E [Xerces] cvc-complex-type.2.4.d: Invalid content was found starting with
element 'sld:VendorOption'. No child element is expected at this point.

Hi,

that is the SLD that works in geoserver 2.3.3. At the bottom.
But first please read what was wrong with it, as this may to help you to
help yourself next time.

The editor complained first about the <VendorOption> tag. Unfortunately XML
error messages in editors or geoserver are not very precise. So it pays to
look as well at the tag before as this may be the reason:
Here it is the case:
<sld:Halo>
<sld:Radius>
<ogc:Literal>1.5</ogc:Literal>
</sld:Radius>
<sld:Fill>
<sld:CssParameter
name="fill">#000000</sld:CssParameter>
</sld:Fill>
</sld:Halo>
The fill parameter is part of the Halo. On its own geoserver does not know
what to do with it, so the closing </Halo> tag needs to be after </sld:Fill>
not after the radius. So taking out the vendorOption would have resulted in
complaining about the <sld:TextSymbolizer> and that should have prompted you
to say: Hold on there must be something wrong before that....

Next problem: It is not <sld:Literal>, it is <ogc:Literal>. Literal is a tag
from a different namespace.

Next problem, where it is again complaining about the FOLLOWING tag i.e.
<sld:Font> not about the offending tag.

<sld:Label>
<ogc:PropertyName>nombre</ogc:PropertyName>
</sld:Label>

The label ends after the String you are using as label. Font is a subtag of
<sld:TextSymbolizer>. Essentially they come in the order how, what , which
font, where, halo, Fill. All these tags are on the same level. So closing
the </sld:Label> after the font does not work, although the XML is well
formed.

You have then three tags which do not have any content. And geoserver
complains about them as well. Rightfully I would say. Why do you have
placement tags when you do not say where.

<sld:LabelPlacement>
<sld:LinePlacement />
</sld:LabelPlacement>

On second thoughts the complaint may actually be because of the required
order of the tags.
Line 506 - 514 from the 1.0.0 schema:
        <xsd:extension base="sld:SymbolizerType">
          <xsd:sequence>
            <xsd:element ref="sld:Geometry" minOccurs="0"/>
            <xsd:element ref="sld:Label" minOccurs="0"/>
            <xsd:element ref="sld:Font" minOccurs="0"/>
            <xsd:element ref="sld:LabelPlacement" minOccurs="0"/>
            <xsd:element ref="sld:Halo" minOccurs="0"/>
            <xsd:element ref="sld:Fill" minOccurs="0"/>
          </xsd:sequence>
So the schema says: this must be your order. And that is why the
vendorOptions need to come last. Please note; There is a difference between
the Fill of the entire Labeling and the fill of the halo, I didn't know what
you want and assumed the halo below.

Now the sld that works (at least on my geoserver):

Ok Christian, is right, the SLd that you send work, i mean, it dont
present error, but is not doing that i want, i need that the streets's
labels beens showed following the curves of the streets, but this
solution are showing only the lines not the label, or i got something
wrong with my layer, i'll send it to you that you verify it, or i got
something wrong with my geoserver, i dont know, i am only an amateur
in this question please help me, tell me what software do you use to
get all thats error, thanks, here i send you the shapefile of the
streets of my project, thanks a lot.

Hi,

that is the SLD that works in geoserver 2.3.3. At the bottom.
But first please read what was wrong with it, as this may to help you to
help yourself next time.

The editor complained first about the <VendorOption> tag. Unfortunately XML
error messages in editors or geoserver are not very precise. So it pays to
look as well at the tag before as this may be the reason:
Here it is the case:
<sld:Halo>
<sld:Radius>
<ogc:Literal>1.5</ogc:Literal>
</sld:Radius>
<sld:Fill>
<sld:CssParameter
name="fill">#000000</sld:CssParameter>
</sld:Fill>
</sld:Halo>
The fill parameter is part of the Halo. On its own geoserver does not know
what to do with it, so the closing </Halo> tag needs to be after </sld:Fill>
not after the radius. So taking out the vendorOption would have resulted in
complaining about the <sld:TextSymbolizer> and that should have prompted you
to say: Hold on there must be something wrong before that....

Next problem: It is not <sld:Literal>, it is <ogc:Literal>. Literal is a tag
from a different namespace.

Next problem, where it is again complaining about the FOLLOWING tag i.e.
<sld:Font> not about the offending tag.

<sld:Label>
<ogc:PropertyName>nombre</ogc:PropertyName>
</sld:Label>

The label ends after the String you are using as label. Font is a subtag of
<sld:TextSymbolizer>. Essentially they come in the order how, what , which
font, where, halo, Fill. All these tags are on the same level. So closing
the </sld:Label> after the font does not work, although the XML is well
formed.

You have then three tags which do not have any content. And geoserver
complains about them as well. Rightfully I would say. Why do you have
placement tags when you do not say where.

<sld:LabelPlacement>
<sld:LinePlacement />
</sld:LabelPlacement>

On second thoughts the complaint may actually be because of the required
order of the tags.
Line 506 - 514 from the 1.0.0 schema:
        <xsd:extension base="sld:SymbolizerType">
          <xsd:sequence>
            <xsd:element ref="sld:Geometry" minOccurs="0"/>
            <xsd:element ref="sld:Label" minOccurs="0"/>
            <xsd:element ref="sld:Font" minOccurs="0"/>
            <xsd:element ref="sld:LabelPlacement" minOccurs="0"/>
            <xsd:element ref="sld:Halo" minOccurs="0"/>
            <xsd:element ref="sld:Fill" minOccurs="0"/>
          </xsd:sequence>
So the schema says: this must be your order. And that is why the
vendorOptions need to come last. Please note; There is a difference between
the Fill of the entire Labeling and the fill of the halo, I didn't know what
you want and assumed the halo below.

Now the sld that works (at least on my geoserver):

                          <VendorOption

                  </sld:Rule>
              </sld:FeatureTypeStyle>

Well enough explained?

Cheers

Christian
