python - Scrapying a table with <p style="position -


i scrape page have several paragraph tags :

 <p style="position:absolute;top:110px;left:65px">

and have 4 elements in each line following :

<p style="position:absolute;top:110px;left:65px"><span style="virtical-align:top;font-size:9px;font-family:gothictext;color:#000000;letter-spacing:0.00000px;stringwidth:86px;">information a_110</span></p>  <p style="position:absolute;top:110px;left:173px"><span style="virtical-align:top;font-size:9px;font-family:gothictext;color:#000000;letter-spacing:1.64571px;stringwidth:115px;">information b_110</span></p> <p style="position:absolute;top:110px;left:403px"><span style="virtical-align:top;font-size:9px;font-family:gothictext;color:#000000;letter-spacing:1.55520px;stringwidth:194px;">information c_110</span></p> <p style="position:absolute;top:110px;left:814px"><span style="virtical-align:top;font-size:9px;font-family:gothictext;color:#000000;letter-spacing:1.59158px;stringwidth:151px;"> information d_110</span></p>  <p style="position:absolute;top:110px;left:1080px"><span style="virtical-align:top;font-size:9px;font-family:gothictext;color:#000000;letter-spacing:0.00000px;stringwidth:36px;"> information e_110</span></p>

i stack information a_110, b_110, c_110, d_110 table each line.

what far: record pages exact position (left :1080px, etc.) , xparse each position extract information. problem don't detect automatically position (top:110px;left:1080px instance), need enter manually.

the drawback of approach can omit data points (for instance if position becomes top:111px;left:1080px instead of top:110px;left:1080px).

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
