Hi forum!
I've got the next text:
<book>/data?author=Robert Law&amp;year=2006&amp;code=129&amp;md=H
</book>

I have to separe the string between <book> and </book> after '?' in the following elements:
<book> <author>Robert Law</author>
       <year>2006</year>
       <code>129</code>
       <md>H</md>
</book>

The & character separates each attribute. Is there any way of doing this with XSLT. It's important to say that the number of attributes changes in each book element. Some could include 'md' but other dont, instead could have pt = 3. The idea is to take the name when parsing the string as element name and after '=' correspond to its value.

Thanks in advanced!

Very easy using version 2.0, you can use tokenize function or analyze-string element. With version 1.0 you probably need a recursive template that uses substring-before to read the part upto the ampersand. Create your element and then pass the remaining string to the template etc. until all the string is processed.

In XSLT 2.0 you can use regular expressions to perform such string manipulation, using the xsl:analyze string instruction.

In 1.0 you've only got the functions such as substring-before, contains(), and substring-after(). If the text contains a pattern that repeats a variable number of times, you will need to analyze it using a recursive template. For an example, see the str:tokenize template found at www.exslt.org (you might even be able to use this directly)
