Hi, Working with the class RetrievalMethodResolver I got some problems, mainly when
the retrieved content was transformed using an XPath Transformer. For example using a “http://www.w3.org/TR/1999/REC-xpath-19991116” transformer, if the query returned more than
one node the code converted the result into a byte[]and
tried to parse it again. That resulted in a fail,
because the parser cannot parse the resulting structure. It also made an
unnecessary reparsing of the retrieved nodes that caused an extra overhead. To reproduce this error you
can try to parse the signature provided inside
data/org/apache/xml/security/temp/key/retrieval-from-same-doc.xml of the
current release. When executing the xpath transformation (ancestor::my:KeyMaterials[@Id="thecert"]) 2 nodes where retrieved and when the method tried to
parse the result to get a KeyInfo (or child) node an
error was raised. I made a refactor
of the code supporting this case and eliminating the need of reparse the xpath resulting set if the XmlSignatureInput
contains a node. I don’t know how to
contribute it so I post it to you , hope this will be
useful to someone ;). Regards Dave Garcia |
