C Convert Xml To Pdf
Posted : admin On 03.12.2019Note: The following post was originally published over on Dzone. Creative labs sb0670 drivers. I changed the title because I already wrote several XML parsing articles and don’t want my readers to get this one confused with the others.
The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. Technical details. I pay a one time and can use «PDF Focus.Net» for a whole life without any additional fees. My license will never expires. As bonus, I get unlimited technical support during a whole life for free and independently of the date of my purchasing. Some examples to convert PDF to XML in C# and VB.Net. Convert PDF file to XML file in C#.
One of the common tasks I am given in my day job is to take some data format input and parse it to create a report or some other document. Today we’ll look at taking some XML input, parsing it with the Python programming language and then creating a letter in PDF format using Reportlab, a 3rd party package for Python. Let’s say my company receives an order for three items that I need to fulfill. The XML for that could look like the following code:
Battlezone 2 game. A race called the Scions declares war on humanity. Activision gave the nod to developer Pandemic Studios to go ahead with a sequel, even though the original failed to ignite at retail. The final product is an above average shooter, but one that reeks of early release.Battlezone 2 pretty much abandons the silly-yet-cool “Cold War in Space” plot of the original and drops in its place the most cliched and hackneyed alien-invasion story imaginable.

Save the code above as order.xml. Now I just need to write a parser and PDF generator script in Python. You can use Python builtin XML parsing libraries which include SAX, minidom or ElementTree or you can go out and download one of the many external packages for XML parsing. My favorite is lxml which includes a version of ElementTree as well as a really nice piece of code that they call “objectify”. This latter piece will basically take XML and turn it into a dot notation Python object. I’ll be using it to do our parsing because it is so straight-forward, easy to implement and understand. As stated earlier, I’ll be using Reportlab to do the PDF creation piece.
Here’s a simple script that will do everything we need:
Here’s the PDF output: letter.pdf
Let’s take a couple minutes to go over this code. First off is a bunch fo imports. This just sets up our environment with the needed compents from Reportlab and lxml. I also import the decimal module as I will be adding amounts and it is much more accurate for float mathematics than just using normal Python math. Next we create our PDFOrder class which accepts two arguments: an xml file and a pdf file path. In our initialization method, we create a couple class properties, read the XML file and return an XML object. The coord method is for positioning Reportlab flowables, which are dynamic objects with the ability to split across pages and accept various styles.
The createPDF method is the meat of the program. The canvas object is used to create our PDF and “draw” on it. I set it up to be letter sized and I also grab a default stylesheet. Next I create a shipping address and position it near the top of the page, 18mm from the left and 40mm from the top. After that, I create and place the Order Number. Finally, I iterate over the items in the order and place them in a nested list, which is then placed in Reportlab’s Table flowable. Finally, I position the table and pass it some styles to give it a border and an inner grid. Lastly, we save the file to disk.
The document is created and I’ve now got a nice prototype to show my colleagues. At this point, all I need to do is tweak the look and feel of the document by passing in different styles for the text (i.e. bold, italic, font size) or changing the layout a bit. This is usually up to management or the client, so you’ll have to wait and see what they want.

Now you know how to parse an XML document in Python and create a PDF from the parsed data.
