Hi Hélder, > Imagine that I want all elements "campo" with value matching a > determinate patern. For example, I want all elements "campo" whose > value is like "2 digits, a separator("/" or "-"), 2 digits, a > separator("/" or "-"), 4 digits". This is a date! Try something like: /xxx/yyyy/campo[number(substring(., 1, 2)) and (substring(., 2, 1) = '/' or substring(., 2, 1) = '-') and number(substring(., 4, 2)) and (substring(., 2, 1) = '/' or substring(., 2, 1) = '-') and number(substring(., 7, 4))] This will allow things like " 3/ 7/ 4", which you might not want; you could disallow them by adding a "not(contains(., ' '))" clause. Note that XPath 2.0 will allow you to use a regular expression here, so you will be able to do: /xxx/yyyy/campo[matches(., '\d{2}[-/]\d{2}[-/]\d{4}')] Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
