Assume we have the following html:


    
        TEXT A
        T

    Another way that looks more straightforward to me:

    results = []
root = lxml.hmtl.fromstring(the_html_above)
for tag in root.iter():
    if "TEXT A" in tag.text
        results.append(tag)

    You are very close. Use text()= rather than @text (which indicates an attribute).

    e = root.xpath('.//a[text()="TEXT A"]')

    Or, if you know only that the text contains "TEXT A",

    e = root.xpath('.//a[contains(text(),"TEXT A")]')

    Or, if you know only that text starts with "TEXT A",

    e = root.xpath('.//a[starts-with(text(),"TEXT A")]')

    See the docs for more on the available string functions.

    For example,

    import lxml.html as LH

text = '''\
<html>
    <body>
        <a href="/1234.html">TEXT A</a>
        <a href="/3243.html">TEXT B</a>
        <a href="/7445.html">TEXT C</a>
    <body>
</html>'''

root = LH.fromstring(text)
e = root.xpath('.//a[text()="TEXT A"]')
print(e)

    yields

    [<Element a at 0xb746d2cc>]
