Python：如何在打印到html时保持读取txt文件的中断

Question

当我将内容打印成HTML文件时，我正试图保留从txt文件中读取的换行符。

我以这种方式从samppipe得到结果：

class BottomPipeResult :

    AGENT_ID   = "Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1"

    BOTTOMPIPE_URL = "http://boilerpipe-web.appspot.com/extract?url={0}&extractor=LargestContentExtractor&output=text"

    #BOTTOMPIPE_URL = "http://boilerpipe-web.appspot.com/extract?url={0}&extractor=ArticleExtractor&output=htmlFragment"

    _myBPPage = ""

    # scrape and get results from bottompipe
    def scrapeResult(self, theURL, user_agent=AGENT_ID) :
        request = urllib2.Request(self.BOTTOMPIPE_URL.format(theURL))
        if user_agent:
            request.add_header("User-Agent", user_agent)
            pagefile = urllib2.urlopen(request)
            realurl = pagefile.geturl()
            f = pagefile
            self._myBPPAge = f.read()
        return(self._myBPPAge) 

但是当我将它们重新打印为html时，我放弃了所有的换行符。

这是我用来写入HTML的代码

f = open('./../../entries-new.html', 'a')
f.write(BottomPipeResult.scrapeResult(myLinkResult))
f.close()

这里是一个booilerpipe文本结果的例子：

http://boilerpipe-web.appspot.com/extract?url=http%3A%2F%2Fresult.com&extractor=ArticleExtractor&output=text

我尝试了这个，但它不起作用：

myLinkResult = re.sub('\n','<br />', myLinkResult)

有什么建议吗？

由于

Answer 1

您可以将文字换成＆lt; pre＆gt;标签。这告诉HTML文本是预先格式化的。

例如：

<pre>Your text
With line feeds
and other things
</pre>

Answer 2

我修改了你的代码只是一个触摸，所以它是可以运行的，它似乎对我“正常”工作。结果输出具有预期的行结尾。我看到一些编码问题，但没有行结束问题。

代码

import urllib2

class BottomPipeResult :

    AGENT_ID   = "Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1"
    BOTTOMPIPE_URL = "http://boilerpipe-web.appspot.com/extract?url={0}&extractor=LargestContentExtractor&output=text"
    _myBPPage = ""

    # scrape and get results from bottompipe
    def scrapeResult(self, theURL, user_agent=AGENT_ID) :
        request = urllib2.Request(self.BOTTOMPIPE_URL.format(theURL))
        if user_agent:
            request.add_header("User-Agent", user_agent)
            pagefile = urllib2.urlopen(request)
            realurl = pagefile.geturl()
            f = pagefile
            self._myBPPAge = f.read()
        return(self._myBPPAge) 


bpr = BottomPipeResult()
myLinkResult = 'http://result.com'

f = open('out.html', 'a')
f.write(bpr.scrapeResult(myLinkResult))
f.close()

输出

使结果更像“HTML”，如

就html输出而言，您可能希望将每一行包装在<p>段落标记中。

output = BottomPipeResult.scrapeResult(myLinkResult) 
f.write('\n'.join(['<p>' + x + '</p>' for x in output.split('\n')]))
