  • How do you automap List<float> or float[] with Fluent NHibernate?

    - by Tom Bushell
    Having successfully gotten a sample program working, I'm now starting to do Real Work with Fluent NHibernate - trying to use Automapping on my project's class heirarchy. It's a scientific instrumentation application, and the classes I'm mapping have several properties that are arrays of floats e.g. private float[] _rawY; public virtual float[] RawY { get { return _rawY; } set { _rawY = value; } } These arrays can contain a maximum of 500 values. I didn't expect Automapping to work on arrays, but tried it anyway, with some success at first. Each array was auto mapped to a BLOB (using SQLite), which seemed like a viable solution. The first problem came when I tried to call SaveOrUpdate on the objects containing the arrays - I got "No persister for float[]" exceptions. So my next thought was to convert all my arrays into ILists e.g. public virtual IList<float> RawY { get; set; } But now I get: NHibernate.MappingException: Association references unmapped class: System.Single Since Automapping can deal with lists of complex objects, it never occured to me it would not be able to map lists of basic types. But after doing some Googling for a solution, this seems to be the case. Some people seem to have solved the problem, but the sample code I saw requires more knowledge of NHibernate than I have right now - I didn't understand it. Questions: 1. How can I make this work with Automapping? 2. Also, is it better to use arrays or lists for this application? I can modify my app to use either if necessary (though I prefer lists). Edit: I've studied the code in Mapping Collection of Strings, and I see there is test code in the source that sets up an IList of strings, e.g. public virtual IList<string> ListOfSimpleChildren { get; set; } [Test] public void CanSetAsElement() { new MappingTester<OneToManyTarget>() .ForMapping(m => m.HasMany(x => x.ListOfSimpleChildren).Element("columnName")) .Element("class/bag/element").Exists(); } so this must be possible using pure Automapping, but I've had zero luck getting anything to work, probably because I don't have the requisite knowlege of manually mapping with NHibernate. Starting to think I'm going to have to hack this (by encoding the array of floats as a single string, or creating a class that contains a single float which I then aggregate into my lists), unless someone can tell me how to do it properly. End Edit Here's my CreateSessionFactory method, if that helps formulate a reply... private static ISessionFactory CreateSessionFactory() { ISessionFactory sessionFactory = null; const string autoMapExportDir = "AutoMapExport"; if( !Directory.Exists(autoMapExportDir) ) Directory.CreateDirectory(autoMapExportDir); try { var autoPersistenceModel = AutoMap.AssemblyOf<DlsAppOverlordExportRunData>() .Where(t => t.Namespace == "DlsAppAutomapped") .Conventions.Add( DefaultCascade.All() ) ; sessionFactory = Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile) .ShowSql() ) .Mappings(m => m.AutoMappings.Add(autoPersistenceModel) .ExportTo(autoMapExportDir) ) .ExposeConfiguration(BuildSchema) .BuildSessionFactory() ; } catch (Exception e) { Debug.WriteLine(e); } return sessionFactory; }

  • SNMP based network discovery (switches), device (ports on switches) power management

    - by SaM
    In a enterprise network, what would be the right way to generate a list of switches (SNMP managed) Is it reasonable to ask the organization to supply a list such as this: Switch name IP Address of switch Location SNMP community strings Or are there standard ways to run discovery scans - UDP broadcasts? After having generated a repository such as the above; given a single switch, how to query it for the list of all devices attached to it? Finally, how to selectively power down/power up ports? (remotely - using SNMP) Platform is going to be .NET based (C#) and the library being used is SharpSNMP

