Re: [dom4j-user] XPath result from a DOM and the Rest of DOM

Mon, 18 Nov 2002 21:58:04 -0800


James,
 
I have realized that the right approach will be the one Dave and you suggested. The
last question(i think) for this thread will be how can I add a new element at the same
location where we removed the old element.
 
In Xerces, it's easy to do it with one method. But I am new to DOM4J. How can we do
it with DOM4J. Thank you.
 
Regards,

Just remove the ContactInfo element from the document and what you have left will be what you need..
 
Document patient = ...;
Node contactInfo = patient.selectSingleNode("/Patient/ContactInfo");
 
// remove it
contactInfo.detach();
 
// now the patient document looks like the expected result

Thank you for your reply as well as code snippet. But that's not exactlly
what I was looking for.
 
My applogies if I did not explained well in my prevous message. The
code snippet in your message will be able to get the <ContactInfo>
subemelement fine. And I have no problem to getting that.
 
My question was to get the rest of XML DOM, excluding the prviously
selected sublelement, <ContactInfo>. To wit, I am looking for a simple
way to get the result without parsing the XML document by excluding
the previously selected subelement. The result I am expecting to get
is as follows:
 
Initial XML:
<Patient>
    <Age>39</Age>
    <Gender>Female</Gender>
    <ContactInfo>
        <PhoneNumber>123-456-7890</PhoneNumber>
        <EmailAddress>[EMAIL PROTECTED]</EmailAddress>
    </ContactInfo>
</Patient>
The result XML:
<Patient>
    <Age>39</Age>
    <Gender>Female</Gender>
</Patient>
Thank you.
 
Any more comments?
 
Regards,
 
 
Pae

If I understand you correctly, the following will return <Patient> element:


SAXReader reader = new SAXReader();
Document document = reader.read( new File( "patient_records.xml" ) );
Element contactInfo = document.selectSingleNode( "//ContactInfo", "." );
Element patient = contactInfor.getParent();


Then you can use the Node API to traverse the <Patient> element returned.

Also, if <Patient> is the root element, then you can do the following:

SAXReader reader = new SAXReader();
Document document = reader.read( new File( "patient_records.xml" ) );
Element patient = document.getRootElement();



Best regards

Ben

    </ContactInfo>
</Patient>

And we use the XPath to only get the <ContactInfo>, e.g.,
"//ContactInfo" which should get the result as follows;

    <ContactInfo>
        <PhoneNumber>123-456-7890</PhoneNumber>
        <EmailAddress>[EMAIL PROTECTED]</EmailAddress>
    </ContactInfo>

My question is:

[Q] Is there way to get the rest of XML document in a simple
      way. The rest of XML document should be as follows;

<Patient>
    <Age>39</Age>
    <Gender>Female</Gender>
</Patient>

Any comments? Thank you.

Regards,


Pae
