  • Match Anything Except a Sub-pattern

    - by Tim Lytle
    I'd like to accomplish what this (invalid I believe) regular expression tries to do: <p><a>([^(<\/a>)]+?)<\/a></p>uniquestring Essentially match anything except a closing anchor tag. Simple non-greedy doesn't help here because `uniquestring' may very well be after another distant closing anchor tag: <p><a>text I don't <tag>want</tag> to match</a></p>random data<p><a>text I do <tag>want to</tag> match</a></p>uniquestring more matches <p><a>of <tag>text I do</tag> want to match</a></p>uniquestring So I have more tag in between the anchor tags. And I'm using the presence of uniquestring to determine if I want to match the data. So a simple non-greedy ends up matching everything from the start of the data I don't want to the end of the data I do want. I know I'm edging close to the problems regular expressions (or at least my knowledge of them) aren't good at solving. I could just through the data at an HTML/XML parser, but it is just one simple(ish) search. Is there some easy way to do this that I'm just missing?

  • IE: position two text lines on top and bottom corners in table cell?

    - by diggonce
    I have a table with dynamic data. And there is a specific line of text which should be displayed only when a user hovers over the table row. This line of text should be 'fixed' to the table cell's bottom edge. It works so far with Firefox, but fails in IE. Live code can be seen here: http://2010resolutions.org/test/index.html The text in red should be fixed to the table cell's bottom border. (They will have a fixed height and width) Any clues how to get this working in IE? Any help is appreciated. Here's the code: <style> table { width: 500px; background: gray; } td { vertical-align: top; } .wrapper { position: relative; background: green; } tr, td, .wrapper { height: 100%; padding-bottom: 0.75em; } .bottom { position: absolute; left: 0; bottom: 0; background: red; } .bottom { visibility: hidden; } tr:hover .bottom { visibility: visible; } </style> <table> <tr class="data"> <td> <div class="wrapper"> This is line 1<br /> This is line 2<br /> This is line 3<br /> <span class="bottom">Bottom line 1</span> </div> </td> <td> <div class="wrapper"> This is line 4<br /> This is line 5<br /> This is line 6<br /> <span class="bottom">Bottom line 2</span></span> </div> </td> <td> <div class="wrapper"> This is line 7<br /> This is line 8<br /> This is line 9<br /> This is line 10<br /> This is line 11<br /> This is line 12<br /> <span class="bottom">Bottom line 3</span> </div> </td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> </table>

  • using itext how to extracta string in java

    - by user2455183
    I am finding the string in between 123 and 321 and making it as bold. For that I used the Pattern to get the string before 123, text between 123 and 321 and text after 321. Could anyone please help me get all the strings between 123 and 321. Pattern p = Pattern.compile("^.*?(123)"); Matcher m = p.matcher(meredithEditorialSectionSegment); while (m.find()) { String desc = m.group(); String segDesc = (desc.substring(0, desc.length() - 3)); segmentDesc.add(new Chunk(segDesc, sectionDescriptionFont)); } descBold = meredithEditorialSectionSegment.substring(meredithEditorialSectionSegment.indexOf("123") + 3); descBold = descBold.substring(0, descBold.indexOf("321")); segmentDesc.add(new Chunk(descBold, sectionDescriptionBoldFont)); Matcher matcher = Pattern.compile("(?<=321).*").matcher(meredithEditorialSectionSegment); matcher.find(); segmentDesc.add(new Chunk(matcher.group(), sectionDescriptionFont));

  • .Net Round-trip Types

    - by Fujiy
    I making a method that generate a unique string key for some parameters. But the same key if call with same values. I just accept primitive types, string, DateTime, Guid, and Nullable(since I append types together, I can distinguish who is int and who is int?), because I can convert all to string without lost values or precision.(for float and double a use ToString("R"), to DateTime ToString("O")). Exists a easy way to know which types I can transform in strings without conflict? And how do this transform(how I said before, float, double and datetime have specific ways) Thanks

  • input URL, output contents of "view page source", i.e. after javascript / etc, library or command-li

    - by Ryan Berckmans
    I need a scalable, automated, method of dumping the contents of "view page source" (DOM) to a file. Programs such as wget or curl will non-interactively retrieve a set of URLs, but do not execute javascript or any of that 'fancy stuff'. My ideal solution looks like any of the following (fantasy solutions): cat urls.txt | google-chrome --quiet --no-gui \ --output-sources-directory=~/urls-source (fantasy command line, no idea if flags like these exist) or cat urls.txt | python -c "import some-library; \ ... use some-library to process urls.txt ; output sources to ~/urls-source" As a secondary concern, I also need: dump all included javascript source to file (a la firebug) dump pdf/image of page to file (print to file)

  • sql report link with rs:Command paramaters not opening in JSF page

  • Postfix and right-associative operators in LR(0) parsers

    - by Ian
    Is it possible to construct an LR(0) parser that could parse a language with both prefix and postfix operators? For example, if I had a grammar with the + (addition) and ! (factorial) operators with the usual precedence then 1+3! should be 1 + 3! = 1 + 6 = 7, but surely if the parser were LR(0) then when it had 1+3 on the stack it would reduce rather than shift? Also, do right associative operators pose a problem? For example, 2^3^4 should be 2^(3^4) but again, when the parser have 2^3 on the stack how would it know to reduce or shift? If this isn't possible is there still a way to use an LR(0) parser, possibly by converting the input into Polish or Reverse Polish notation or adding brackets in the appropriate places? Would this be done before, during or after the lexing stage?

