Hudson commented on AXIOM-478: ------------------------------ SUCCESS: Integrated in axiom-trunk #2426 (See [https://builds.apache.org/job/axiom-trunk/2426/]) AXIOM-478: * Allow OMElement#getTextAsStream to use the feature implemented in AXIOM-288 so that caching will be reenabled after the stream is closed. * Update the Javadoc to document the requirement to close the Reader. * Throw a meaningful exception when the next() method is invoked on a builder with caching disabled. (veithen: rev 1725612) * axiom/aspects/om-aspects/src/main/java/org/apache/axiom/om/impl/common/AxiomElementSupport.aj * axiom/axiom-api/src/main/java/org/apache/axiom/om/OMElement.java * axiom/axiom-api/src/main/java/org/apache/axiom/om/impl/builder/StAXOMBuilder.java * axiom/testing/axiom-testsuite/src/main/java/org/apache/axiom/ts/om/element/TestGetTextAsStreamWithoutCaching.java > Solution for parsing large XML > ------------------------------ > > Key: AXIOM-478 > URL: https://issues.apache.org/jira/browse/AXIOM-478 > Project: Axiom > Issue Type: Question > Reporter: LU Jie > > This is LU Jie from IBM. We use axiom to parse Atom in our project. > One of our CMIS API will attach file content to the XML. If the file size is > large, we will get a large atom. > If we use Entry.getExtension(QName) to parse the content, it will allocate a > large memory(around 5-6 times of the file size). > We need you help to clarify if we can use DOM-like API of axiom to get the > text of a certain element as stream. That is without allocating a large > object in memory. > Or is there an alternative solution for this use case? > We DO know that we can use pull-parser to parse the XML as stream. But we > need help to investigate if axiom has already provided an API or solution to > avoid writing parser by ourselves. > Here's the sample XML. We need to parse the text of cmisra:base64 element: > {noformat} > <atom:entry > xmlns:atom="http://www.w3.org/2005/Atom" > xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/" > xmlns:chemistry="http://chemistry.apache.org/" > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/"> > <atom:id > > xmlns:atom="http://www.w3.org/2005/Atom">urn:uuid:00000000-0000-0000-0000-00000000000 > </atom:id> > <atom:title > xmlns:atom="http://www.w3.org/2005/Atom" > type="text">doucment1446016556658.txt > </atom:title> > <atom:updated > xmlns:atom="http://www.w3.org/2005/Atom">2015-10-28T07:15:57.594Z > </atom:updated> > <cmisra:content > xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/"> > <cmisra:mediatype > > xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/">text/plain > </cmisra:mediatype> > <chemistry:filename > > xmlns:chemistry="http://chemistry.apache.org/">doucment1446016556658.txt > </chemistry:filename> > <cmisra:base64 > > xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/">Base64 > encoded content of large file > </cmisra:base64> > </cmisra:content> > <cmisra:object > xmlns:cmisra="http://docs.oasis-open.org/ns/cmis/restatom/200908/"> > <cmis:properties > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/"> > <cmis:propertyId > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/" > propertyDefinitionId="cmis:objectTypeId"> > <cmis:value > > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/">snx:file > </cmis:value> > </cmis:propertyId> > <cmis:propertyString > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/" > propertyDefinitionId="cmis:name"> > <cmis:value > > xmlns:cmis="http://docs.oasis-open.org/ns/cmis/core/200908/">doucment1446016556658.txt > </cmis:value> > </cmis:propertyString> > </cmis:properties> > </cmisra:object> > </atom:entry> > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@ws.apache.org For additional commands, e-mail: dev-h...@ws.apache.org
