问题 I have multiple .txt files in a directory. Here is a sample of one of my .txt files: kkkkk; select xx("xE'", PUT(xx.xxxx.),"'") jdfjhf:jhfjj from xxxx_x_xx_L ; quit; /* 1.xxxxx FROM xxxx_x_Ex_x */ proc sql; ("TRUuuuth"); hhhjhfjs as fdsjfsj: select * from djfkjd to jfkjs ( SELECT abc AS abc1, abc_2_ AS efg, abc_fg, fkdkfj_vv, jjsflkl_ff, fjkdsf_jfkj FROM &xxx..xxx_xxx_xxE where ((xxx(xx_ix as format 'xxxx-xx') gff &jfjfsj_jfjfj.) and (xxx(xx_ix as format 'xxxx-xx') lec &jgjsd_vnv.)) ); jjjjjj

问题 I would like to catch all "dev" tags and their respective content, through php preg_match_all() but can't get the nested ones. data: <dev>aaa</dev> <dev>bbb</dev> <dev> ccc <dev>ddd</dev> </dev> my expression so far: |<dev>(.*)</dev>|Uis thanks, for your help, b. 回答1: Don’t use regular expressions for parsing. Use a real parser like DOMDocument or SimpleXML: $xml = simplexml_load_string('<root>'.$str.'</root>'); 回答2: You need to have a recursive matching pattern: /<dev>(.*|(?R))<\/dev>/i That

问题 I have an issue appending or in fact printing anything after this block of code: reversedPriv = [52,27,13,6,3,2] array= [9] var = 0 numA = [] for i in array: for j in reversedPriv: while var!= j: if j < i: var = var + j numA.append(j) numA.sort() print(numA) I am expecting it to append [3,6] to numA and print but it currently does nothing. Is there some condition for the while loop that I'm overlooking? The point of the code is to find which elements in 'reversedPriv' sum up to each element

问题 I am writing a WebService that is supposed to convert DataSet into XML. My DataSet is actually list of hotels with categories. Each hotel can belong to one or more categories. I followed an example from HERE and it works well except I don't get result that I would like. This is what I get: (example 1) <hotels> <hotel> <name>Hilton Resort</name> <category> <catname>Hotel</catname> </category> <category> <catname>Resort</catname> </category> <category> <catname>Golf & Spa</catname> </category>

问题 I am a newbie to R and I have problem splitting a very large data frame into a nested list. I tried to look for help on the internet, but I was unsuccessful. I have a simplified example on how my data are organized: The headers are: 1 "station" (number) 2. "date.str" (date string) 3. "member" 4. "forecast time" 5. "data" I am not sure my data example will show up rightly, but if so, it look like this: 1. station date.str member forecast.time data1 2. 6019 20110805 mbr000 06 77 3. 6031

问题 I researched this quite a bit, but couldn't find a working example how to match nested html tags with attributes. I know it is possible to match balanced/nested innermost tags without attributes (for example a regex for and would be #<div\b[^>]*>(?:(?> [^<]+ ) |<(?!div\b[^>]*>))*?</div> #x). However, I would like to see a regex pattern that finds an html tag pair with attributes. Example: It basically should match <div class="aaa"> **<div class="aaa">** <div> <div> </div> **</div>** </div>

问题 I have been getting frustrated with this code for hours now and I just have to bow and ask for some help. I am trying to get these nested if's to work but it is either returning nothing and I am getting no errors or it is going to the end of the coding where it should have stopped beforehand. These inputs are all from groups radio buttons and the reason for the order is so that they would filter through from the simplest to the more complex once it gets to the function that is being called. I

问题 This is what I get: <ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace"> <ex:A Type="lorem">ipsum</ex:A> </ex:test> This is what I want: (Note that the Type-attribute is prefixed with ex.) <ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace"> <ex:A ex:Type="lorem">ipsum</ex:A> </ex:test> This is my code: [XmlType(Namespace = "http://www.example.com/namespace")] [XmlRoot("ex", Namespace = "http://www.example.com/namespace")] public class

问题 Is it possible to put ListBoxes inside of SimpleListWalkers ?
