I want to know if # -- using utf8 -- is the same in PA? iwant to put after #!/usr/bin/python

I am facing some error ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters which I want to fix

I try to declare with # coding: utf-8 also not working. I am suing Flask

The comment to set the coding should be

# -*- coding: utf-8 -*-

...on a new line after the initial hashbang line -- note the dashes and stars. Could you try that and see what happens?

@app.route('/thtop', methods=['GET'])
@app.cache.cached(timeout=60)
def thtop():
    page_th = requests.get('http://www.settrade.com/C13_MarketSummary.jsp?order=Y')
    th = html.fromstring(page_th.content)
    a= th.xpath('//div[@class="divDetailBox" and .//h3[.="มูลค่าซื้อขาย 20 อันดับ"]]//tr/td/text()')
    return "okay"

I don't know when I move to PA, it just repeated the ASCII error.

In line 11 the argument to xpath needs to be a Unicode literal, so prefix with u.

a = xpath(u'//div[...

What is the full error stacktrace btw? If it's line 11, aren't you just trying to give it unicode characters while xpath is saying it doesn't accept unicode characters? "ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters"

Hi conrad,

u' eliminate the error.

However, I still find that the Thai do not take effect. No matter I change the Thai words the output of xpath still the same

What's the return value that you get from the th.xpath function?
