lxml

I am generating an SVG file that's intended to include Inkscape-specific tags. For example, inkscape:label and inkscape:groupmode . I am using lxml etree as my parser/generator. I'd like to add the label and groupmode tags to the following instance: layer = etree.SubElement(svg_instance, 'g', id="layer-id") My question is how do I achieve that in order to get the correct output form in the SVG, for example: <g inkscape:groupmode="layer" id="layer-id" inkscape:label="layer-label"> First, remember that inkscape: isnt' a namespace, it's just a convenient way of referring to a namespace that is

I have some lxml element: >> lxml_element.text 'hello BREAK world' I need to replace the word BREAK with an HTML break tag— <br /> . I've tried to do simple text replacing: lxml_element.text.replace('BREAK', '<br />') but it inserts the tag with escaped symbols, like <br/> . How do I solve this problem? Here's how you could do it. Setting up a sample lxml from your question: >>> import lxml >>> some_data = "<b>hello BREAK world</b>" >>> root = lxml.etree.fromstring(some_data) >>> root <Element b at 0x3f35a50> >>> root.text 'hello BREAK world' Next, create a subelement tag <br>: >>> childbr =

I've got this xpath query: /html/body//tbody/tr[*]/td[*]/a[@title]/@href It extracts all the links with the title attribute - and gives the href in FireFox's Xpath checker add-on . However, I cannot seem to use it with lxml . from lxml import etree parsedPage = etree.HTML(page) # Create parse tree from valid page. # Xpath query hyperlinks = parsedPage.xpath("/html/body//tbody/tr[*]/td[*]/a[@title]/@href") for x in hyperlinks: print x # Print links in <a> tags, containing the title attribute This produces no result from lxml (empty list). How would one grab the href text (link) of a hyperlink

I used BeautifulSoup to handle XML files that I have collected through a REST API. The responses contain HTML code, but BeautifulSoup escapes all the HTML tags so it can be displayed nicely. Unfortunately I need the HTML code. How would I go on about transforming the escaped HTML into proper markup? Help would be very much appreciated! I think you want xml.sax.saxutils.unescape from the Python standard library. E.g.: >>> from xml.sax import saxutils as su >>> s = '<foo>bar</foo>' >>> su.unescape(s) '<foo>bar</foo>' You could try the urllib module? It has a method unquote() that might suit your
