This is my HTML:
<h3>test 1</h3>
<p>blah</p>
<h4>subheading 1</h4>
<p>blah</p>
<h4>subheading 2</h4>
<h3>test 2</h3>
<h4>subheading 3</h4>
<p>blah</p>
<h3>test 3</h3>
I am trying to build an array of the h3 tags, with the h4 tags nested within them. An example of the array would look like:
Array
(
[test1] => Array
(
[0] => subheading 1
[1] => subheading 2
)
[test 2] => Array
(
[0] => subheading 3
)
[test 3] => Array
(
)
)
Happy to use preg_match or DOMDocument, any ideas?
The H3 element defines a level-three heading. This heading is more important than an H4 but less important than an H2. The deprecated ALIGN attribute suggests the horizontal alignment for the heading on visual browsers. Possible values are left, right, center, and justify.
Yes . You can use the H1 , H2,.. H6 Tags inside the Table TH tags. These will do the same functionality in the table TH tag too.
With DOMDocument:
"//h3"
to find all <h3>
. These will be the first-level entries in your array$i
(count from 1!) as part of the loop"./following::h4[count(preceding::h3) = $i]"
to find any sub-ordinate <h4>
The XPath expression is "select all <h4>
that have a the same constant number of preceding <h3>
". For the first <h3>
that count is 1, naturally, for the second the count is 2, and so on.
Be sure to execute the XPath expression in the context of the respective <h3>
nodes.
