Java Forum / General / October 2006Get Data and Value of XML element in Java
I am new to Java. I need to rewrite a function which gets XML elements text as shown below to get elements value instead: private String getCharacterDataFromElement(Element e){ Node child = e.getFirstChild(); if(child instanceof CharacterData){ CharacterData cd = (Character) child; return cd.getData(); } return "?"; } <xml>FUNCTION ABOVE GETS THIS<xml> <xml value="NEED TO GET THIS VALUE"></xml> THANKS TO ALL. >I am new to Java. I need to rewrite a function which gets XML elements > text as shown below to get elements value instead: [quoted text clipped - 13 lines] > > THANKS TO ALL. http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/text/Element.html#getAttributes() - Oliver Thank you Oliver, but I saw it many times. The problem is: I am new to Java... I cannot understand how to use it. Andrew, I will send you the code to your personal email... What is it? Thanks. > Thank you Oliver, but I saw it many times.

If you have a specific question about Java, we can try to answer it. Otherwise, I can only recommend that you google for "Java tutorial" and follow the tutorials you find. - Oliver Oliver, Your recommendations are stronly considered. By the way, I was always wondering, what is the reason of being helped on Google Groups? Is it because some people want to really help others, or there may be something behind this? I really wonder. Or maybe I have to do something in return. Please, help me know. Thank you. > Oliver, > Your recommendations are stronly considered.

You'd probably have to ask a psychology newsgroup for that one. - Oliver > Oliver, > Your recommendations are stronly considered.

"Google Groups" is just a web-site that let you view and post to UseNet newsgroups. Most experienced people won't even browse into "GG", but use a dedicated News Client, which is *made* for participating on Usenet. Second, it is because some people want to really help others. And because those who help others also learn from the discussions themselves.  SignatureDag. > I am new to Java. Wow! >...I need to rewrite a function which gets XML elements > text as shown below to get elements value instead: Cool! When you finish, could you send me the codes too?

You should become familiar with the API Javadocs, as you'll find a great part of what you want to know in there. For this question, start with <http://java.sun.com/j2se/1.5.0/docs/api/org/w3c/dom/Node.html>. Assuming that the parameter "e" is the element in your (incorrect) examples named "xml", you can get the value of the attribute named "value" using: String value = e.getAttribute("value"); If the attribute doesn't exist or is an empty string, you'll get an empty string in return. To get the value of the text node, you could try this: if (e.getFirstChild().getNodeType() == Node.TEXT_NODE) { String nodevalue = e.getFirstChild().getNodeValue(); } = Steve = SignatureSteve W.
