how can i search xml file by user input string using DOM in Python ?

[golnaz hgh]

the xml file is like this:

<publist> 
 <book>  
   A book entry has the following fields:
          o Title;
          o One or more authors;
          o Publisher;
          o Year
 </book> 
<article>
   An article entry has the following fields:
          o Title;
          o One or more authors;
          o Journal title;
          o Issue number;
          o Range of pages;
          o Year
</article>
</publist>
 

------------------------------------------
I should provide something like this:
Search by title (t) or by author (a)?
Enter your choice: a
Write a string that the surname should contain: Moeller
Found 2:

... prints the XML contents of the book entry by Anders Moeller ...

1: Delete
2: Next item
0: Main menu
Enter your choice: 1

... prints the XML contents of the book by Sara B. Moeller ...

1: Delete
2: Next item
0: Main menu
Enter your choice: 2

I like minidom. Read in the XML file as a string and pass the string to xml.dom.minidom.parseString() to create a xml.dom.minidom.Document instance. Instance method getElementsByTagName() will return a list of elements with matching tags.

You may want to freshen up on XML basics. I like this tutorial for beginning XML.

We cannot write the code for you, so post your code and we will be glad to help.
