how can i use regex in xpath 1.0

Question

this my xpath

//dns:tbody//dns:td[1][@rowspan="1"]/text()

I want to find a solution how can make the attribute rowspan @rowspan=" only number " accept just number

I'm looking for solution regular expression in XPath 1.0

Regexp =^[0-9]*$ my problem I don't know how to integrate the regex with XPath1.0 or any other solution

With XPath 1.0 you can't, although using regexes would be trivial with XPath 2.0. You could work around it using `number()` — revo, May 15 '18 at 14:47
my xpath will be like that `//dns:tbody//dns:td[1][@rowspan=number()]/text()`?? — MokiNex, May 15 '18 at 14:50

You can use a workaround that tests:

like that:

//dns:tbody//dns:td[1][string(number(@rowspan))!='NaN'][not(starts-with(@rowspan, '-'))][not(contains(@rowspan, '.'))]/text()

or

//dns:tbody//dns:td[1][not(string(number(@rowspan))='NaN' or starts-with(@rowspan, '-') or contains(@rowspan, '.'))]/text()

Try to use below solution instead of regex:

//dns:tbody//dns:td[1][number(@rowspan)<=0 or number(@rowspan)>0]/text()

This should match @rowspan with int value

could you make it for n number? – MokiNex May 15 '18 at 15:12
By *"only number"* you mean any integer? Negative integer, zero? Any? – Andersson May 15 '18 at 15:13

@MokiNex , how about `[number(@rowspan)<=0 or number(@rowspan)>0]`? – Andersson May 15 '18 at 15:27

Some XPath implementations allow you to supply your own functions. You will need to check the documentation on your XPath implementation.

I'm not allowed to use the function just XPath because I'm using a workflow node accept just XPath query – MokiNex May 15 '18 at 15:02
