dynamic xpath expression

Question

Good day, colleagues!

Tell me please, how to make a dynamic xpath-parsing:

for example, instead of writing

$domXPath->query('//*[(@id = "article-id-18")]');

-> write something like that

$domXPath->query('//*[(@id = "article-id-*")]');

, because in my case, the site's script generate (every time) a new id for block, that contains article's text?

So question, is above.

Answer 1

Try

$domXPath->query('//*[starts-with(@id, "article-id-")]');
