I am new to programming so bear with me. I have an XML document that looks like this:
File name: PRIDE1542.xml
<ExperimentCollection version="2.1">
<Experiment>
<ExperimentAccession>1015</ExperimentAccession>
<Title>**Protein complexes in Saccharomyces cerevisiae (GPM06600002310)**</Title>
<ShortLabel>GPM06600002310</ShortLabel>
<Protocol>
<ProtocolName>**None**</ProtocolName>
</Protocol>
<mzData version="1.05" accessionNumber="1015">
<cvLookup cvLabel="RESID" fullName="RESID Database of Protein Modifications" version="0.0" address="http://www.ebi.ac.uk/RESID/" />
<cvLookup cvLabel="UNIMOD" fullName="UNIMOD Protein Modifications for Mass Spectrometry" version="0.0" address="http://www.unimod.org/" />

<sampleName>**GPM06600002310**</sampleName>
<sampleDescription comment="Ho, Y., et al., Systematic identification of protein complexes in Saccharomyces cerevisiae by mass spectrometry. Nature. 2002 Jan 10;415(6868):180-3.">
<cvParam cvLabel="NEWT" accession="4932" name="Saccharomyces cerevisiae (Baker's yeast)" value="Saccharomyces cerevisiae" />
</sampleDescription>
</admin>
</description>
<spectrumList count="0" />
</mzData>
</Experiment>
</ExperimentCollection>
I want to take out the text in between <Title>
, <ProtocolName>
, and <SampleName>
and put into a text file (I tried bolding them to making it easier to see). I have the following code so far (based on posts I saw on this site), but it seems not to work:
>> require 'rubygems'
>> require 'nokogiri'
>> doc = Nokogiri::XML(File.open("PRIDE_Exp_Complete_Ac_10094.xml"))
>> @ExperimentCollection = doc.css("ExperimentCollection Title").map {|node| node.children.text }
Can someone help me?
