Ruby - Writing Hpricot data to a file
- by John
Hey everyone,
I am currently doing some XML parsing and I've chosen to use Hpricot because of it's ease of use and syntax, however I am running into some problems. I need to write a piece of XML data that I have found out to another file. However, when I do this the format is not preserved. For example, if the content should look like this:
<dict>
<key>item1</key><value>12345</value>
<key>item2</key><value>67890</value>
<key>item3</key><value>23456</value>
</dict>
And assuming that there are many entries like this in the document. I am iterating through the 'dict' items by using
hpricot_element = Hpricot(xml_document_body)
f = File.new('some_new_file.xml')
(hpricot_element/:dict).each { |dict| f.write( dict.to_original_html ) }
After using the above code, I would expect that the output look like the following exactly like the XML shown above. However to my surprise, the output of the file looks more like this:
<dict>\n", " <key>item1</key><value>12345</value>\n", " <key>item2</key><value>67890</value>\n", " <key>item3</key><value>23456</value\n", " </dict>
I've tried splitting at the "\n" characters and writing to the file one line at a time, but that didn't seem to work either as it did not recognize the "\n" characters. Any help is greatly appreciated. It might be a very simple solution, but I am having troubling finding it. Thanks!
