Of course, you had the usual set of new features. But the big new advance was the addition of XML file formats. With Officeyou can save your Microsoft Excel spreadsheet as XML and use the file just as you would the binary equivalent.

The same goes for Microsoft Word. Why are XML file formats so important? Because for years, the true power of Excel or Word was locked in binary file formats that required elaborate converters to access.

In this article, I show how to build a PHP Web application that uses these formats to read data into a database from an Excel spreadsheet and to export the contents of a database table to an Excel spreadsheet.

This application is a table of names and e-mail addresses. To set up the database, create the database using the Mysqladmin command-line tool: You then load the database from the schema file: The user and password authentication you use varies depending on your installation, but the idea remains the same.

First, create the database.

Then use the SQL file to create the tables with the required fields. Create the import data The next step is to create some data for import. Create a new Excel file. In the first workbook, call the top row of columns First, Middle, Last, and Email.

Then, add a few rows of data to the list see Figure 1. Data for import You can make the list as long as you like or change the fields however you see fit.

In a production application, you would probably want to read and parse the header line to determine which fields are in which columns and make the appropriate changes to your import logic. Import the data The import system starts easily enough with a page in which you specify the input Excel XML file see Figure 3.

In the first phase, I simply parse the XML data and output it as a table. In the second phase, I add the logic that inserts the records into the database.

Introduction

Listing 3 shows an example Excel XML file. Note the document header portion at the beginning that describes the document and who is writing it, lays down some visual information, lists styles, an so on. Then, the data comes as a set of worksheets within the main Workbook object.

The first Worksheet object contains the real data. Within that object, the data resides inside the Table tag in a set of Row and Cell tags. Each Cell tag has a Data tag associated with it that holds the data for the cell. In this case, the data is always formatted as String type. By default, when you create a new document, Excel creates three worksheets named Sheet1, Sheet2, and Sheet3.

Listing 4 shows the first version of the import. Then the script finds each Row tag. After the first row, an inside loop parses each Cell tag within the row.

Definition and Usage

The script needs to keep track of that itself.the crxml parser is a real easy to parser. This class has got a search function, which takes a node name with any namespace as an argument. It searches the xml for the node and prints out the access statement to access that node using this class.

Of course, you could write a smarter conversion, which didn't have these limitations, but at that point, you are getting no value out of SimpleXML at all, and should just use the lower level XML Parser functions, or the XMLReader class, to create your structure.

Of course, you could write a smarter conversion, which didn't have these limitations, but at that point, you are getting no value out of SimpleXML at all, and should just use the lower level XML Parser functions, or the XMLReader class, to create your structure.

The SimpleXML Parser. SimpleXML is a tree-based parser. SimpleXML provides an easy way of getting an element's name, attributes and textual content if you know the XML document's structure or layout.

I had a problem with simplexml reading nodes from an xml file. It always return an SimpleXML-Object but not the text inside the node. Example. Reading this page you'd be left with the impression that a class's `serialize` and `unserialize` methods are unrelated to the `serialize` and `unserialize` core functions; that only `__sleep` and `__unsleep` allow you to customize an object's serialization interface.
