XPath by style?

[Phil]

<div width="123"></div>
<div style="foo: doo; width: 123px; bar: gar;"></div>
<div width="124"></div>
<div style="foo: doo; width: 124px; bar: gar;"></div>

I know how to construct an XPath expression that'll select the first
<div>, but is there one that'll select the first two but not the others?

<div width="123"></div>
<div style="foo: doo; width: 123px; bar: gar;"></div>
<div width="124"></div>
<div style="foo: doo; width: 124px; bar: gar;"></div>

Yes. I mailed you an example.

Use a predicate to select the first and second element by position e.g.
div[position() < 3]

div[position() < 3]

Sorry if I wasn't clear - the elements aren't necessarily in that order.
What I need to do is select all elements with a width of 123px,
regardless of whether the width is specified as a style or an attribute.

Ah, I see. Check your inbox.

XPath is off-topic here (as it is *not* a JS-dependent technology), and your
From header constitutes a violation of Internet standards and disregard of
Netiquette. RTFM.

XPath (at least version 1.0) has only basic string manipulation
functions so parsing the CSS properties in the inline style attribute is
rather difficult. I think in that case it is better not to use XPath to
try to check the CSS width but rather use element.style.width (or even
window.getComputedStyle depending on what kind of CSS value you are
looking for).