  • How do I deal with connection strings in a Click-Once application?

    - by Pwninstein
    I'm thinking of building a Click-Once application, and am trying to wrap my head around how to handle the whole connection string issue. The problem is the following: I want to use EF to get data directly from each client, thus requiring each client to have a connection string configured (this is not the issue). How do I deal with clients that are not on the same domain as the SQL Server being queried? In other words, if I tried to run my app from home as opposed to from work, what should my connection string look like? Would I need to configure my SQL Server differently to allow this scenario? Thanks in advance!

  • PHP - complete url parser help

    - by Mark
    I have been trying to find an effective url parser, php's own does not include subdomain or extension. On php.net a number of users had contributed and made this: function parseUrl($url) { $r = "^(?:(?P<scheme>\w+)://)?"; $r .= "(?:(?P<login>\w+):(?P<pass>\w+)@)?"; $r .= "(?P<host>(?:(?P<subdomain>[-\w\.]+)\.)?" . "(?P<domain>[-\w]+\.(?P<extension>\w+)))"; $r .= "(?::(?P<port>\d+))?"; $r .= "(?P<path>[\w/]*/(?P<file>\w+(?:\.\w+)?)?)?"; $r .= "(?:\?(?P<arg>[\w=&]+))?"; $r .= "(?:#(?P<anchor>\w+))?"; $r = "!$r!"; // Delimiters preg_match ( $r, $url, $out ); return $out; } Unfortunately it fails on paths with a '-' and I can't for the life of me workout how to amend it to accept '-' in the path name. Thanks

  • Get the subdomain from a URL

    - by jb
    Getting the subdomain from a URL sounds easy at first. http://www.domain.example Scan for the first period then return whatever came after the "http://" ... Then you remember http://super.duper.domain.example Oh. So then you think, okay, find the last period, go back a word and get everything before! Then you remember http://super.duper.domain.co.uk And you're back to square one. Anyone have any great ideas besides storing a list of all TLDs? John

  • SimpleTest assertTags - loose matching? (for CakePHP)

    - by Arkaaito
    I'd like to use SimpleTest to set up some functionality tests for our project - in particular, we have a very busy page which has some random components and some static components, and I'd like to be able to write a simple test which only confirms the static bits (preferably only the one or two most important ones). In other words, I want to be able to leave out any tags on the page I don't care about, and write something like: $result = "<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head><title>...</title><meta .../></head><body><script type="text/javascript">...</script><div class="center-splash"><span>Welcome JohnDoe</span><p>Your progress:</p>...</div><div class="left-column">...</div><div class="right-column">...</div>...</body></html>"; $expects = array('html'=>true,'body'=>true,'div'=>array('class'=>'center_splash'),'span'=>true,'Welcome JohnDoe','/span','/div','/body','/html'); $this->assertTagsButIgnoreExtras($result, $expects); When I try this with assertTags it fails. Is there a version of assertTags which allows this - something either officially part of the SimpleTest or CakePHP project or unofficially put out under the MIT license or similar?

  • Split string into sentences based on periods

    - by rookie
    Hi all, I have written this piece of code that splits a string and stores it in a string array:- String[] sSentence = sResult.split("[a-z]\.\s+"); However, I've added the [a-z] because I wanted to deal with some of the abbreviation problem. But then my result shows up as so:- Furthermore when Everett tried to instruct them in basic mathematics they proved unresponsiv I see that I loose the pattern specified in the split function. Its okay for me to loose the period, but loosing the last letter of the word disturbs its meaning. Could some one help me with this and in addition also could someone help me with dealing with abbreviations? Like because I split the string based on periods, I do not want to loose the abbreviations. Thanks in advance

  • what is the most elegant way in ruby to remove a parameter from url?

    - by dimus
    I would like to take out a parameter from url by it's name without knowing if it is the first, middle or last parameter and reassemble url again. I guess it is not that hard to write something on my own using CGI or URI, but I imagine such functionality exists already. Any suggestions? in: http://example.com/path?param1=one&param2=2&param3=something3 out: http://example.com/path?param2=2&param3=something3

  • XPathDocument behavior with DOCTYPE declaration

    - by gliderkite
    I use XPathDocument to parse an XML file, but if there's a doctype declaration, when I initializes a new instance of the XPathDocument class passing the path of the file, that contains the XML data, to its constructor, my application tries to connect to internet (probably to verify the correctness of the XML data) and remains blocked for a long period of time. This does not occur if I delete the doctype declaration from the XML file. XmlDocument.Load method has the same behavior. How can I fix this problem? Thanks.
