java - XPath getting text from an element after a certain element -

-

so right if have this:

//div[@class='artist']/p[x]/text()

x can either 3 or 4, or maybe different number. luckily, if looking not in 3, can check null , go on until find text. issue rather know i'm going right element every time. tried this:

div[@class='people']/h3[text()='h3 text']/p/text()

since there <p> right after <h3>h3 text</h3>. never returns anything, , results in error. if remove /p 'h3 text' returned.

anyway, how <p> directly after <h3>?

btw, i'm using htmlcleaner in java this.

by default when don't specify axis child:: axis, why / operator seems descend dom tree child child. there implied child:: after each slash.

in case don't want find child of <div>, want find sibling of it. sibling element @ same nesting level. specifically, should use following-sibling:: axis.

div[@class='people']/h3[text()='h3 text']/following-sibling::p/text()

xpath axes

axes advanced feature of xpath. 1 of features make xpath powerful.

you're familiar 1 other axis, though may not have realized it: @ symbol shorthand attribute::. when write @href you're saying attribute::href, in attribute called "href" instead of child.

axes, eh? shorthand, eh? tell me more, say? ok!

  • . , .. shorthand more verbose self::node() , parent::node(), respectively. use longer forms if wished.

  • the // operator commonly see //p or body//a has hidden descendant-or-self::node() between slashes. //p shorthand /descendant-or-self::node()/p.
