Jsoup getElementsByAttributeValueMatching(Jsoup getElementsByAttributeValueMatching)

 [JSoup讨论页面建议我在这里问我的问题。] 
 
 所以，我不是正则表达式专家，但我想知道我从jsoup getElementsByAttributeValueMatching（）方法得到的结果。 
 
 如果我有一个html页面，其中包含（以及其他）以下链接： 
 
<a href="/tweb/tiles/twr/EIDS_AT_20130108T134335/01/">Parent Directory</a>
<a href="1357681618315/">1357681618315/</a>
<a href="1357681649996/">1357681649996/</a>
 
 我查询： 
 
Elements dirs = baseDir.getElementsByAttributeValueMatching("href", Pattern.compile("[0-9]+/"));
 
 希望只获得只有数字的2个链接（以及最后的斜杠）。 
 
 但是，我得到了所有3个链接。 
 
 我编写了一个快速测试程序，用3 href字符串检查java的Pattern Matcher对该正则表达式的响应，并且它只返回两个只有我期望的数字： 
 
String a = "/tweb/tiles/twr/EIDS_AT_20130108T134335/01/";
String b = "1357681618315/";
String c = "1357681649996/";

Pattern p = Pattern.compile("[0-9]+/");

System.out.println("a:"+ p.matcher(a).matches());
System.out.println("b:"+ p.matcher(b).matches());
System.out.println("c:"+ p.matcher(c).matches());
 
 返回：a：false b：true c：true 
 
 所以，我的问题是，我错过了什么？ 
 
 谢谢，Linus 

[the JSoup discussion page suggested I ask my question here.]
 
So, I am no regex expert, but I'm wondering about the results I get from the jsoup getElementsByAttributeValueMatching() method.
 
If I have an html page that has (among others) the following links:
 
<a href="/tweb/tiles/twr/EIDS_AT_20130108T134335/01/">Parent Directory</a>
<a href="1357681618315/">1357681618315/</a>
<a href="1357681649996/">1357681649996/</a>
 
And I query with:
 
Elements dirs = baseDir.getElementsByAttributeValueMatching("href", Pattern.compile("[0-9]+/"));
 
hoping to get just the 2 links that have only numbers (and a slash at the end.)
 
However, I get all 3 links back.
 
I wrote a quick test program to check java's Pattern Matcher response to that regex with the 3 href strings, and it returns only the two with only numbers as I would expect:
 
String a = "/tweb/tiles/twr/EIDS_AT_20130108T134335/01/";
String b = "1357681618315/";
String c = "1357681649996/";

Pattern p = Pattern.compile("[0-9]+/");

System.out.println("a:"+ p.matcher(a).matches());
System.out.println("b:"+ p.matcher(b).matches());
System.out.println("c:"+ p.matcher(c).matches());
 
returns: a:false b:true c:true
 
So, my question is, what am I missing?
 
thanks, Linus
