    <p>I am getting trouble with the following matter.Let's say, I have some string in two list in a dictionary:</p> <pre><code> left right british 7 cuneate nucleus Medulla oblongata Motoneurons anterior </code></pre> <p>And I have some test lines in a file as like below:</p> <pre><code>&lt;s id="69-7"&gt;British Meanwhile is the studio 7 album by british pop band 10cc 7.&lt;/s&gt; &lt;s id="5239778-2"&gt;Medulla oblongata,the name refers collectively to the cuneate nucleus and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.&lt;/s&gt; &lt;s id="21120-99"&gt;Terior horn cells, motoneurons located in the spinal.&lt;/s&gt; </code></pre> <p>I want to get output as like following way:</p> <pre><code>&lt;s id="69-7"&gt;&lt;w2&gt;British&lt;/w2&gt; Meanwhile is the studio &lt;w2&gt;7&lt;/w2&gt; album by &lt;w1&gt;british&lt;/w1&gt; pop band 10cc &lt;w2&gt;7&lt;/w2&gt;.&lt;/s&gt; &lt;s id="5239778-2"&gt;&lt;w2&gt;Medulla oblongata&lt;/w2&gt;,the name refers collectively to the &lt;w1&gt;cuneate nucleus&lt;/w1&gt; and gracile nucleus, which are present at the junction between the spinal cord and the &lt;w2&gt;medulla oblongata&lt;/w2&gt;.&lt;/s&gt; </code></pre> <p>I tried with the following code:</p> <pre><code>import re def textReturn(left, right): text = "" filetext = open(text.xml, "r").read() linelist = re.split(u'[\n|\r\n]+',filetext) for i in linelist: left = left.strip() right = right.strip() if left in i and right in i: i1 = re.sub('(?i)(\s+)(%s)(\s+)'%left, '\\1&lt;w1&gt;\\2&lt;/w1&gt;\\3', i) i2 = re.sub('(?i)(\s+)(%s)(\s+)'%right, '\\1&lt;w2&gt;\\2&lt;/w2&gt;\\3', i1) text = text + i2 + "\n" return text </code></pre> <p>But it gives me:</p> <pre><code>'&lt;s id="69-7"&gt;British meanwhile is the studio &lt;w2&gt;7&lt;/w2&gt; album by &lt;w1&gt;British&lt;/w1&gt; pop band 10cc 7.&lt;/s&gt;'. &lt;s id="5239778-2"&gt;Medulla oblongata,the name refers collectively to the &lt;w1&gt;cuneate nucleus&lt;/w1&gt; and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.&lt;/s&gt; &lt;s id="21120-99"&gt;Terior horn cells, &lt;w1&gt;motoneurons&lt;/w2&gt; located in the spinal.&lt;/s&gt; </code></pre> <p><strong>i.e It can't tag if there are string at the beginning &amp; end .</strong></p> <p><strong>Also,I just want to get return those line ,which matches both left &amp; right strings, NOT others line.</strong></p> <p>Any solution please! Thanks a lot!!! </p>

    1. COThat input looks like XML. Are you sure you don't need to pull the strings out with an XML parser? Also, REs really should use raw strings (r'...') since they don't treat backslashes specially..

    2. COKeith has a good point. It is probably not a good idea to rely on the entire `s` element to be on a single line. You can only get away with finding elements yourself if you take into account literal strings, CDATA sections, processing directives, etc. but why would you want to when xml parsers do that for you already? There is a learning curve to using them, as well as XSLT (for modifying the docs the way you want to) but it is sooooooo worth it!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
