hi group,
I have made a test style sheet to examine how I can use a string value to create nested elements (xslt2, saxon9). The string contains one or more style descriptors; the needed elements have a different name than the corresponding styles. My strategy is to convert the string to a sequence of relevant substrings and then to map the sequence to the right element name. Below I have pasted my stylesheet. For the input document <root/> it creates the expected output <?xml version="1.0" encoding="utf-8"?>
<document>
<BLD>
<ITA/>
</BLD>
</document>My question is: this solution looks clumsy. How can I improve it? My focus is not on the nest-template itself, but on the get_attributes-template and the calling of the nest-template (is the extra blop variable needed?)... thanks in advance, Ruud
