Content is not allowed in prolog.

[Gabriel Bermudez]

Hi,

I can't seem to get rid of these message no matter what I do.  I have the following original config file:

<?xml version="1.0" encoding="UTF-8"?>
<qbean>
    <attr>1</attr>
</qbean>

And the following processor configuration

<?xml version="1.0" encoding="UTF-8"?>
<processor>
    <modify>
        <name>//qbean/attr</name>
        <value>100</value>
    </modify>
</processor>

So what want to achive is the following file

<?xml version="1.0" encoding="UTF-8"?>
<qbean>
    <attr>100</attr>
</qbean>

But for some reason I always get is "Content is not allowed in prolog." The configuration of the plugin is as follows

<plugin>
                    <groupId>com.google.code.maven-config-processor-plugin</groupId>
                    <artifactId>maven-config-processor-plugin</artifactId>
                    <version>2.2</version>
                    <executions>
                        <execution>
                            <goals>
                                <goal>process</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <transformations>
                            <transformation>
                                <type>xml</type>
                                <input>src/main/resources/config-proc/switch.xml</input>
                                <output>src/main/resources/deploy/switch.xml</output>
                                <config>src/main/resources/config-proc/switch-todofacil.xml</config>
                            </transformation>
                        </transformations>
                    </configuration>
                </plugin>

Do anyone knows what I'm missing. Thanks for you help.

Hi,

It may be the issue described at [1] or [2]. Can you please attach the exact xml files you're using and the complete stacktrace?

Hi Leandro,

Thanks for your answer. I'm attaching the whole project but I can't get the full stack trace. What I get is the following error:

[INFO] Processing file [src/main/resources/deploy/switch.xml] using config [src/main/resources/cfg-proc/switch-test.xml], outputing to [/home/gabriel/devel/workspace/cfg-proc/target/cfg-proc-1.0.0-SNAPSHOT/deploy/switch.xml]
[Fatal Error] :1:1: Content is not allowed in prolog.

The error should be reproducible by extracting the file and running

mvn -X -Ptest clean com.google.code.maven-config-processor-plugin:maven-config-processor-plugin:process

Thanks for your help again.

Ok,

The plugin assumes an XML value for modify actions, so the following
will do what you want:

<modify>
<name>/qbean/attr</name>
<value>
<![CDATA[
<attr>100</attr>
]]>
</value>
</modify>

You can also use find/replace like this:

<modify>
<find>1</find>
<replace>100</replace>
</modify>

I've created issue 40 to implement a way to make this kind of
modification almost like what you've configured initially.

Thanks for spotting that.

Hi Leandro,

I tried the change and works like a charm.  Thanks for you help and I look forward to the new feature.
