Use

 string-join(p/img/@alt, "")

that will first select the text of all alt attributes and then combine it in a string

any other function instead of string-join. The Parser doesn't support this function. Can we Use concat any how ???

BeniBela Over a year ago

With concat you could do it like concat(p/img[1]/@alt,p/img[2]/@alt,p/img[3]/@alt,p/img[4]/@alt,p/img[5]/@alt,p/img[6]/@alt,p/img[7]/@alt). (if there are more img in the concat call than in the html they are ignored). But it is better to switch to another parser that supports the most basic function.

If it supports xpath 2, you could also move the p/ out to make it a little bit simpler p/concat(img[1]/@alt,img[2]/@alt,img[3]/@alt,img[4]/@alt,img[5]/@alt,‌img[6]/@alt,img[7]/@alt)

In Xpath 2, you have string-join

string-join(p[@class='pd-price']/img/@alt, '')
