I’m been working on a project where I need to extract attachments from an InfoPath form. There are some good resources for parsing InfoPath forms (na lamang ang XML file, kaya talagang medyo madali).

Habang ako ay pagbuo up ang proyekto, I started by downloading an InfoPath form and saving it to my local hard drive. My c# code was reading directly from that instance. Gayunman, the InfoPath forms are really living inside a SharePoint forms library. I did a little half hearted searching to find out how to read it directly from the library and almost gave up, in which case I would have saved the form to a local temp directory and read it from there. Gayunman, there’s no need to go through those hoops as you can read it directly from the library. This little snippet shows how:

/// Class kahulugan bagay-bagay dito, kasama:

pribado SPFile mySharePointFile; /* Bahagi ng isang SPList */

// Higit pang code dito napupunta at sa loob ng isang pamamaraan ng klase mayroon kami:
XmlTextReader textReader;

textReader = bago XmlTextReader(mySharePointFile.OpenBinaryStream());

textReader.WhitespaceHandling = WhitespaceHandling.Wala;

textReader.Read();

// Kung ang node ay may halaga

habang (textReader.Read())
{

Sila key bit sa itaas ay na maaari naming basahin ang InfoPath nang direkta sa pamamagitan ng OpenBinaryStream() method call on the SPFile as a parameter to the constructor on XmlTextReader. It works great.
