使用平面文件进行XSLT转换

Question

Need some inputs on the below problem. I have a flat file which contains Accounts numbers

Account1:Valid 
Account2:Valid 
Account3:Invalid

There is another system generated XML whose contents are transformed in Java via a Transformer class through an XSL file. I need to enhance the XSL file so that it takes Accounts from flat file into consideration and based on Valid or Invalid status, generate the o/p response XML.

Any pointers on how to approach this? In Java application, I have done simple transformation. But how to enhance to take data from Flat File into consideration ?

Answer 1

If you want to do it with the input as shown, then you need to use XSLT 2.0 and later to use unparsed-text("accounts.txt") to read in the text file and for instance parse it with tokenize(unparsed-text("accounts.txt"), '\\n') into lines and/or further with xsl:analyze-string .

XSLT 2.0 is supported in Java by Saxon 9 from http://saxon.sourceforge.net/ .

With XSLT 1.0 all you could do is pass in a string parameter with the file contents and then use the rudimentary string functions in XPath 1.0 and named templates to extract the data.
