Question

我有以下代码从我的字符串中删除index.php出现次数：

final Pattern p = Pattern.compile("\\\"index\\.php\\?[^\"]*[;?]+id=([0-9]+)[^\"]*\\\"");
    String str = "1 serving Well-Seasoned Oven Roasted Pork Tenderloin<a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=794\"> (recipe)</a><br />1 serving Parsley Garlic Potatoes <a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=668\">(recipe)</a><br />\n</div>";

    Matcher m = p.matcher(str);
    while(m.find()) {
        try {
            String match = m.group();
            str = str.replaceAll(match, "abc.html");
            p.matcher(str);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    System.out.printf("final:" + str);

首先，我想获得“index.php？option = com_recipe＆amp; Itemid = 101”，然后获取商品ID值。

Answer 1

[所做的更改]如何关注：

    String str = "1 serving Well-Seasoned Oven Roasted Pork Tenderloin<a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=794\"> (recipe)</a><br />1 serving Parsley Garlic Potatoes <a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=668\">(recipe)</a><br />\n</div>";
    str = str.replaceAll("\\<a.*?\\</a>", "<a href=\\\\\"abc.html>(recipe)</a>");
    System.out.printf("final:" + str);

Answer 2

这应该替换所有出现的事件：

 str = str.replaceAll("index.php", "abc.html");

为什么在这里使用模式？

Answer 3

试试这个：

 String str = "1 serving Well-Seasoned Oven Roasted Pork Tenderloin<a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=794\"> (recipe)</a><br />1 serving Parsley Garlic Potatoes <a href=\"index.php?option=com_recipe&amp;Itemid=101&amp;r=668\">(recipe)</a><br />\n</div>";
 str = str.replaceAll("<a href=\"index.php.*?>", "<a href=\"abc.html\">");
 System.out.printf("final:" + str);

输出：

final:1 serving Well-Seasoned Oven Roasted Pork Tenderloin<a href="abc.html"> (recipe)</a><br />1 serving Parsley Garlic Potatoes <a href="abc.html">(recipe)</a><br />

Answer 4

我使用了jsoup库并修复了它，以下是我的代码：

Document doc = Jsoup.parse(data);
Elements elements = doc.select("a");
for(Element element: elements){
     String href = element.attr("href");
     data = data.replace(href, "abc.html");
}

从字符串中删除此特定字符串
