I’m trying to export a large amount of data from my MySQL database to an XML file using CGI through an HTTP service. After creating the XML file, I want to read it and display its contents in a list. Could someone share an example of how to do this? I appreciate any help and sample code you can provide.
hey try streaming results in chunks. i used php’s xmlwriter to flush partial xml as data comes from mysql, then parsed it with a light parser for listing. it saves mem and is easy to debug.
I encountered a similar requirement in one of my projects where I needed to export a large dataset from MySQL to an XML file and then display it using a list. I solved it by creating a CGI script in Python that connected to the database, executed a query, and iteratively built an XML structure using libraries such as xml.etree.ElementTree. After writing the XML to a file, I implemented a separate module to parse this file and generate the list for the front end. This modular approach helped in isolating data export from presentation, making it easier to troubleshoot and maintain over time. Testing edge cases and ensuring proper error handling was also critical in my solution.
hey, i tried using a sax parser before. it reads xml as the file streams in so no memory overload. maybe try reading asynchronously too? whatcha think about async approaches when handling huge datasets?
In a recent project, I addressed a similar challenge by restructuring the data export process. I used a buffered approach to create the XML file, ensuring data was written in small, manageable sections to minimize memory overhead. This method allowed for a more stable export of large datasets. Subsequently, I employed an iterative parser to read and convert the XML into a list format for display. Emphasizing error handling and ensuring that each data segment was processed correctly contributed significantly to the efficiency and reliability of the solution.
