i want to create some data structure that will amount of 20K xml.
xml structure will be of type :
<XML><GUID>fcf2664e-d641-48a7-a1aa-2e8fef5145e6</GUID><DATA>.....</DATA><XML>
<XML><GUID>62040b2d-52a4-4ce0-814f-ff5530dde6fc</GUID><DATA>.....</DATA><XML>
and so on...
i want to achive 2 things:
1) i want to remove xml after XX minutes (xx will be general number for all the XML)
2) i want to search over the structure and find the xml by its GUID.
whats the best way to implement this?
First of all, the xml you posted isn't valid xml because it's missing closing xml tags (e.g. </XML>).
That being said, do you have control over the xml schema? If so, I would suggest you change the schema to have the guid/data pair as a single node of the xml (rather than a data node following a guid node).
Something like (...please ignore the names I've chosen):
Once you have the xml in a format like this (if it's possible), then you can use Xml serialization to read it into a class.Code:<nodes>
<node guid="fcf2664e-d641-48a7-a1aa-2e8fef5145e6">
<data>....</data>
</node>
<node guid="62040b2d-52a4-4ce0-814f-ff5530dde6fc">
<data>....</data>
</node>
</node>
In terms of fast lookup, you can then put each node into a dictionary object and use the guid as the key for fast retrieval.
If this sounds interesting, I can elaborate further.
very interesting, i didnt think of serialization, how execlly will it help?
can i maybe combine it with saving the xml as compressed?
the exect xml structure is like this:
<XML>
<HEAD>
<GUID>fcf2664e-d641-48a7-a1aa-2e8fef5145e6</GUID>
</HEAD>
<BODY>
<DATA>.....</DATA>
</BODY>
</XML>
and under the data there are more nodes.
