python - ElementTree namespace incovenience -

-

i can't control quality of xml get. in cases is:

<collada xmlns="http://www.collada.org/2005/11/colladaschema" version="1.4.1"> ... </collada>

in others get:

 <collada>...</collada>

and guess should handle

 <collada:collada xmlns:collada="http://www.collada.org/2005/11/colladaschema">  ...  </collada:collada>

it's same schema over, , need 1 parser process it. how can handle these cases? need xpath , other lxml goodies through this. how make consistent during etree.parse time? don't want check on namespaces every time need use xpath.

my usual recommendation preprocess first, normalize namespaces. has 2 benefits: normalization code highly reusable, because doesn't depend on how data being processed subsequently; , logic process data considerably simplified.

if documents use 1 namespace, or none, , not use qualified names in content of text or attribute nodes, transformation achieve normalization simple:

<xsl:template match="*">   <xsl:element name="local-name()" namespace="http://www.collada.org/2005/11/colladaschema">     <xsl:copy-of select="@*"/>     <xsl:apply-templates/>   </xsl:element> </xsl:template>

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
