* Fix failure when parsing xlsx with drawing having double (redefined) attributes
* Fix failure when parsing xlsx with drawing having double (redefined) attributes
* Fix#853 when loading and saving XLSX file with empty drawing cause corrupted output file. Store empty drawing as unparsed entity and save it as is when saving the file.
* Fix code style
* Extract character set, so we can convert to UTF-8 if required
* Set column width and row height when defined on tr/td
* Parse align and valign on td
* Specify number format of cell via html attribute
* Formatting of b, strong, i and em tags
* Inserting image in cell when using img tag in html
* Add applying inline styles: border, fonts, alignment, dimensions
* Add tests for applying inline styles
In case we generate Spreadsheet from html file and the code
in file have text color in css "color:#FF00FF" it will showing
as black color because it will render like rgb content with } "FF00FF}"
So, we fix it by adding missing bracket "{".
Closes#831
We now always trust the file extension to avoid false positive of mime
detection for most simple cases. But we still try to guess the mime type
if the file extension does not match or is missing.
Fixes#564
CSV reader used to accept any file without any kind of check. That made
users incorrectly believe that things were ok, even though there is no
way for CSV reader to read anything else that plain text files.
Fixes#167
When describing a cell, the cell reference (r="A1") is optional.
When not present, we should just increment the index of the last processed row.
Fixes#201Closes#225
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
When the xml file is not a standard xml file, the `simplexml_load_string` will return false, this will cause an error on "$xml->getNamespaces(true);" . So instead of showing the error, we throw an exception.
This drop a lot of non-core features code and delegate their maintainance
to third parties. Also it open the door to any missing implementation
out of the box, such as Redis for the moment.
Finally this consistently enforce a constraint where there can be one and
only one active cell at any point in time in code. This used to be true for
non-default implementation of cache, but it was not true for default
implementation where all cells were kept in-memory and thus were never
detached from their worksheet and thus were all kept functionnal at any
point in time.
This inconsistency of behavior between in-memory and off-memory could
lead to bugs when changing cache system if the end-user code was badly
written. Now end-user will never be able to write buggy code in the first
place, avoiding future headache when introducing caching.
Closes#3
Removed "unescape enclosure functionality", since the unescaping is already handled by fgetcsv,
and performing the unescaping again would actually result int the text from the cell being read wrong.
As an example try parsing the folowing CSV:
```
"<img alt="""" src=""http://example.com/image.jpg"" />"
```
With the additional unescaping it would have ended up as:
```
<img alt=" src="http://example.com/image.jpg" />
```
instead of the correct:
```
<img alt="" src="http://example.com/image.jpg" />
```
