PHPExcel无法读取XML单元格中的完整数字

Question

I must extract data from a third party XML file. All is fine expect for one column that contains numbers with comma thousand separator,and dot decimal separator.

A number normally represented as "10,000.00" in Excel or OpenOffice, is read by PHPExcel as "10" only.

require_once dirname(__FILE__) . '/../Classes/PHPExcel/IOFactory.php';

$inputFileName = "myfile.xml";

/**  Identify the type of $inputFileName  **/
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);

/**  Create a new Reader of the type that has been identified  **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);

/**  Load $inputFileName to a PHPExcel Object  **/
$objPHPExcel = $objReader->load($inputFileName);

$format = $objPHPExcel->getActiveSheet()->getStyle('C24')->getNumberFormat()->getFormatCode();

Note that format code of the cell is returned as General

Trying to read one of the cell causing problems using:

$getValue = $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(2, 24)->getValue();
$getCalculatedValue = $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(2, 24)->getCalculatedValue();
$getFormattedValue = $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(2, 24)->getFormattedValue();

Always the same value, truncated at the thousand separator: "10" instead of "10,000.00"

Here's the details of the xml file:

`<?xml version="1.0" encoding="UTF-8"?>
<?mso-application progid="Excel.Sheet"?>
<ss:Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:ext="http://fxcm.com/xslt/extension" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:of="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:html="http://www.w3.org/TR/REC-html40">`

STYLE DEFINITION

`<ss:Style ss:ID="cell_merged_top_odd_integer" ss:Parent="cell_merged_top_odd">
            <ss:NumberFormat ss:Format="#,##0"/>
</ss:Style>`

CELL WITH NUMBER CAUSING PROBLEM

`<ss:Cell ss:StyleID="cell_merged_top_odd_integer" ss:Index="3">
    <ss:Data ss:Type="Number">10,000.00</ss:Data>
</ss:Cell>`

MANUAL WAY TO FIX THE PROBLEM When I save the file from OpenOffice or Excel, the following message pops up warning message OpenOffice , and PHPExcel finally works as expected, reading "10000".

I cannot act on the third party to change its XML file, nor can I ask the user to re-save the file prior to uploading it on my website.

Any idea of what could possibly go wrong here perhaps?

Answer 1

As suggested by Mark Baker, I took the problem at the source, went through the process of PHPExcel in order to str_replace the comma.

In the file Excel2003XML.php (the first library called after identifying the file type), I have modified the public function loadIntoExisting() as follows:

public function loadIntoExisting($pFilename, PHPExcel $objPHPExcel)
    {
    ...
    if (isset($cell->Data)) {
       $cellValue = $cellData = $cell->Data;
       //REPLACE THE COMMA
       $cellValue = str_replace(",", "", $cellValue);
    ...
    }
}

I am conscious that this will affect all cells containing a comma but so far it fixes the problem. I'll be looking in replacing the comma only when a specific number format is detected later on.

Meanwhile, thank you Mark for your guidance!

Not surprising that PHPExcel reads only 10 when reading a number that actually contains a string value of 10,000.00 The ss:Data for a ss:Type of Number should contain a numeric value, not a formatted string; ie. it should contain an actual numeric value of 10000 , and the ss:Index should point to the formatting... Because the XML has said that the value is numeric, then PHPExcel is trying to read it as a numeric, using standard loose-typing rules; and as , is not a numeric value, it's only reading the digits up to that non-numeric character
