问题 I have the following text Ad:<font class=value>1234 Blues </font> Regex expression value>([^<]+) will match value>1234 Blues What do I need to do for the match to only return 1234 Blues using "value>" in the expression (to make the search more specific)? 回答1: Although I agree with John Saunders, here is the answer to the question (or at least the one that I could come up with :) <font[^>]*?>(.*?)\s*<\/font> 来源： https://stackoverflow.com/questions/8652039/regex-match-between

Use Index Match to Return Value Using Lookup Value from Multiple Columns

由 陌路散爱 提交于 2020-01-17 06:23:20
问题 I'm trying to return a value from one column using values from a range of 3 columns. When I enter an electrical, plumbing or gas permit number into a report (D14) I want the corresponding building permit number to be entered into another cell as the file reference. The report is one worksheet and the list of permit numbers is another worksheet in the same workbook. It's one permit one report so I don't think I need anything complicated. VLOOKUP didn't work because I need to search right to

Android TabHost 实现Tab切换

由 為{幸葍}努か 提交于 2020-01-16 23:14:17
TabHost是整个Tab的容器，包含TabWidget和FrameLayout两个部分，TabWidget是每个Tab的表情(图标效果)，FrameLayout是Tab内容 实现方式有两种： 1、继承TabActivity 2、继承Activity类 方法一：继承TabActivity 从TabActivity中用getTabHost()方法获取TabHost，然后设置标签内容 布局： 1、TabHost　　　　必须设置android:id为@android:id/tabhost 2、TabWidget　　　必须设置android:id为@android:id/tabs 3、FrameLayout　 必须设置android:id为@android:id/tabcontent 这几个都是系统自带id，最好是快捷键联想生成，不要手写，这样不容易出错 XML布局文件： 1 <TabHost xmlns:android="http://schemas.android.com/apk/res/android" 2 android:layout_width="match_parent" 3 android:layout_height="match_parent" 4 android:id="@android:id/tabhost" 5 > 6 7 <LinearLayout 8

Android TabHost中实现标签的滚动以及一些TabHost开发的奇怪问题

由 ≡放荡痞女 提交于 2020-01-16 23:11:03
最近在使用TabHost的时候遇到了一些奇怪的问题，在这里总结分享备忘一下。 首先说一点TabActivity将会被FragmentActivity所替代，但是本文中却是使用的TabActivity。 下面说说本程序能够实现的功能： 实现TabHost中的标题栏能够横向滚动； 自定义标题栏的大小和样式； 自定义标题栏的分割线的样式； 下面分几步来分别实现以上的功能： 第一步，先实现一个基本的TabHost的展现 详细的说明可以在网上其它地方搜的，主要就是注意一点，控件的id的是固定的不能随便更改，并且@和id之间不能加+; Activity的代码如下： public class TabhostTestActivity extends TabActivity implements TabContentFactory { private final String[] tabTitle = { "测试Tab标签1", "测试Tab标签2", "测试Tab标签3", "测试Tab标签4", "测试Tab标签5", "测试Tab标签6", "测试Tab标签7", "测试Tab标签8", "测试Tab标签9" }; /** Called when the activity is first created. */ @Override public void onCreate(Bundle

hashtag boundaries matching regex in javascript

由 女生的网名这么多〃 提交于 2020-01-16 20:09:36
问题 I'm trying to match a set of hashtags or words in a javascript string. (#hashtag|word) almost does it, except I'd like to consider word boundaries. \b(#hashtag|word)\b doesn't match the beginning word boundary, since of course '#' is not a word character. ideally i'd like to have something like a '\b' anchor that matches hashtags. Any idea? 回答1: What about insert word boundary inside the parenths : /(#\bhashtag|\bword)\b/ 回答2: If you want to use Twitter's official regular expression for

mongo的聚合操作

对图7-1所示的数据集exampledata1，使用聚合操作实现以下功能： （1）不返回_id字段，只返回age和sex字段。 （2）所有age大于28的记录，只返回age和sex。 （3）在$match返回的字段中，添加一个新的字段“hello”，值为“world”。 （4）在$match返回的字段中，添加一个新的字段“hello”，值复制age的值。 （5）在$match返回的字段中，把age的值修改为一个固定字符串。 （6）把user.name和user.user_id变成普通的字段并返回。 （7）在返回的数据中，添加一个字段“hello”，值为“$normalstring”，再添加一个字段“abcd”，值为1。 “$match”可以筛选出需要的记录，那么如果想只返回部分字段，又应该怎么做呢？这时就需要使用关键字“$project”。 返回部分字段 首先用“$project”来实现一个已经有的功能——只返回部分字段。格式如下： collection . aggregate ([{ '$project' : {字段过滤语句}}]) 这里的字段过滤语句与“find()”第2个参数完全相同，也是一个字典。字段名为Key，Value为1或者0（需要的字段Value为1，不需要的字段Value为0）。 例如，对于图7-1所示的数据集，不返回“_id”字段，只返回age和sex字段

MySQL / PHP: catch all entries between 2 times and check against 2 other times

问题 I have a database where people can book rooms within two certain times, but there may be other people searching for an available room within the same times - or partly in the same time. Database looks like this: order | room | user | date (date-format) | from (time) | to (time) 1 123 foo 2013-04-04 12:00:00 17:00:00 The problem comes when another user searches if the room is available from f.ex 13:00 to 18:00, since I only manage to search if the room is available in the exact same time.
