I have xml file with tables in it and i want to retrieve the TD value and save it inside variable using TCPDF.
any help would be great.
Regards
You have two issues, one: retrieve the td information, two: put inside the pdf.
To get the info of the td use simpleXML http://php.net/manual/es/book.simplexml.php, with this tool you can get the info of every tag in the xml.
Now, when you have this information, you can put this inside the pdf with tcpdf with Cell() function. Read the documentation of tdpdf if you have problems.
Other solution: If the xml has html, you can put the html inside the pdf with WriteHtml() function.

The value in the editor is formatted only on the client side but when the value is sent to the database it is saved without the formatting.
How to save both the code and the formatting properties so that they both can be retrieved during display of the code snippet
Are you using raw action? If not, then read it.
I was using another editor (probably codemirror) and I saved the text in it to database in <pre> </pre> tag and then it would save as a string of html but later render properly too. Go through documentation of ace-editor. It must have a similar solution.
pre tag gives me this here:
Gems for ace-editor:
gem 'jquery-ace-rails'
gem 'ace-rails-ap'
I am knocking together a quick debugging view of a backend, as a small set of admin HTML pages (driven by angulardart, but not sure that is critical).
I get back from my XHR call a complex JSON object. I want to see that on the HTML page formatted nicely. It doesn't have to be a great implementation, as its just a debug ui, but the goal is to format the object instead of having it be one long string with no newlines.
I looked at trying to pretty print JSON in dart then putting that inside <pre></pre> tags, as well as just dumping the dart Map object to string (again, inside or not inside <pre></pre> tags. But not getting to where I want.
Even searched pub for something similar, such as a syntax highlighter that would output html, but didn't find something obvious.
Any recommendations?
I think what you're looking for is:
Format your JSON so it's readable
Have syntax highlight
For 1 - This can be done with JsonEncoder with indent
For 2 - You can use the JS lib called HighlightJs pretty easily by appending your formatted json into a marked-up div. (See highlightjs' doc to see what I mean)
I want to use apache tika to extract html text and css class names so that I can build a poi spreadsheet. I can get the text but how do I extract css class names?
Thank You In Advance ...
Try creating a custom handler. If you override the startElement method you'll have access to the html attributes. Inheriting from BodyContentHandler should be pretty simple as a starting point. If the element you're targeting isn't getting mapped and you're not getting it passed into startElement you'll need to tell the ParseContext to let it through, by either using the IdentityHtmlMapper or writing your own mapper.
You could run Tika from command line
java -jar tika-app.jar -h [file|port...]
(-h or --html is an option that gives the Output of HTML content)
You could also do it programmatically by using the html parser:
Parser parser = new HtmlParser();
Thats not enough since the HTML parser first transforms the incoming HTML document to wellformed XHTML and then maps the included elements to a “safe” subset. The default
mapping drops things such as and elements that don’t affect the
text content of the HTML page and applies other normalization rules. This default
mapping produces good results in most use cases, but sometimes a client wants more
direct access to the original HTML markup. The IdentityHtmlMapper class can be
used to achieve this:
ParseContext context = new ParseContext();
context.set(HtmlMapper.class, new IdentityHtmlMapper());
Finally you can get your content by calling the parse method:
parser.parse(stream, handler, metadata, context);
Hope this helps a bit. :)
There is a website that displays a lot of data in html tables. They have paged the data so there are around 500 pages.
What is the most convenint (easy) way of getting the data in those tables and download it a CSV, on Windows?
Basically I need to write a script that does something like this but is overkilling to write in in C# and I am looking for other solutions that people with web experience use:
for(i=1 to 500)
load page from http://x/page_i.html;
parse the source and get the data in table with id='data'
save results in csv
Thanks!
I was doing a screen-scraping application once and found BeautifulSoup to be very useful. You could easily plop that into a Python script and parse across all the tags with the specific id you're looking for.
