text - xslt split mp3 tag into artist and title -

Many times, mp3 tags are in the form of "artist - title", but headings are stored in the field.

I want to split prices into Artists + Title fields.

Examples of before / after partitions:

  & lt; Title & gt; Artist - Title & lt; / Title & gt; & Lt; Title & gt; - Title & lt; / Title & gt; & Lt; Title & gt; Artist - & lt; / Title & gt; & Lt; Title & gt; A title & lt; / Title & gt;   
 after:  
    
 I have not done a lot in programming in XSLT, so I do not know if the phrase used in regular languages ​​would fit, and if so, then XSLT language element is the most Good will be used.  
 In this way, I normally take this approach:  
 
 Calculate the first position  
 If it is not found, Return the code> heading  element and an empty  artist  
 if this condition is found at 0, then it will be labeled as  title  element, then  tag as the new  title  element and an empty  artist  element  . 
 If this condition is found on the length-3, then remove it from the  title  element, then the rest of the  title  tag as the new  artist Return  element and an empty  title  
 it is found to be larger than 0, in the form of a  artist  element Everything copies, then return everything to   element    
 
 
 except for talk about 'deletion' and so on, which is not applicable They are (XSLT programs read inputs and produce production; they do not change their input), your description is a very good match. Here (not tested) how to write it (except that I do not give it a very heavy comment):  
   & Lt; / XSL: element & gt; & Lt ;! - * Now emits a title with the rest of the value * - & gt; & Lt; Xsl: element name = "title" & gt; & Lt; XSL: Select & gt; & Lt; Xsl: when test = "is included (., '-')" & gt; & Lt; Xsl: Select the value = "normal-space (overhead-later (., '-'))" /> & Lt; / XSL: When & gt; & Lt; XSL: otherwise & gt; & Lt; XSL: implemented-templates / & gt; & Lt; / XSL: otherwise & gt; & Lt; / XSL: Select & gt; & Lt; / XSL: element & gt; & Lt; / XSL: Templates & gt;
