    <p>I am looking for algorithm or example code for parsing the test postal address from a text file and convert it to excel report.</p> <p>The text file I receive will have many postal address's in different formats as give below:</p> <pre><code>Unit 8/25 Bright ST, NSW, 2010 UNIT 5, 77 CHAPMAL STREET UNIT 4, 75 GREAT STREET 95 OAKILANDS WAY AVOCADO AVE 628 BRIDGEWATER ABCE ROAD </code></pre> <p>I have to read this file and assign the details to variables for further usage:</p> <p>example -<br> street number from text address should be asigned to 'streetName',<br> unit number should be assigned to 'unitNumber', etc</p> <p>I have pattern matcher which can recognise the values if there are specific details in the string:</p> <pre><code>Pattern p1 = Pattern.compile("([0-9]+\\s+[aA-zZ])+.*"); Matcher m1 = p1.matcher(str); while (m1.find()) { String __tmp = m1.group(); printer = __tmp; } System.out.println("Street : " + printer);; </code></pre> <p>ex: - 4, 75 GREAT STREET : from this text address, the above algorithm is able to identify "75 GREAT" as a street, but the number "4" before the street address should be identified as unit/flat/etc irrespective of weather "4" is joined with "unit"/"flat",etc.</p> <p>I have added one more pattern match to get the numeric before the street address like :</p> <pre><code>Pattern p2 = Pattern.compile("([0-9])"); Matcher m2 = p2.matcher(str); Pattern p3 = Pattern.compile("([,])"); Matcher m3 = p3.matcher(str); while (m2.find() &amp; m3.find()) { String __tmp = m2.group(); printer = __tmp; } System.out.println("Unit : " + printer); </code></pre> <p>This gives me output as:</p> <pre><code>Street : 75 GREAT STREET Unit : 4 </code></pre> <p>but, this algorithm is not working when I append with "unit" or "flat" etc. Can someone help with the solution for this ?</p>

    1. COPost your current solution, perhaps someone can help you get it up to the "best" category.

    2. COYou're not going to be able to use regular expressions to handle this with any sort of accuracy - since the format is completely *irregular*. Have you given some thought to using an API service for this? Something like [Google Maps API](http://stackoverflow.com/questions/7764244/correct-address-format-to-get-the-most-accurate-results-from-google-geocoding-ap)

    3. COya, I have tried Goole Maps API, but this helps only if we are passing enough data to recognise the address. Here in my case, some times I will get only street Name.

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.