  • Calculate a set of concatenated sets of n sets

    - by Andras Zoltan
    Okay - I'm not even sure that the term is right - and I'm sure there is bound to be a term for this - but I'll do my best to explain. This is not quite a cross product here, and the order of the results are absolutely crucial. Given: IEnumerable<IEnumerable<string>> sets = new[] { /* a */ new[] { "a", "b", "c" }, /* b */ new[] { "1", "2", "3" }, /* c */ new[] { "x", "y", "z" } }; Where each inner enumerable represents an instruction to produce a set of concatenations as follows (the order here is important): set a* = new string[] { "abc", "ab", "a" }; set b* = new string[] { "123", "12", "1" }; set c* = new string[] { "xyz", "xy", "x" }; I want to produce set ordered concatenations as follows: set final = new string { a*[0] + b*[0] + c*[0], /* abc123xyz */ a*[0] + b*[0] + c*[1], /* abc123xy */ a*[0] + b*[0] + c*[2], /* abc123x */ a*[0] + b*[0], /* abc123 */ a*[0] + b*[1] + c*[0], /* abc12xyz */ a*[0] + b*[1] + c*[1], /* abc12xy */ a*[0] + b*[1] + c*[2], /* abc12x */ a*[0] + b*[1], /* abc12 */ a*[0] + b*[2] + c*[0], /* abc1xyz */ a*[0] + b*[2] + c*[1], /* abc1xy */ a*[0] + b*[2] + c*[2], /* abc1x */ a*[0] + b*[2], /* abc1 */ a*[0], /* abc */ a*[1] + b*[0] + c*[0], /* ab123xyz */ /* and so on for a*[1] */ /* ... */ a*[2] + b*[0] + c*[0], /* a123xyz */ /* and so on for a*[2] */ /* ... */ /* now lop off a[*] and start with b + c */ b*[0] + c*[0], /* 123xyz */ /* rest of the combinations of b + c with b on its own as well */ /* then finally */ c[0], c[1], c[2]}; So clearly, there are going to be a lot of combinations! I can see similarities with Numeric bases (since the order is important as well), and I'm sure there are permutations/combinations lurking in here too. The question is - how to write an algorithm like this that'll cope with any number of sets of strings? Linq, non-Linq; I'm not fussed. Why am I doing this? Indeed, why!? In Asp.Net MVC - I want to have partial views that can be redefined for a given combination of back-end/front-end culture and language. The most basic of these would be, for a given base view View, we could have View-en-GB, View-en, View-GB, and View, in that order of precedence (recognising of course that the language/culture codes could be the same, so some combinations might be the same - a Distinct() will solve that). But I also have other views that, in themselves, have other possible combinations before culture is even taken into account (too long to go into - but the fact is, this algo will enable a whole bunch of really cool that I want to offer my developers!). I want to produce a search list of all the acceptable view names, iterate through the whole lot until the most specific match is found (governed by the order that this algo will produce these concatenations in) then serve up the resolved Partial View. The result of the search can later be cached to avoid the expense of running the algorithm all the time. I already have a really basic version of this working that just has one enumerable of strings. But this is a whole different kettle of seafood! Any help greatly appreciated.

  • Using a redirect of any form to remove a query string with Apache

    - by Bart B
    Because of the silly way iTunes works the only way to update the URL for a feed is by setting up a permanent redirect from the old feed to the new. This seems easy, but I've hit a snag. The old URL ended in /?feed=rss2, the new URL is just a file, so it ends in podcast.xml. When I redirected from the old URL to the new, iTunes picked up the new URL BUT, WITH the query string, so now the URL ends in podcast.xml?feed=rss2. This is allowing listers to download the show - which is good, but causing some other problems. Is there any possible way to set up a permanent redirect that will redired podcast.xml?feed=rss2 to just podcast.xml? Mod_Rewrite seems to just pass through query strings, so I'm at a loss! Bart.

  • An "elegant" way of identifying a field?

