I am having the following inputs: Your variable's value is not a singleton ... you will get as many start points as you have ranges. You are not working through your value in a piecemeal manner handling one range at a time. When I execute the above code i am getting the following error: Right ... because the sibling axis is grabbing all starts of ranges. I have tried with Now you are just guessing instead of considering the root of your problem of not working with singleton values. The error message was clear, yet you are still trying to work with the improperly-structured first operand. Moreover, the "and" operator is a boolean operator, thus "$start and $end" is a boolean value of true/false and since both operands are non-zero numbers or non-empty strings, the value will always be true. In the code below, I am using <xsl:analyze-string> to give me an opportunity to work with each of the page ranges one at a time. I am making the assumption that the #PCDATA text matches the attribute values, thus I can do the work without looking inside of the attributes. Note that with <xsl:analyze-string> one gets the opportunity to describe a match pattern where each range is dealt with one at a time, thus the "to" operator can work with singleton operands. I hope this helps. . . . . . . . . . . .
