am using Boilerpipe in my application, and when am trying to extract the content using ArticleExtractor am getting plane text only, all the html formating has been removed, so am trying with HtmlHighlighter. but the process method of HtmlHighlighter fails for certain urls.
is there any option to use html string to pass to this method? can anybody explain?
You can use IKVM to convert the Boilerpipe jar into a new DLL to use in your .NET aplications. I am using this approach and works fine when sending html thrown the different boilerpipe methods.
If the page content that you are trying to access is loaded by javascript, a simple http request cant handle such information.
First you need to get the result html after the javascript changes, and then give it to boilerpipe.
I am trying to parse some html to switch out values of various element attributes. I decided that the most reliable way to parse the html was to use an xml parser (msxml.)
The problem is that the html I'm trying to parse contains attribute like:
<param name="flashvars" value="autoplay=false&brand=embed&cid=97%2Ftest&locale=en_US"/>
Which causes the xml parser to blow up. I figured out that I need to server.htmlencode() the value attribute in order for the xml parser to load it properly. How do I approach this?
I feel like the problem is a vicious circle. I couldn't use regex's because html is not regular enough, and now I can't use xml parsers because the html isn't "well formed"
help. How do I approach this issue? I want to be able to change attribute values with a vbscript.
Is your HTML well formed? If so you could simply use an XML DomDocument. Use XPath to find the attributes you want to replace.
You can actually use JScript serverside as well in ASP, whicdh might give you access to HTMLDom libraries you could use.
You should probably have a look at one of the libraries for cleaning up HTML, something like HTML Tidy http://www.w3.org/People/Raggett/tidy/
Your main problem is you need to do a replace on the ampersands, they need to be & in well formed XML/XHTML.
Is there a simple way of making the static content of an .aspx page multi-lingual? Resource files are nice for controls but it's quite hard and annoying to write big chunks of html in them. Any easier ways?
Make properties in resources files and use them, .NET automatically finds the correct resource file, also just make sure so that the property name is same in all the resource files, so it will replace the property value in .aspx page with the value in the resource file.
Don't code html markup in resource file, have the html markup in the .aspx page itself, just get the essential values from resource files.
Just to reiterate what Mahesh said: do NOT put markup in the resource files, just put the static content into them.
If you need to serve different views based on culture, consider doing something else. For example, if you're using MVC you could write a view engine that return the correct markup for each culture.
#ciscoheat what you say is correct, LOCALIZE control is the right thing to use for big chunk of data.
I have a lot of html pages, but I don't know how to display them through the asp.net mvc view.
I buid a view as my template and use asp.net mvc to insert html into the template and then render it.
But the question is that I must use FileStream to read the raw html-based files into memroy and then put it into view template, like ViewData["content"] = ???.
I just want to know if there are some other better ways to render static html files to the browser.
Did i describe the question clearly?
I guess you could do something like this:
using(var file = new StreamReader(htmlFileName))
{
return Content(file.ReadToEnd());
}
Note that the mime type automatically defaults to text/html, but you could optionally specify which mime type headers should be sent by supplying the type as an additional argument to the Content method.
I guess you also can point a iframe element from HTML to the target file url directly.
Alternatively you could write your own ActionResult that writes the contents of the file to Response.Output (could potentially avoid loading the entire file into memory at once albeit it might not be a big issue).
I have a legacy application that I needed to implement a configuration page for to change text colors, fonts, etc.
This applications output is also replicated with a PHP web application, where the fonts, colors, etc. are configured in a style sheet.
I've not worked with CSS previously.
Is there a programatic way to modify the CSS and save it without resorting to string parsing or regex?
The application is VB6, but I could write a .net tool that would do the css manipulation if that was the only way.
You don't need to edit the existing one. You could have a new one that overrides the other -- you include this one after the other in your HTML. That's what the "Cascading" means.
It looks like someone's already done a VB.NET CSS parser which is F/OSS, so you could probably adapt it to your needs if you're comfortable with the license.

One hack is to create a PHP script that all output is passed through, which then replaces certain parts of CSS with configurable alternatives. If you use .htaccess you can make all output go through the script.
the best way i can think of solving this problem is creating an application that will get some values ( through the URL query ) and generate the appropriate css output based on a css templates
Check this out, it uses ASP.NET and C#.
In my work with the IE control (shadocvw.dll), it has an interesting ability to let you easily manage the CSS of a page and show the effects of modified CSS on a page in realtime. I've never dealt with the details of such implementations myself, but I recommend that as a possible solution worth looking at. Seeing as pretty much everyone is on IE 6 or later nowadays, you can skip the explanations about handling those who only have IE 5,4,3 or 2 installed.
Maybe the problem's solution, which is most simple for the programmer and a user is to edit css via html form, maybe. I suppose, to create css-file, which would be "default" or "standart" for this application, and just to read it, for example, by perl script, edit in html and to write it down. Here is just the simple example.
In css-file we have string like:
border-color: #008a77;
we have to to read this string, split it up, and send to a file, which will write it down. Get something like this in Perl:
tr/ / /s;
($vari, $value) = split(/:/, _$);
# # While you read file, you can just at the time to put this into html form
echo($vari.":<input type = text name = ".$vari." value = ".$value.">");
And here it is, you've got just simple html-form-data, you just shoul overwrite your css-file with new data like this:
...
print $vari[i].": ".$value.";\n";
...
and voila - you've got programmatical way of changing css. Ofcourse, you have to make it more universal, and more close to your particular problem.
Depending on how technically oriented your CSS editors are going to be, you could do it very simply by loading the whole thing up into a TextEdit field to let them edit it - then write it back to the file.
Parsing and creating an interface for all the possibilities of CSS would be an astronomical pain. :-)