    - by Alix
    Hi. I'm writing a system that underlies programmer applications and that needs to detect their access to certain data. I can mostly do so with properties, like this: public class NiceClass { public int x { get; set; } } Then I go in and tweak the get and set accessors so that they handle the accesses appropriately. However this requires that the users (application programmers) define all of their data as properties. If the users want to use pre-existing classes that have "normal" fields (as opposed to properties), I cannot detect those accesses. Example: public class NotSoNiceClass { public int y; } I cannot detect accesses to y. However, I want to allow the use of pre-existing classes. As a compromise the users are responsible for notifying me whenever an access to that kind of data occurs. For example: NotSoNiceClass notSoNice; ... Write(notSoNice.y, 0); // (as opposed to notSoNice.y = 0;) Something like that. Believe me, I've researched this very thoroughly and even directly analysing the bytecode to detect accesses isn't reliable due to possible indirections, etc. I really do need the users to notify me. And now my question: could you recommend an "elegant" way to perform these notifications? (Yes, I know this whole situation isn't "elegant" to begin with; I'm trying not to make it worse ;) ). How would you do it? This is a problem for me because actually the situation is like this: I have the following class: public class SemiNiceClass { public NotSoNiceClass notSoNice { get; set; } public int z { get; set; } } If the user wants to do this: SemiNiceClass semiNice; ... semiNice.notSoNice.y = 0; They must instead do something like this: semiNice.Write("notSoNice").y = 0; Where Write will return a clone of notSoNice, which is what I wanted the set accessor to do anyway. However, using a string is pretty ugly: if later they refactor the field they'll have to go over their Write("notSoNice") accesses and change the string. How can we identify the field? I can only think of strings, ints and enums (i.e., ints again). But: We've already discussed the problem with strings. Ints are a pain. They're even worse because the user needs to remember which int corresponds to which field. Refactoring is equally difficult. Enums (such as NOT_SO_NICE and Z, i.e., the fields of SemiNiceClass) ease refactoring, but they require the user to write an enum per class (SemiNiceClass, etc), with a value per field of the class. It's annoying. I don't want them to hate me ;) So why, I hear you ask, can we not do this (below)? semiNice.Write(semiNice.notSoNice).y = 0; Because I need to know what field is being accessed, and semiNice.notSoNice doesn't identify a field. It's the value of the field, not the field itself. Sigh. I know this is ugly. Believe me ;) I'll greatly appreciate suggestions. Thanks in advance! (Also, I couldn't come up with good tags for this question. Please let me know if you have better ideas, and I'll edit them)

  • apply seach criteria to whole cells

    - by Tom
    I am trying to use MATCH() and/or LOOKUP() in LibreOffice Calc. I have the "Search criteria = and < must apply to whole cells" and the "Enable regular expressions in formulas" options selected. The item I am looking for is a multi word string. How do I provide a search criteria as a cell reference (E3) in to LOOKUP(E3, B1:B20, C1:C20) and have it match the value in B1:B20 EXACTLY? Right now it is matching partial strings rather than matching the cell values exactly.

  • How to reset mac PRAM through the command line in Lion/Mountain Lion?

    - by boneyjellyfish
    I'm trying to write a script to automate a PRAM reset and I've seen a lot of old guides that tell me to use the following command to reset the Mac's PRAM via the terminal: nvram boot-args="-p -r" But this command doesn't seem to work anymore, at least not on any of the computers I've tried it on. I'm trying to find a more up-to-date list of available boot-args and I was able to find this question about boot-args strings but there doesn't seem to be anything in there or any of the links about resetting the pram. Any ideas?

  • eXML-PARSER output contains unwanted hash references

  • 255 Character limit on VLOOKUP

    - by zod
    Using excel 2003, the formula: =VLOOKUP(D1 ,A1:B135, 2) fails if the length of D1 exceeds 255 characters (i.e. the list has some text longer then 255 characters, D1 has the same text value, and VLOOKUP returns #VALUE!). MATCH seems to suffer from the same character limit. I cannot find any official confirmation of these limits, for example here: http://office.microsoft.com/en-us/excel-help/vlookup-HP005209335.aspx or here: http://office.microsoft.com/en-us/excel-help/excel-specifications-and-limits-HP005199291.aspx?CTT=3 I know that excel has a 255 limit on the length of text used in formulae, but it suggests connate should work (it does not in this case, and I am not using strings in the formula, but referencing another cell). Can somebody confirm that these limit exist (it is always possible I am doing something else wrong)? More importantly, does anyone know of a way around them? Thanks

  • sql and web encoding problem

    - by Marki
    Guys, I've got an encoding problem I believe. I have upgraded from phpBB2 to phpBB3. The old databases were in latin1, the new ones have utf8 encoding. Already during the upgrade process some rows of the DB were only read partly into the new version, because of strange characters as it turned out. When I use PHP's mb_convert_encoding() function to convert those strings to UTF8 they end up e.g. as 0x0093, i.e. they must have been some kind of double quotes. Even after doing this conversion, they still show up as 0x0093 in the browser (the squares with 0093 in them when the browser does not know what to display). Can someone explain the problem here? I'm a little confused and afraid I don't see all the dependencies that need to work to have the correct encodings and the correct display thereof...

