Memory rise with DOMDocument::getElementsByTagName method
---------------------------------------------------------
Key: XERCESC-1465
URL: http://issues.apache.org/jira/browse/XERCESC-1465
Project: Xerces-C++
Type: Bug
Versions: 2.5.0
Environment: RH 9
Reporter: Smtia Zankar
We are using the function DOMDocument::getElementsByTagName in our
application. We have observed that whenever this function gets called
there is an increment in the Memory consumed by our application.
The memory goes up every x times. The memory rise is visible for every x
operations or calls to this method where x is typically greater than 1000.
The application does the following.
- Maintains a XML for storing entries and their attributes.
- Number of entries can be any number from few hundreds to thousands.
- Every entry is identified with a unique number which forms the tagname
- While adding a new entry, a check is performed using the
getElementsByTagName function to see if the entry already exists.
- Also while deleting and modifying the attributes for the entry the
particular XML element is fetched using getElementsByTagName.
