    text
    copied!<p>This is one of my first forays into Python. I'd normally stick with bash, however Minidom seems to perfectly suite my needs for XML parsing, so I'm giving it a shot.</p> <p>First question which I can't seem to figure out is, what's the equivalent for 'grep -v' when parsing a file?</p> <p>Each object I'm pulling begins with a specific tag. If, within said tag, I want to exclude a row of data based off of a certain string embedded within the tag, how do I accomplish this?</p> <p>Pseudo code that I've got now (no exclusion):</p> <pre><code>mainTag = xml.getElementsByTagName("network_object") name = network_object.getElementsByTagName("Name")[0].firstChild.data </code></pre> <p>I'd like to see the data output all "name" fields, with the exception of strings that contain "cluster". Since I'll be doing multiple searches on network_objects, I believe I need to do it at that level, but don't know how.</p> <p>Help! :)</p> <p>@Martijn, thank you for the help, however Etree is giving me a ton of problems...can you show me how to do this with minidom?</p> <p>This obviously doesn't work: Damnit, I'm having a ton of trouble with ETree..Gone back to minidom since I can copy/paste and be finished in a few minutes.</p> <p>Can you give me some logic to do this with minidom?</p> <p>This obviously doesn't work:</p> <pre><code>name = network_object.getElementsByTagName("Name")[0].firstChild.data if name is not 'cluster' in name continue </code></pre>
