JQuery来解析一些xml并且遇到以下问题:
$(xml).find("ACT:contains(" + selectedAct + ")>SCENE").each(function()
例如,如果所选行为是'ACT I',那么上述行不仅会找到'ACT I',还会找到'ACT II','ACT IV'等等,即它返回所有行为包含变量selectedAct。
非常感谢任何帮助。我已经看过'过滤器'与匿名函数一起使用的例子,但我不知道如何根据我上面的代码构造它。
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>

答案 0 :(得分:2)
试试这个:
$(xml).find("ACT > TITLE").filter(function() {
return this.firstChild.nodeValue === selectedAct;
}).siblings('SCENE').each(function() {...

您可以尝试扩展选择器...我在我的博客中暂时制作了demo。
$.extend($.expr[':'],{
containsExact: function(a,i,m){
return $.trim(a.innerHTML.toLowerCase()) === m[3].toLowerCase();
},
containsExactCase: function(a,i,m){
return $.trim(a.innerHTML) === m[3];
},
containsRegex: function(a,i,m){
var regreg = /^\/((?:\\\/|[^\/])+)\/([mig]{0,3})$/,
reg = regreg.exec(m[3]);
return RegExp(reg[1], reg[2]).test($.trim(a.innerHTML));
}
});