  • Wireless Keyboard Intermittent Failure to Type and Added Characters

    - by Kashif
    My keyboard has been acting up from time to time. It's wireless so this may be a wireless issue. What happens is I will be typing and then all of a sudden it seems to stop responding. If I type out this sentence it may show up like so If I ttennnnnnnnn it may ssssssp so While typing that sentence I may have to mash on a key repeatedly to get it to type. The resulting strings of letters seem to be coming as if the keyboard buffer cannot keep up. It's so weird. If I take the USB tranceiver and yank it out then plug it back in, Voila! Problem solved. I did the battery check so that's not a problem. Any suggestions? My keyboard is the Logitech MX3200

  • Strange IIS/Asp.net Exception Message

    - by Element
    I have a standard asp.net 2.0 application running on IIS 6. I have noticed some strange exception messages in the logs. They seem to be caused by random spam bots trying to submit forms. They are strange because the request string is huge and all the exception details in the event manager are messed up, they have been replaced with %21,%22, etc.. as seen in the screen shot. Is this some kind of exploit or just a bug in the asp.net exception handler/logger ? UPDATE: I traced the requests that are causing this strange log event to a bug in IE8 that causes it to request scriptresource.axd?d={html from page} as described in these links: MS Connect SO - Invalid Webresource.axd SO - IE8 Dropping Memory Pages I am still not sure why these requests would break the IIS log event like seen above, they are just long strings of jiberish being sent to the server, maybe someone reading this can shed some light on it.

    I am trying to process some data in Calc. One of the steps involve finding if a certain string is part of one of the column. I tried using FIND and SEARCH functions. Both behave in the same way and I am not getting correct results. E.g. Say I have following strings in Column A NY SF LON CAN US and am trying to put following formula in column C =SEARCH("NY",A2) The result is - cell C2 will have 1 (which is correct) but if the same formula is copied to other cells in column C - it gives me "#VALUE!" error and I am unable to find out why ?

  • reading Twitter API with JSON framework

    - by iPixFolio
    Hi, I'm building a twitter reader into an app. I'm using this JSON library to parse the twitter API. I'm seeing some odd results on certain messages. I know that the Twitter API returns results in UTF8 format. I'm wondering if I'm doing something wrong when reading the JSON parsed fields. My code is spread out across multiple classes so it's hard to give a concise code drop with the symptoms, but here's what I've got: I am using ASIHTTP for async HTTP processing. Here is processing a response from ASIHTTP: ... NSMutableString* tempString = [[NSMutableString alloc] initWithString:[request responseString]]; NSError *error; SBJSON *json = [[SBJSON alloc] init]; id JSONresponse = [json objectWithString:tempString error:&error]; [tempString release]; [json release]; if (JSONresponse) { self.response = JSONresponse; ... self.response holds the JSON representation of the result from the Twitter call. Now, I will take the JSON response and write each tweet into a container object (Tweet). in the following code, the response from above is referenced as request.response: ... // save list of albums to local cache for (NSDictionary* response in request.response) { Tweet* tweet = [[Tweet alloc] init]; tweet.text = [response objectForKey:@"text"]; tweet.id = [response objectForKey:@"id"]; tweet.created = [response objectForKey:@"created_at"]; [Tweet addTweet:tweet]; [tweet release]; } ... at this point, I have a container holding the tweets. I'm only keeping 3 fields from the tweet: "id", "text", and "created_at". the "text" field is the problem field. To display the tweets, I build an HTML page from the container of tweets, like this: ... Tweet* tweet = nil; for (int i = 0; i < [Tweet tweetCount]; i++) { tweet = [Tweet tweetAtIndex:i]; [html appendString:@"<div class='tweet'>"]; [html appendFormat:@"<div class='tweet-date'>%@</div>", tweet.created ]; [html appendFormat:@"<div class='tweet-text'>%@</div>", tweet.text ]; [html appendString:@"</div>"]; } ... In another routine, I save the HTML page to a temp file. if (html && [html length] > 0 ) { NSString* uniqueString = [[NSProcessInfo processInfo] globallyUniqueString]; NSString* filename = [NSString stringWithFormat:@"%@.html", uniqueString ]; filename = [tempDir stringByAppendingPathComponent:filename]; NSError* error = nil; [html writeToFile:filename atomically:NO encoding:NSUTF8StringEncoding error:&error]; ... I then create a URLRequest from the file and load it into an UIWebview: NSURL* url = [NSURL fileURLWithPath:filename]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; ... At this point, I can see the tweets in a browser window. some of the tweets will show invalid characters like this: iPhone 4 ad spoofed with Glee’s Jane Lynch ... Glee’s should be Glee's Can anybody shed any light on what I'm doing wrong and offer suggestions on how to fix? basically, to summarize: I'm reading a UTF8 feed with JSON I write the UTF8 strings into an HTML file I display the HTML file with UIWebview. some of the UTF8 strings are not properly decoded. I need to know where to decode them and how to do it. thanks! Mark