The easiest non-C# way I can think of is to use Wget to download the page, then run HTMLTidy to convert it to XML/XHTML and then transform the resulting XML to CSV with an XSLT (run with MSXSL.exe)
You will have to write some simple batch files and an XSLT with a basic XPath selector.
If you feel it would be easier to just do it in C#, you can use SgmlReader to read the HTML DOM and do an XPath query to extract the data. It should not take more than about 20 lines of code.
I have generated a html table from my web application and save the table into .xls format(in a single word i am generating a .xls sheet from my web application ).
What other setting I have to show it in table form.
You are not producing an XLS file, you are producing a mal-formed HTML file with a name that ends in .xls.
Indeed, you aren't even doing that since there aren't files on the web (there are streams that may or may not end up in files).
Different versions of Open Office, with different settings, will differ in terms of how they deal with stuff that is wrong. The version on one of the machines you are doing is saying "eh, this isn't XLS, oh! it's HTML with a table, I know what to do", while the other is getting as far as "eh, this isn't XLS, it's a bunch of text with strange less-than and greater-than characters all over the place, what do I do".
What you want to do is to produce an actual stream that Open Office and other spreadsheets can deal with. XLS is possible, but pretty hard. Go for CSV instead.
If your table was going to be:
<table>
<tr>
<th>1 heading</th><th>2 & last heading</th>
</tr>
<tr>
<td>1st cell</td><td>This is the "ultimate" cell</td>
</tr>
</table>
Then it sould become:
"1 heading","2 & last heading"
"1st cell","This is the ""ultimate"" cell"
In otherwords newlines to indicate rows, commas to indicate cells, no HTML encoding, quotes around everything and quotes in your actual content doubled-up. (You don't need to always have quotes on your content, but it's never wrong so that's simpler than working out when you do need them).
Now, make your content type "text/csv".
You are now outputting a CSV stream that can be saved as a CSV file. Your spreadsheet software will have a much better idea about what to do with this (it may still ask about character ecodings on opening, but the preview will show you a spreadsheet of data, not a bunch of HTML source all over the place.
It's not really saving as a .xls file -- it appears to be saving as the HTML, but with a .xls extension. How are you generating the .xls? On the server-side, you can provide a button to generate .xls directly (different methods depending on your server platform -- using perl there is the Spreadsheet::WriteExcel module that writes .xls directly, using Java there is JExcel (http://jexcelapi.sourceforge.net/ and POI (http://poi.apache.org/)), other platforms will have their methods.
Okay Subodh, If you want to generate .xls or .csv files, You can't just change the extension of the file and have it open up correctly in that program.
2 Options you have at this point, both involve creating the file with the data on the server and then sending it to the user to download it.
.csv
CSV files are easier to generate from the server side. In a very basic way you can think of them as regular text files with commas(not necessarily only commas) separating individual cells that can be read by spreadsheet programs. For PHP there is an article Here that explains how to generate CSV files.
.xls
xls files are not as simple as simple to generate as CSV files. On the server-side you will need a solution to generate these. For PHP there is a resource Here.
Using xls over CSV has obvious advantage that you can specify formatting and can control visual representation of your data.
Edit :
Upon closely looking at the image you posted, I can see what you are trying to do. If you just want to get that file to open correctly in a spreadsheet program, then don't save it either as CSV or xls
hello.html
<table>
<tr><td>Hi</td><td>Hi</td><td>Hi</td><td>Hi</td></tr>
<tr><td>2</td><td>2</td><td>131</td><td>11312</td></tr>
</table>
Saved as an HTML file will open up correctly(as a proper table) in any spreadsheet program.
To narrow down the problem:
1) Are you opening the same .xls file on both machines?
- what version of OpenOffice is on Machine 1?
- what version of OpenOffice is on Machine 2?
2) How are you creating your .xls file?
- are you just using the response object to change the content-type, or some proprietary software?
- can you include a code sample?
3) Have you tried a pure HTML format?
