Parsing XML as a Query Object in ColdFusion
Overview
In the financial sector, developers often work with XML for back-office processing, such as loan applications and internet banking. These systems often interact with databases like DB2, returning data in XML format. ColdFusion offers efficient methods to handle XML, especially by converting it into Query objects familiar to developers.
The Process
Let's explore how to parse XML into a Query object in ColdFusion using a phonebook example.
Sample XML
Here's a sample phonebook XML structure:
```xml
```
Reading the XML
First, load the XML into a variable using ColdFusion:
```html
```
Accessing XML Elements
Extract child nodes and determine size:
```html
```
Creating a Query Object
Define the Query object, simulating a database table:
```html
```
Populating the Query
Fill the Query object with XML data:
```html
```
Using ColdFusion Components
Leveraging ColdFusion Components (CFCs) enhances reusability:
```html
```
Here’s the CFC function for sorting by last name:
```html
SELECT * FROM arguments.q_obj ORDER BY lastName, cat
cfcatch.message#
```
Displaying Results
Output the query result in an HTML table:
```html
| Category | First Name | Last Name | Phone | |
|---|---|---|---|---|
cat# | #firstName# | #lastName# | #phone# | #email# |
```
Conclusion
Using XML with ColdFusion and converting it to Query objects allows you to leverage SQL skills with XML. It's a powerful approach that aligns well with ColdFusion's capabilities. Happy coding!
