Hello all,

I have got an XML looks like the following. How can I use an XPATH
command to select //hostname and //instance? If there is no instance in
the sever, just skip, so it returns

<hostname>Host A</hostname>
<instance name="TOM" port="12345"/>
<instance name="TOM1" port="12346"/>
<hostname>Host B</hostname>
<hostname>Host C</hostname>
<instance name="TOM2" port="12345"/>
<instance name="TOM3" port="12346"/>


Basically, I want to select all the hostname, and certain field in the
<serverblock.

Thanks!

=============
<?xml version="1.0" encoding="UTF-8"?>
<servers>
<server>
<record_info>
<lastchecked>20050316</lastchecked>
<hostname>Host A</hostname>
</record_info>
<components>
<instance name="TOM" port="12345"/>
<instance name="TOM1" port="12346"/>
</components>
<supp_info>
<contact name="TOM" email=""/>
<contact name="MARY" email=""/>
</supp_info>
</server>
<server>
......
</server>
<server>
......
</server>
</servers>

//hostname | //instance

The XPath to "all hostname elements, at any dept" is simply //hostname,
which you seem to be aware of... so I presume your question is about how
to request that the XPath be executed, and that depends on what
environment you're working in (which you didn't tell us).

Thanks Richard and Joseph,

//hostname | //instance kind of works, but it will give like all the
hostname, and then all the instance

<hostname>
<hostname>
<hostname>
<instance>
<instance>
<instance>

but i need to have them in order,
like
<hostname>
<instance>
<instance>
<hostname << if there is no instance then just return nothing

<hostname>
<instance>

Sorry I should have mentioned, I am Java and the JDOM API

Any more advice please

Thanks!!

That XPath expression should yield everything in document order. If that
isn't what you're seeing, your implementation of XPath is broken.
