如果H2包含某些文本，如何选择H3的内容

Question

I would like to scrape the content of the H3 element if the H2 just above it contains a certain text, in this case the H2 should contain "Course advanced Sydney".

But I can't get the Xpath to work. Someone who can solve this issue? Unfortunately I'm not very experienced with Xpath. But I understand the basics.

I tried this with Xpath:

//div[@id='training']/article/[h2/text() = 'Course advanced Sydney']/h3

The code:

    <div id="training" class="overview">
        <article>
            <h2>Course beginner Amsterdam</h2>
            <h3>20 May 2019</h3>
        </article>
        <article>
            <h2>Course advanced Sydney</h2>
            <h3>27 May 2019</h3>
        </article>
        <article>
            <h2>Course beginner Sydney</h2>
            <h3>6 June 2019</h3>
        </article>
        <article>
            <h2>Course medior New York</h2>
            <h3>16 June 2019</h3>
        </article>
    </div>

I expect the output to be "27 May 2019", but the actual output is "#N/A"

Answer 1

The h3 element is not a descendant of the h2 , it is its sibling. So use

//div[@id='training']/article/h2[contains(., 'Course advanced Sydney']/following-sibling::h3
