How to get tag parameter value with XQuery
For example i have this xml. I need to get value of parameter val
of tag foo
with id="two"
<top>
<sub id="one">
<foo id开发者_开发百科="two" val="bar" />
sometext
</sub>
</top>
Whis this query (using Qt QXmlQuery):
doc('test.xml')/top/sub[@id='one']/foo[@id='two']/<p>{@val}</p>
I receive <p val="bar"/>
, but I need only text "bar" without any tags.
I tried to remove <p>
and </p>
and receive syntax error, unexpected {
How can i get parameter value without any tags?
If you try to serialize just an attribute you will get an error. You may be better off just retrieving the value of the attribute:
doc('test.xml')/top/sub[@id='one']/foo[@id='two']/@val/data(.)
Sorry a bit late in the day... try
data(doc('/db/test/test.xml')/top/sub[@id='one']/foo[@id='two']/@val)
which returns just the text value of the attribute
doc('test.xml')/top/sub[@id='one']/foo[@id='two']/@val
