xmllint

I have a collection of XML files, and some of them are pretty big (up to ~50 million element nodes). I am using xmllint for validating those files, which works pretty nicely even for the huge ones thanks to the streaming API. xmllint --loaddtd --stream --valid /path/to/huge.xml I recently learned that xmllint is also capable of doing command line XPath queries, which is very handy. xmllint --loaddtd --xpath '/root/a/b/c/text()' /path/to/small.xml However, these XPath queries do not work for the huge XML files. I just receive a "Killed" message after some time. I tried to enable the streaming

For the below xml ,I need to replace <studentStatus> for <studentName>CLASSA</studentName> to <studentStatus>failed</studentStatus> . <studentFile> <student> <studentName>CLASSA</studentName> <studentStatus>Success</studentStatus> <studentActions> <studentAction> <studentType>Juniour</studentType> <studentStatus>Completed</studentStatus> <studentMsg/> </studentAction> <studentAction> <studentType>HighSchool</studentType> <studentStatus>Completed</studentStatus> <studentMsg/> </studentAction> </studentActions> </student> <student> <studentName>CLASSB</studentName> <studentStatus>Success<

I'm trying to extract the value of a node from a pom.xml: <?xml version="1.0" encoding="UTF-8"?> <project> <parent> <groupId>org.me.labs</groupId> <artifactId>my-random-project</artifactId> <version>1.5.0</version> </parent> ... </project> I need to extract the artifactId and version from the XML using a shell command. I have the following requirements/observations: The shell script will be done within a build assembly file we use at work, so the smaller the script the better. Since it'll be used on multiple systems (usually RHEL5), I'm looking for something that can run natively on default

I am using xmllint to do some validations and I have an XML instance document which needs to validate against two schemas: one for the outer "envelope" (which includes an any element) and one for the particular payload. Say A.xsd is the envelope schema, B.xsd a payload schema (there are different possible payloads) and ab.xml a valid XML instance document (I provide an example at the end of the post). I have all three files locally available in the same directory and am using xmllint to perform the validation, providing as the schema argument the location of the outer (envelope) schema:

I created the following XSD (with Eclipse): <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="http://www.example.com" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://www.example.com"> <element name="Make"> <complexType> <sequence> <element name="Scope"></element> </sequence> </complexType> </element> </schema> and validating with this simple XML <?xml version="1.0"?> <Make xmlns="http://www.example.com"> <Scope> </Scope> </Make> gives: xmllint.exe --noout --schema sources.xsd sources.xml sources.xml:3: element Scope: Schemas validity error : Element '{http://www

Today I get to learn how to use xmllint properly. It does not seem to be well covered or explained. I plan to use a single language resource file to run my entire system. I have a mixture of bash scripts and php pages that must read from this language file. Currently I am using the following format in my xml file en.xml: <?xml version="1.0" encoding="utf-8"?> <resources> <item id="index.php"> <label>LABEL</label> <value>VALUE</value> <description>DESCRIPTION</description> </item> <item id="config.php"> <label>LABEL</label> <value>VALUE</value> <description>DESCRIPTION</description> </item> <
