General Description of the Problem
I have several XMLs coming from different sources and I'm using XSLT to transform them into one standard format that a C# application can parse uniformly. I have already a proof-of-concept transformation already working, and I'm able to transform an XHTML (almost) completely into my standard XML. This question is about that "almost".
The C# application expects that the input xml (the output of the transformation) complies to a format, not only in the structure of the xml elements but also in the format of the data inside the nodes, for example, a <date> element must be in the format of "yyyy/MM/dd", however one input xml (for the transformation) can come in a dd/MM format while another is the way around.
Note that I control the C# application and designed the standard XML template, so changing any of these isn't an issue, I also know the exact format of the different incoming XMLs to be transformed, and I'm developing one transformation for each type of XML I receive, because they can be greatly different from each other and I wouldn't want that by changing the transformation to fit a change in a format I break another that was previously working.
Specific Question about my Problem
So, cutting to the chase, how can I transform the value of the nodes using XLST? How can I tell the transformation to take this node value from (especifically) dd/MM format, and transform it into yyyy/MM/dd?
P.S. I have considered creating an extra XML for configuration so that I can to this type of transformation, for every format, inside C#, however I'd like this to be a last resource. I'd like it so that the output of the XSLT is 100% standard. I have also found some other SO questions describing the process of transforming values, but all of these talk about conditional replacement, seeing if the value equals x and outputting y, that wouldn't do it because dates can be anything.
