python - Finding attribute value using lxml without using a for loop -


this code have @ moment:

>>>p = [] >>>r = root.findall('.//*div/[@class="countdown closed"]/') >>>r '<abbr data-utime="1383624000" class="timestamp"/>' >>>for in r:             s = i.attrib             p.append(s['data-utime']) >>>p ['1383624000']

s yields:

{'class': 'timestamp', 'data-utime': '1383624000'}

i think code above verbose(creating list, using loop 1 string).

i know lxml capable of achieving more succinctly unable achieve this, appreciate assistance.

use xpath, not elementtree findall() (which more limited , restricted language present compatibility elementtree library lxml extends), , address path way down attribute:

root.xpath('//html:div[@class="countdown closed"]/@data-utime',   namespaces={'html': 'http://www.w3.org/1999/xhtml'})

(it is possible use namespace wildcards in xpath, not great practice -- not leave 1 open namespace collisions, can performance impediment if engine indexes against fully-qualified attribute names).

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
