   • Problems with string.format() with html file in python

     Answered Aug 12, 2012 · 1 votes

     As has already been suggested, a real templating module would give you the best flexibility. However, it is possible to do it how you originally intended. To do so, you can escape the curly braces that should not be used for string formatting. For example, you would want to modify this:

     function MM_swapImgRestore() { //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;}

     as this:

     function MM_swapImgRestore() {{ //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;}}

     When doubled/escaped like this, the format/vformat method will ignore them while parsing. Replacement fields should still have only one set of braces, e.g. {tester}.

     You can use BeautifulSoup:

     from bs4 import BeautifulSoup as soupimport csvwith open('filename.csv', 'w') as f: write = csv.writer(f) header = ['Link']+[i.text for i in soup(data, 'html.parser').find_all('th')] final_results = [[[b.find('a')['href'], b.text] for b in i.find_all('td')] for i in soup(data, 'html.parser').find_all('tr')][1:] write.writerows([header]+[[b[0][0], *[i[-1] for i in b]] for b in final_results])

     Output:

     Link,name,brand,descriptionhttp://abcd.com,abcd,abcd123,abcd 123 (1g)http://efgh.com,efgh,efgh456,efgh 456 (2g)http://ijkl.com,ijkl,ijkl789,ijkl 789 (3g)-

   • python: change data hyperlink in HTML file

     Top Answer

     Answered Feb 22, 2018 · 1 votes

     This is how you could use BeautifulSoup to replace the href attribute.

     from bs4 import BeautifulSoupimport timedata = r'data.html' #html file location#load the filecurrent_time = time.strftime("_%m%d%Y")with open(data) as inf: txt = inf.read()soup = BeautifulSoup(txt, 'html.parser')a = soup.find('a')a['href'] = ("WillCounty_AddressPoint%s.zip" % current_time)print (soup)#save the file againwith open (data, "w") as outf: outf.write(str(soup))

     Outputs:

     <p><a href="WillCounty_AddressPoint_02212018.zip">Address Points</a> (updated weekly)</p>-

     And writes to the file

     UPDATED to use data from supplied file.

     from bs4 import BeautifulSoupimport timedata = r'data.html' #html file location#load the filecurrent_time = time.strftime("_%m%d%Y")with open(data) as inf: txt = inf.read()soup = BeautifulSoup(txt, 'html.parser')# Find the a element you want to change by finding it's text and selecting parent.a = soup.find(text="Address Points").parenta['href'] = ("WillCounty_AddressPoint%s.zip" % current_time)print (soup)#save the file againwith open (data, "w") as outf: outf.write(str(soup))

     It will however, take out blank lines but otherwise leave your HTML code exactly as it was.

     Using a diff tool to see differences in the original and modified files:

     diff data\ \(copy\).html data.html 77c77< <p><a href="Data/WillCounty_AddressPoint.zip">Address Points</a> (updated weekly)</p>---> <p><a href="WillCounty_AddressPoint_02222018.zip">Address Points</a> (updated weekly)</p>116,120d115< < < < < 154d148<

   • Python Flask to change text in a HTML file

     Top Answer

     Answered Oct 31, 2016 · 1 votes

     Flask is a webserver. You are not meant to call the functions with app.route. Replace the last part with:

     if __name__ == '__main__': app.run()-

     and then visit http://127.0.0.1:5000/ in your browser. The template file is not meant to change.

     If for some reason you don't want to run a server but you just want to create HTML files, then use Jinja2, the template engine behind Flask.