  • Pure JSP without mixing HTML, by writing html as Java-like code

    - by ADTC
    Please read before answering. This is a fantasy programming technique I'm dreaming up. I want to know if there's anything close in real life. The following JSP page: <% html { head { title {"Pure fantasy";} } body { h1 {"A heading with double quote (\") character";} p {"a paragraph";} String s = "a paragraph in string. the date is "; p { s; new Date().toString(); } table (Border.ZERO, new Padding(27)) { tr { for (int i = 0; i < 10; i++) { td {i;} } } } } } %> could generate the following HTML page: <html> <head> <title>Pure fantasy</title> </head> <body> <h1>A heading with double quote (") character</h1> <p>a paragraph</p> <p>a paragraph in string. the date is 11 December 2012</p> <table border="0" padding="27"> <tr> <td>0</td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> <td>6</td> <td>7</td> <td>8</td> <td>9</td> </tr> </table> </body> </html> The thing about this fantasy is it reuses the same old Java programming language technique that enable customized keywords used in a way similar to if-else-then, while, try-catch etc to represent html tags in a non-html way that can easily be checked for syntactic correctness, and most importantly can easily be mixed up with regular Java code without being lost in a sea of <%, %>, <%=, out.write(), etc. An added feature is that strings can directly be placed as commands to print out into generated HTML, something Java doesn't support (where pure strings have to be assigned to variables before use). Is there anything in real life that comes close? If not, is it possible to define customized keywords in Java or JSP? Or do I have to create an entirely new programming language for that? What problems do you see with this kind of setup? PS: I know you can use HTML libraries to construct HTML using Java code, but the problem with such libraries is, the source code itself doesn't have a readable HTML representation like the code above does - if you get what I mean.

    Im trying to extract certain data from a cell and trying to put it somewhere else within the same cell. Any suggestions? EDIT I have several text strings in ONE cell (a date, a part number and a color). The format looks like this 100906 PBO5 BLUE. The date is always the same number of characters but the part number could be 2, 3 or 4 characters. I want to move the date to the position after the color so it looks like this PBO5 BLUE 100906. I have over 1,000 records so I don’t want to do this manually.

  • Replacing hyperlinks in Apache2 ProxyPass

    - by Jeroen
    I am using Apache2 with mod proxy on Ubuntu 12.04 as a reverse proxy to some back-end server: <VirtualHost *:80> ProxyPass / http://somewhere.com/mysite ProxyPassReverse / http://somewhere.com/mysite ServerName www.mysite.nl ServerAlias mysite.nl *.mysite.nl </VirtualHost> However, unfortunately the back-end server has some internal links hardcoded; e.g. a link to somewhere else in the site has <a href="http://somewhere.com/mysite/something"> instead of just <a href="something.png">. Is there a way I can use Apache to replace strings in the body as served by the backend before passing it back to the client? E.g replace all instances of "http://somewhere.com/site/" with "http://mysite.nl/" ? I know nginx or so is better as a reverse proxy, but the server is hosting other stuff so port 80 needs to be Apache2.

