Hello!

I have an XML-File with the following structure. The XML-Data is stored into an XMLTYPE-Tablecolumn.

<DATA>
<Common>
<Field>
<Label>Begin Date </Label>
<Value Name="BEG_DATE">02.05.2006</Value>
</Field>
<Field>
<Label>End Date</Label>
<Value Name="END_DATE">01.06.2016</Value>
</Field>
<Field>
<Label>type</Label>
<Value Name="TYPE">Example</Value>
</Field>
</Common>

<Customer>
<Field>
<Label>Name</Label>
<Value Name="CUST_NAME">Smith</Value>
</Field>
<Field>
<Label>Date of birth</Label>
<Value Name="CUST_BIRTH_DATE">27.08.1972</Value>
</Field>
</Customer>
</DATA>

What I want to do is to update a specific value. For example "END_DATE" to "02.06.2017".

I tried the following SQL but it always updates all Value-Nodes:

UPDATE XML_TAB xt
SET xt.xml = updateXML(xt.XML,'/DATA/Common/Field/Value/text()','02.06.2017')
WHERE xt.ID = :update_id
AND existsNode(xt.XML,'/DATA/Common/Field/Value[@Name="END_DATE"]') = 1

Thanks for your help!

Try something like this:

UPDATE xml_tab
SET xml = updateXML(xml, '/DATA/Common/Field/Value[@Name="END_DATE"]/text()', '02.06.2017')
WHERE id = :update_id;

Best regards.

I think you can only update parts of XML if you have create the XMLType column with a DTD attached to it. If you simply created the table as : create table test (y xmltype) it is internallystored as text (check ORACL XML manuals).
