Get an Element Value

Question

Hello,
I was evaluating using XMLType to storing name-values pairs. But there is a problem.
For better understanding: the layout of my XML-Files
<controlResults version="1.0">
<context>
<item>
<name>NN1</name>
<value>VV1</value>
</item>
<item>
<name>NN2</name>
<value>VV2</value>
</item>
<item>
<name>NN3</name>
<value>VV3</value>
</item>
<item>
<name>NN4</name>
<value>VV4</value>
</item>          
<item>
<name>NN5</name>
<value>VV5</value>
</item>
</context>
<status>
<statusCode>0</statusCode>
<statusString/>
</status>
<jobResults>
<data>
<dataEntry>
<name>Any Name</name>
<value>78</value>
</dataEntry>
<dataEntry>
<name>Any Name</name>
<value>90</value>
</dataEntry>
</data>
</jobResults>
</controlResults>
and stored in the Table "XMLTABLE":
CREATE TABLE XMLTABLE ("REQUESTDOKUMENT" "SYS"."XMLTYPE", "ID"
VARCHAR2(200 byte))
Now I need all XML - files where the item/name is NN1
select b.id,
extractValue(value(t),'/item/name') as name
, extractValue(value(t),'/item/value') as value
from xmltable b, table(xmlsequence(extract(requestdokument,'/controlResults/context/item'))) t
where extract(b.requestdokument,'//controlResults/context/item/value/text()') like '%'
and extract(b.requestdokument,'//controlResults/context/item/name/text()') like 'NN1';
This select says: No rows selected.
Can anybody help me, please!
P.S. My Database Release 9.2.0.1.0

Modify the xpath in the SELECT statement.
select b.id,
extractValue(value(t),'name') as name
, extractValue(value(t),'value') as value
from xmltable b, table(xmlsequence(extract(requestdokument,'/controlResults/context/item'))) t
where extract(b.requestdokument,'//controlResults/context/item/value/text()') like '%'
and extract(b.requestdokument,'//controlResults/context/item/name/text()') like 'NN1';