  • Trying to get a better understanding of SelectedValuePath and IsSynchronizedWithCurrentItem

    The following XAML produces a run-time Binding error when I click on an item in the ListBox: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="WpfApplication1.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <x:Array x:Key="strings" Type="{x:Type sys:String}"> <sys:String>one</sys:String> <sys:String>two</sys:String> <sys:String>three</sys:String> <sys:String>four</sys:String> </x:Array> </Window.Resources> <Grid> <ListBox DataContext="{StaticResource strings}" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}" SelectedValuePath="{Binding /Length}"> <ListBox.ItemTemplate> <DataTemplate> <Grid> <Grid.Resources> <Style TargetType="{x:Type Label}"> <Setter Property="Background" Value="Yellow"/> <Setter Property="Margin" Value="0,0,4,0"/> <Setter Property="Padding" Value="0"/> </Style> </Grid.Resources> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <!-- Row 0 --> <Label Grid.Column="0" Grid.Row="0">String:</Label> <TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding}"/> <!-- Row 1 --> <Label Grid.Column="0" Grid.Row="1">Length:</Label> <TextBlock Grid.Column="1" Grid.Row="1" Text="{Binding Length, Mode=Default}"/> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> </Window> This is the run-time Binding error message: System.Windows.Data Error: 39 : BindingExpression path error: '3' property not found on 'object' ''String' (HashCode=1191344027)'.

What is wrong with my SelectedValuePath Binding syntax? Are there any related issues with IsSynchronizedWithCurrentItem?

  • Help with Apache rewriteengine rules

    - by Vinay
    Hello - I am trying to write a simple rewrite rule using the rewriteengine in apache. I want to redirect all traffic destined to a website unless the traffic originates from a specific IP address and the URI contains two specific strings. RewriteEngine On RewriteLog /var/log/apache2/rewrite_kudithipudi.log RewriteLogLevel 1 RewriteCond %{REMOTE_ADDR} ^199\.27\.130\.105 RewriteCond %{REQUEST_URI} !/StringOne [NC, OR] RewriteCond %{REQUEST_URI} !/StringTwo [NC] RewriteRule ^/(.*) http://www.google.com [R=302,L] I put these statements in my virtual host configuration. But the rewriteengine seems to be redirect all requests, whether they match the condition or not. Am I missing something? Thank you. Vinay.

  • PHP - DOM class - numbered entities and encodings problem

    - by user343607
    Hi guys, I'm having some difficult with PHP DOM class. I am making a sitemap script, and I need the output of $doc-saveXML() to be like <?xml version="1.0" encoding="UTF-8"?> <root> <url> <loc>http://www.somesite.com/servi&#xE7;os/redesign</loc> </url> </root> or <?xml version="1.0" encoding="UTF-8"?> <root> <url> <loc>http://www.somesite.com/servi&#231;os/redesign</loc> </url> </root> but I am getting: <?xml version="1.0" encoding="UTF-8"?> <root> <url> <loc>http://www.somesite.com/servi&amp;#xE7;os/redesign</loc> </url> </root> This is the closet I could get, using a replace named to numbered entities function. I was also able to reproduce <?xml version="1.0" ?> <root> <url> <loc>http://www.somesite.com/servi&amp;#xE7;os/redesign</loc> </url> </root> But without the encoding specified. The best solution (the way I think the code should be written) would be: <?php $myArray = array(); // do some stuff to populate the with URL strings $doc = new DOMDocument('1.0', 'UTF-8'); // here we modify some property. Maybe is the answer I am looking for... $urlset = doc->createElement("urlset"); $urlset = $doc->appendChild($urlset); foreach($myArray as $address) { $url = $doc->createElement("url"); $url = $urlset->appendChild($url); $loc = $doc->createElement("loc"); $loc = $url->appendChild($loc); $valueContent = $doc->createTextNode($value); $valueContent = $loc->appendChild($address); } echo $doc->saveXML(); ?> Notes: Server response header contains charset as UTF-8; PHP script is saved in UTF-8; URLs read are UTF-8 strings; Above script contains encoding declaration on DOMDocument constructor, and does not use any convert functions, like htmlentities, urlencode, utf8_encode... I've tried changing the DOMDocument properties DOMDocument::$resolveExternals and DOMDocument::$substituteEntities values. None combinations worked. And yes, I know I can made all process without specifying the character set on DOMDocument constructor, dump string content into a variable and make a very simple string substitution with string replace functions. This works. But I would like to know where I am slipping, how can this be made using native API's and settings, or even if this is possible. Thanks in advance.
